iodiversity in Lake aikal
We are in a world where there is a continuous exploitation of natural resources and very little care about the environmental consequences. Rapid industrialization has created havoc to the delicately balanced ecosystems. The effect that human population has had on global ecosystem is certainly undeniable and global biodiversity is being seriously challenged. The rapid deforestation of Amazon forest, the irreparable damage that we have done to the coral reefs along the Great arrier Reef and the Caribbean coasts are examples of man made ecological disasters. Environmentalists world over are alarmed at the pace at which our economic ambitions are driving the ecosystem out of balance. The case of 'Lake aikal' offers an excellent example of one of the largest and oldest fresh water eco systems which sustains a wide variety of flora and fauna and in particular innumerable endemic species. For millennia Lake aikal's ecosystem has…… [Read More]
Because society is built upon the concept of money, the first and most important advantage of biodiversity is economic. Commercial, agricultural and pharmaceutical value can be derived from greater biodiversity. Indeed, increased biodiversity in rainforests is beneficial, because it derives a greater likelihood for the discovery of life-saving products. Critics might however argue that the likelihood of this is not very significant, and the process of "bioprospecting" for the purpose of conservation does not compare well in terms of costs and benefits. The prospect of benefits is somewhat small and unlikely in terms of the cost incurred. Another economic possibility Atkinson addresses is the possibility of ecotourism. This is a somewhat better prospect in terms of money that tourists are willing to invest in seeing animals in their natural habitats.
In conclusion, I do not think that biodiversity is overprotected, if one is to understand the term quite literally. On…… [Read More]
The human-caused change that is the greatest threat to biodiversity is anthropogenic climate change, which is caused by the burning of fossil fuels. This will create massive climate change, affecting the habitats where species live, causing significant issues that could affect their future survival, if they cannot adapt. This paper focuses on how these changes will affect biodiversity at the ecosystem level. The authors choose this focus because the ecosystem is a set of related entities -- individual species, for example -- but their interrelation is critical. If climate change affects a single species, it could disrupt the entire ecosystem even if the other species are not affected by the climate change. This example highlights the destructive capabilities of climate change.
One of the main points that the authors make is that a single species can and does affect an entire ecosystem. They discuss the removal of a single…… [Read More]
When increased funding is made available via investments and tourism, the space problem can also be managed with greater ease. It is vitally important to preserve as much biodiversity as possible, and to do so particularly in countries where biodiversity is richest. For this reason, conservation managers need to put practices in place to target potential investors for the future preservation of the earth and its resources.

Many nations have developed their own laws aimed at protecting and even increasing biodiversity when possible; some well-known pieces of legislature in the United States include the Endangered Species Act, which was actually passed more than a decade before the term biodiversity was coined, and the Soil and Water Conservation Act and Clean Air Act, both of which were not specifically aimed at maintaining levels of biodiversity or slowing the rate of biodiversity oss, but which have these effects regardless (Faith 2007). Following the Convention on Biological Diversity in 1992, many other nations also began passing laws, and international laws and standards were also set (Pethiyagoda 2004). Ironically, some scientists claim, some of these laws are actually so restrictive that they are prohibitive to research attempts that would aid in the conservation effort by providing deeper and richer understandings of specific ecosystems and environments that are high in biodiversity (Pethiyagoda…… [Read More]
Interdependence of Species Results: Round Species Missing (Bead Color and Name)
If trees and flowers were not part of the ecosystem, then there would be a lack of food for bees, lack of pollination for flowers, and then lack of agriculture for humans.
Explain how the ecosystem was affected by the missing species for each round of the demonstration.
Round 1 = Flowers removed
Round 2= Bees removed
Round 3= Trees removed
Round 4= Humans removed
In the first round, the flowers were removed which also removed food for the bees; in the second round there were no bees to pollinate the remaining trees; in the third round there were no trees to protect, shelter and encourage flora; in the last round no humans, which had the least effect on the entire ecosystem, but without flowers, bees and trees;…… [Read More]
The natural environment is the source of all our resources for life. Environmental processes provide a wealth of services to the living world -- providing us with air to breathe, water to drink and food to eat, as well as materials to use in our daily lives and natural beauty to enjoy.
Complex ecosystems with a wide variety of plants and animals tend to be more stable. A highly diverse ecosystem is a sign of a healthy system. Since all the living world relies on the natural environment, especially us, it is in our best interests and the interests of future generations to conserve biodiversity and our resources.
I know that some may argue that some species have become extinct, with no obvious effect on the environment. I put forth an answer to that statement; the Earth's systems are so complex that we are still learning about environmental processes…… [Read More]
Preserving Biodiversity and the Ecosystem Services it Provides
The diversity of life found on Earth represents an enormous asset. The extent of how this asset is valued is far from understood and its value most likely far exceeds any economic estimate. However, by framing the issue in terms of economics and the benefits that the ecosystem services provide to mankind this concept will likely garner more support than using vague and disconnected rhetoric. The services nature provides are incredibly valuable to the health and well-being of humans and they need to be made aware of this fact in way in which they can begin to appreciate the value of the services nature provides them in terms in which they can appreciate. If this approach can resonate with people then it will certainly gather more support than previous attempt to engage with the population.
The most important step is to…… [Read More]
These forests "loose their leaves during the dry winter but are lush and verdant in the summer rainy season" (Lewis 82).
Some of the varieties of flora in these regions include the pink trumpet, cardinal sage and the spider lily. Along the dry Pacific coastal plain, from the southern end of the Sonora desert to the state of Guerrero, the predominant vegetation is thorny bushes and small trees, including morning glory, acacias and savanna. Some of this flora occurs naturally, while others occur on over-grazed grasslands or abandoned slash-and-burn farmlands. Patches of semi-deciduous tropical forest reach almost to the sea near the Guerrero-Michoacan border. The coastal lagoons that dot the Pacific coast are home to dense mangrove forests that have thick, leathery leaves and small seasonal flowers.
As to the fauna, many animals can be found living among the lowland plains and along the edges of the vast mountainous areas…… [Read More]
Biodiversity Loss Threatens Human ell-Being" the authors list a number of components of biodiversity that contribute to the long-term provisioning of ecosystem services. Those components include the amount and stability of the total biomass produced, preservation of the soil, regulation of water availability, pollination and seed dispersal, resistance to invasive species, pest control, regulation of climatic conditions through a feedback mechanism, regulation of carbon sequestration in the biosphere, and protection against natural hazards (storms, floods, fires, etc.). (Diaz 1300) hile all of these are important, the regulation of water may be the most important as water is the basis of all life. The amount of water is the limiting factor in any ecosystem and therefore is the most important aspect.
In the event that scientists are asked to restore and preserve ecosystem services the most important components would include "restoring the biological integrity in terms of species, composition, relative abundance,…… [Read More]
The definition of "biodiversity" can be somewhat complicated, but in simple terms, "biological diversity is the variety of life and its processes; and it includes the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur." ("Scientific Definitions") While this definition contains several aspects, including the variety of species, their processes, and genetics, a major aspect of biodiversity is the communities, or ecosystems where they exist. This aspect of biodiversity also implies that the species, or organisms in a particular area are naturally occurring; and are not what are known as "invasive species." These particular species are not part of the naturally occurring ecosystem and can also cause great harm to the naturally occurring biodiversity of an area.
According to the National Invasive Species Council (NISC), and invasive species can be defined as "a non-native species whose introduction does or is…… [Read More]
Incentives to Conserve Marine Biodiversity Conservation ithin the Framework of Impure Public Goods
On the surface, environmentalism might seem like an 'easy' thing to sell to the American public. After all, marine biodiversity (to take one example) might seem like an uncomplicatedly 'good' thing -- it is necessary to preserve the health of the planet and by extension, the human species. "Biodiversity or biological diversity is defined [as] the variability among living organisms from all sources, including, inter alia [among other things], terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part: this includes diversity within species, between species and of ecosystems" ("hat is Biological Diversity or Biodiversity," Marine Bio). Species, genetic, and ecosystem diversity are all comprised within this definition ("hat is Biological Diversity or Biodiversity," Marine Bio). However, preserving adequate biodiversity has still proven to be challenging, despite the profound need to do…… [Read More]
e., caused by humans) mass extinction (2009). It is has been noted by scientists that it takes approximately 10 million years before biological diversity can even begin to get near what it existed before it died off. Over 10,000 scientists in the World Conservation Union have come up with data showing that "51% of known reptiles, 62% of known insects, and 73% of known flowering plants are in danger along with many mammals, birds and amphibians" (2009).
McKinney and Lockwood (1999) came up with a list of traits that influence whether species are "winners" or "losers" in a human-dominated world. Traits promoting range expansion were: selected traits (small size, high fecundity); high variability; widespread; rapid dispersal; generalist (eurytopy); and human commensalism. Some of the traits promoting extinction were: selected traits (large sixe, low fecundity); low variability; rare; slow dispersal; specialist (stenotopy); and poorly adapted to human activities (1999).

Lake Tahoe Biodiversity
Lake Tahoe is hailed as one of the most beautiful lakes in the United States. Over the last century or two, the fish biodiversity of the area has been a sight to behold. However, biodiversity tends to change over time. This particular report focuses on fish and there is much to be said even about fish in particular. This report will consult multiple sources and will create a rough timeline of what has been happening with the fish biodiversity of Lake Tahoe over the last one hundred and sixteen years. While some fish biodiversity changes are caused by entirely natural factors, human presence and activity has surely played a role as well.
One rather odd and vexing thing that has happened with the Lake Tahoe fish population over the years has been the introduction of non-native species to the ecosystem that is the lake. Indeed, there have…… [Read More]
Loss of Biodiversity
Biodiversity Loss and Mitigation
This essay will discuss the environmental citizenship concept and the different theoretical debates in the context of loss of biodiversity as well as its mitigation:
In our society, the life of human beings and business management have their foundation on a multitude of benefits from ecosystems -- many blessings of nature that come from natural assets such as water, air, soil, animals and plants. To continue benefitting from these natural assets, preservation of biodiversity is very important; however, there is a lot damage taking place on biodiversity and unfortunately, the rate at which it is happening is alarming ("Biodiversity Conservation - Environment - Sustainability - About Us - Panasonic," n.d.) mostly due to large scale globalization that engenders mass production, often at the cost of biodiversity. Therefore, it is expected that corporate enterprises should see to the conservation and sustainability of resources.

Economist on impacts of growth, "The Effects of Growth: The Long View" discusses, in brief, how economic development of human societies is actually beneficial to biodiversity, in spite of some negative aspects linked to it. It starts with a comparison of two nations -- South and North Korea -- and the way their economics and politics contribute to local biodiversity, that is, the region's forest cover. An identical comparison has been done of the Dominican Republic and Haiti; but this comparison has employed the nations' gross domestic products (GDPs) for proving impacts on biodiversity.
The next half of the article discusses how poverty poses the greatest challenge to biodiversity. It states that poverty has a greater adverse impact than human development on biodiversity. Furthermore, it remarks that poverty minus the presence of growth, together with an increasing population, proves disastrous to biodiversity. Meanwhile, even if growth accompanies poverty, the impact…… [Read More]
67). Two additional mammals that belong to these two orders are the zebra and the donkey (Perissodactyla) and the jaguar and the bobcat (Felidae).
A other insects are the boll weevil and the ladybug; in the order of Hymenoptera, two other insects are bees and wasps.
As to birds, they all share four specific characteristics, being that they have feathered wings (although some birds are flightless like the penguin), beaks, stereoscopic vision and are endothermic or warm-blooded. The differences between the pelican and the eagle are that pelicans generally live in a marine, saltwater environment and eat mostly fish, while the eagle lives predominantly in forested or mountainous areas and eats not only fish but also various land animals such as rabbits and other small mammals. As to order, the pelican belongs to Pelecanidae, due to exhibiting a pouch under their beaks, while the eagle belongs to Accipitriformes, due to…… [Read More]
Biodiversity is a term which refers to the amount and degree of diversity found within living biology. Biodiversity is likely best measured as the sum total of the number of existent creatures, systems, and variety of creatures found within the world at large (National Geographic, 2016). In order to best understand the significance of this statement, it is necessary to codify biodiversity into three different varieties. There are ecosystems, species, and genes which comprise all of the variety found within the notion of biodiversity (National Wildlife Federation, 2016). Therefore, all that is needed to determine biodiversity is to simply add the number of each ecosystem, species, and gene variation found.
The importance and benefits of biodiversity
Biodiversity is important because of the way that different living systems found within it interact with one another. Oftentimes there is a degree of dependence between those systems. It is worth noting…… [Read More]
Of the top 150 medications that are sold by prescription in the U.S. 118 of these are medications that are either "derived from or modeled on naturally occurring substances." (SEAM Global, 2005) Some of the medications that count on habitat presently being destroyed are "aspirin, morphine, vincristine, taxol, digitalis, and most antibiotics."(SEAM Global, 2005)
VI. Internet/Networking: Role Played in Preservation
Through global and subglobal assessments of the ecosystem and monitoring of data in relation to global changes information may be shared from one region to another and earlier attempts made in changing, slowing or altogether avoidance of more extreme conditions. As stated on the web page of "GreenFacts.org": "Some ecosystem problems have been reduced by innovative local responses...Therefore institutions are needed at multiple levels to strengthen the adaptive capacity and effectiveness of sub-national and local responses.

The essence of Zapatista philosophy and action is the discovery of a new order of revolution. In the wake of failures of other socialist movements from Lenin to in Russia to the Sandinistas in Nicaragua, the small group of Mayan farmers in southwestern Mexico contend not only with reconstructing revolutionary tactics but also with the massive opposition from dominant governments, including those in Mexico and the United States. Governments that continually uphold the principles of capitalism will find in the Zapatistas an idealistic, hopeless cause of swimming against the tide of globalization. Even before the ratification of the North American Free trade Agreement (NAFTA), Mexicans struggled with political and economic oppression. The indigenous peoples of Mexico, like the Mayan nations of Chiapas, fared worst. Lowest on the scale of economical, social, and political power, these individuals hearkened to the voice of their martyred namesake Zapata, who was murdered on…… [Read More]
134). In addition, ussian authorities have also joined with the international community to protect the lake. In this regard, Hudgins adds that, "Increased awareness of such threats to the unique ecology of Lake Baikal has prompted a number of international organizations -- including the Sierra Club and Baikal Watch in the United States -- to join the ussians in their efforts to protect this natural wonder of the world" (1998, p. 135). According to the Sierra Club, "Lake Baikal, arguably ussia's most significant environmental treasure -- it contains a fifth of the world's unfrozen freshwater and is a UNESCO World Heritage site -- is being polluted by toxic waste from a paper mill that Vladimir Putin ordered reopened for economic reasons" (Pollutin' Putin, 2010, para. 2). In fact, the recently reopened paper mill disposes of toxic wastes directly into Lake Baikal's fragile biological system (Hoare, 2008). While the Sierra Club…… [Read More]
In this regard, Green and her colleagues emphasize that, "The corporate wealth of logging giant Gunns, Ltd. (which controls over 85% of the state's logging, is the world's largest hardwood woodchip exporter, and is worth over one billion dollars) has not trickled down into the state's economy" (2007, p. 95).
Despite the enormous range of wood products, particularly its valuable hardwoods, that could be produced from Tasmania's forests, more than 90 per cent of the country's hardwood timber is simply processed into woodchips annually, representing 5,000,000 tons of Tasmanian native forest which are then marketed to paper mills in Asia, primarily in Japan but in South Korea and increasingly China as well, accounting for around 70 per cent of Tasmania's total woodchip export production (Green et al., 2007). The sustainment practices used by the forestry industry, though, have been insufficient to replenish what is being extracted.

What can the phenotype tell you about the genotype of an individual?
The genotype describes the genes inherited by an organism. Phenotype refers to an individual's anatomical structure, physiology and behavior. The phenotype refers to everything that can be easily observed and measured about a plant, animal or human being. Our phenotype is the product of Genes inherited from our biological parents,
And developmental noise
Phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). In a narrow "genetic" sense, the genotype defines the phenotype. But how, in and evolutionary sense, does the phenotype "determine" the genotype? Selection acts on phenotypes because differential reproduction and survivorship depend on phenotype. If…… [Read More]
Systematics is one of the main fields of study in biology wherein the historical relationships of groups of biological organisms are studied. Through systematics, scientists are able to identify organisms existing in this world in accordance to their classification, group, phylum, and other hierarchical positions in the biological strata. Apart from studying the relationship of organisms with each other and in their environment, systematics also aims to determine patterns in the organism population where groups of organisms are most likely to thrive and survive. Systematics as scientific methodology in biology is essential to the establishment and maintenance of biodiversity. This is because through systematics, biodiversity existing in the Earth are identified and documented, converting these information into understandable / comprehensible and thereby useful information to other people. It is also a method and study where the life history of the Earth is documented. Systematics also makes it easier for…… [Read More]

Nevertheless, it is a conceptual change from government-sponsored conservation efforts of the past, which might have focused specifically in the same region on the manatee population, and thus played a pure game of numbers. To regard the Florida manatee instead as part of a larger ecosystem that must be monitored in numerous different ways requires a change in approach which is not always easy for a government agency to implement.
2. The chief conservation implication of introduced invasive species is that the invasive species is often very difficult to eradicate without serious disruption to the host ecosystem. An excellent example of an invasive species is presented by the zebra mussel, a small freshwater species of shellfish originally native to the freshwater lakes of southern ussia. The introduction of zebra mussels into the freshwater habitats of North America has allowed them to spread at astonishingly fast rates: the zebra mussel reproduces…… [Read More]
Part 1: A Closer Look at the Evidence
1. The first graph on the NASA site shows the concentration of CO2 in the atmosphere, comparing across time. It shows that for all time, there were fluctuations in the level of CO2 in the atmosphere, but that the level always remained below 300 parts per million. The graph takes a sharp uptick in recent years, and by the time we get to the 20th century it is basically a straight upward line, to the present level around 400ppm. The 1950 level was only at around 320, so nearly a quarter of the carbon in the atmosphere has been added in about the last 70 years or so, and that is for all-time.
The UK website explains that the increase in carbon dioxide levels in the environment has occurred since the Industrial Revolution, which brought about many changes in technology, including the…… [Read More]
So far, this is not the case, and oil companies only pay royalties on production. This is another area under scrutiny in the MMS scandal. There are reports, dating back to 2008, that the royalty offices of the MMS, located in Denver, routinely accepted oil company numbers on the amount of oil they produced, rather than independently auditing the numbers. No one knows how much lost revenue to the government that practice resulted in, and there is no way of finding out now. Clearly, future policy formation on the industry needs to include more oversight, more regulations, and a much less cozy relationship between the regulators and the companies they are regulating.
Future policy formation on other energy sources

But the supply far outstrips demand, Europeans are finding. The climate of this marketplace itself is decidedly cloudy. Advance prices have plunged by half.
At this point, one shouldn't portray it as a liquid, vibrant market," said Atle C. Christiansen of PointCarbon, a Norway-based research firm (Climate, 2004).
More than six years after governments negotiated the historic climate accord in Kyoto, Japan, the world is taking only halting steps _ not always forward, never in unison _ to follow through (Climate, 2004).
In fact, the Kyoto treaty itself is not yet in force, since it hasn't been ratified, as required, by industrial countries emitting a total of 55% of "greenhouse gases," such as carbon dioxide, that trap heat in the atmosphere that Earth otherwise would give off.
ussia's expected accession later this year would clear the 55% hurdle. But even a functioning Kyoto agreement would have little impact: Its limited…… [Read More]
According to The orld Commission on Environment and Development (CED), "Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs." There are many issues related to this important concept that have global implications. The purpose of this essay is to discuss the issue of consumption and how it affects the ability of the environment to continue sustainable living. This essay will first describe the issue and illustrate key points that relate consumption with sustainability. The next part of this argument will discuss the role of businesses and corporations and their relationship with this issue. The essay will conclude with commentary and conclusions about the current trends and future responses to consumption and the potential implications for businesses.
The Issue of Consumption

Yasuni National Park: Cultural Aspects that May Impact Biodiversity and Sustainability
The biodiversity record of Yasuni National Park is amazing – with the park being “the most biologically diverse hotspot in the Western Hemisphere” (Andrianos, Sneep, and Kerber, 2014, p. 32). It is important to note that in addition to having a healthy vertebrae assembly, Yasuni National Park also covers a relatively huge wilderness area and is home to a wide range of species (Andrianos, Sneep, and Kerber, 2014, p. 32). In addition to the Waorani communities, who have largely been seen as having been the ancestral guardians of Yasuni National Park, other indigenous groups who continue to live within the Yasuni National Park territory (in voluntary isolation) include the Taromenanes and the Tagaeris (Waller, 2016). The relationship of these indigenous populations with the environment has historically been harmonious. All along, they have mostly made use of natural resources for…… [Read More]
The role of the current in trajectory movements is significant, particularly in species such as the leatherback turtle, as it provides at times unexpected information regarding the animal's sense of direction and purpose in terms of its environment. In the conservation effort, it is therefore very important to consider the influence of current upon animal movement.
Conservation can only be effectively applied when behavior and movement are interpreted to the highest degree of accuracy. The study reveals the importance of current influence on marine life movement. Although larger and faster marine animals will not be as influenced by the current as the leatherback turtle, there will certainly be an impact. While important to study the movements of marine life, the influence of currents on the study of foraging behavior is even more important. This will determine the focus of conservation on specific foraging areas in order to ensure sustainability…… [Read More]
aising awareness about the presence of the disease amongst amphibian owners is essential, so they do not dispose of unwanted pets and infect wild populations. It is also essential that hikers and casual outdoor observers do not move frogs from one area to another, for fear of spreading the illness. Signs of the sickness in the frogs include discolored, peeling, or rough skin; lethargy, and lack of appetite. However, people should be aware that many frogs initially show no sign of the illness. Additionally, campers and hikers should "clean and dry all equipment and wet or muddy footwear before and between visiting frog sites. This may include cleaning the tires of your vehicle before visiting known high-risk sites where threatened frog species may live" (Frog, 2008, DECC). Zoos should also be made aware of the need to carefully monitor their amphibians, particularly because captive populations can be treated for the…… [Read More]
Damns on Wildlife and the Environment
Background to Dams and Levees - One of the issues resulting from civilization and urbanization is that most of the places humans chose to locate, for reasons of convenience, agriculture, transportation, and economic independence, have been near water. Dams provide hydroelectric power, help control floods, and make rivers navigable. Levees are quite similar to dams in their purpose, although they are primarily build to restrict water in times of high flow -- and for the majority of time are not under water. Per capita, floods are the most destructive and frequent of Mother Nature's natural disasters. In the last 50-60 years, in fact, the number and severity of flooding has worsened globally. Several reasons have contributed to this: global warming and worsening of storm activity; the deforestation and paving of natural watersheds; and more people living and working on known flood-plains. However, many scholars…… [Read More]
I would also like to know the suggested length of the canopy trees and the measurements of this 'partial shade'. (a third variable that I would like to know is what type of cacao they experimented with since there are different kinds).
These three aspects are important for the following reasons:
. The researchers may have studied only 2 rainforests in which case their research is insignificant. The rainforests may have had conditions that may have supported the researcher's conclusions -- we need a diversity of rainforests that contain different conditions in order to more reliably test hypothesis. The researchers may have conducted their research in an ad hoc manner or with certain shortfalls that would invalidate their conclusions. A scientific study needs to be both reliable and valid (in both external and internal way) to be accepted. Certain conditions for both elements need to be addressed. I would like…… [Read More]
firms have been focused on social responsibility. This is when a company will engage in different practices that take into account the viewpoints of various stakeholders (such as: communities, the environment and the impact on the firm).
In the case of Chevron, they claim that they are committed to protecting the environment at all costs.
Evidence of this can be seen with company's Operational Excellence Management System. Implemented in 2007, this is designed to take into account a number of different viewpoints when starting any kind of new project. The most notable include: possible social, environmental and safety issues. This program is illustrating how the company is focused on addressing issues that will be impacted by their activities.
However, Chevron is also dealing with challenges where they contributed to incidents that harmed the environment, health or interests of other stakeholders (i.e. The Brazilian offshore oil slick). The combination of these…… [Read More]
Environmental Case Study (Alberta's Oil Sands)
Alberta's Oil Sands represents one of the international environmental problems facing Canada and close to seventy countries across the globe. Albert's Oil Sands proves to be a new course of political conflict within the setting of Canada and at the international level. Oil Sands development is responsible for rapid economic growth of Alberta. This creates ethical or moral dilemma because there is a massive risk in association with the development of Oil Sands within the province. Oil Sands contribute towards ecological harm thus having a negative impact on the living conditions of the individuals in the province and the entire planet. This ethical dilemma leads to mobilization processes by environmental entities to help alleviate the situation. This is because some prominent political outfits such as Peter Lougheed recognize that the rate of the development of the oil sands in Alberta is not socially or…… [Read More]
Saudi Arabian Community: Problems and Solutions
The Saudi Arabian Community: Current Issues and Proposed Solutions
There are many problems affecting the Saudi Arabian community today. The said problems could be political, cultural, economic, or even environmental. This text concerns itself with a problem of an environmental nature. Two of the animals currently under threat of extinction in Saudi Arabia are the Arabian Oryx and the Saudi gazelle. ecently, pictures posted on the internet depicting slayed gazelles caused an outrage with most commentators branding the act irresponsible and intolerable (Toumi, 2013). If nothing is done to save the Arabian Oryx and the Saudi gazelle, the ecosystem could suffer great (and perhaps irreversible) damage.
I personally believe that we all have a role to play as we seek to save these two endangered species. It is for this reason that I have in the past shown great interest in this particular subject.…… [Read More]
In other industrialized countries, however, like Germany, Italy and Japan, the main concern of governments today is that not enough children are being born to even reach the level of the replacement rate. This is almost certainly a mistake since reduction of population should be the main goal in order to save the planet, and additional middle-class consumers in Western nations are the greatest burden on the environment.
Encouragement of voluntary euthanasia will be another method of reducing the excess population. Today many billions of dollars are spent on the last thirty days of life and 65% of physicians and nurses in one survey admitted that had provided unnecessary treatments for the terminally ill. That statistic was mentioned frequently in the debates over health care reform, with the implication that those dollars would be better spent on medical care for younger and healthier people at the start of their productive…… [Read More]
TED talk, Jason Clay talks about how the major buyers in the world like Cargill are the key to creating a sustainable future. Clay started out working on the side of the small farmers, going the traditional route of purchasing products at fair and equitable trade and driving consumer demand for sustainable products like Ben & Jerry's Rainforest Crunch ice cream. Then, Clay and his colleagues realized that they were not going to achieve their goals of massive transformations in the ways goods are produced without working with the big key players -- the organizations responsible for tearing down the rainforests to place cattle pasture or rainforests to plant palm oil plantations. Beef, lumber, soy, and certain types of fishing are among the top fifteen global products that are singularly responsible for much deforestation. ith current consumer-driven demand, there will be insufficient resources on the planet in the near future.…… [Read More]
Rutagarama, E. & Martin, a. (2006). Partnerships for protected area conservation in Rwanda.
The Geographical Journal, 172(4), 291-293.
Summary of the content: The authors work at the International Gorilla Conservation Programme, African Wildlife Foundation and School of Development Studies, University of East Anglia, Norwich, respectively, who emphasize the importance of developing networks of partnerships in developing countries that include national, regional and local government agencies as well communities, NGOs and the private sector to promote sustainable biodiversity conservation initiatives. Such partnerships can avoid the tendency to adopt extreme positions with respect to sustainable uses of natural resources such as the "fortress conservation" approach that discourages resource used by human populations on the one hand and the reckless use of natural resources with little regard for future sustainability on the other.

Conservation of ocean or marine life has attracted significant attention in recent years given the devastating impacts of human activities on these ecosystems. This paper examines a study conducted to promote conservation of marine or ocean life across the globe. The review demonstrates the significance of combining policy interventions and management interventions to achieve this.
Ocean or marine areas cover approximately 71% of the Earth’s surface. Even though the depths of these areas are yet to be fully explored or exploited, they are habitats for a huge portion of the world’s biodiversity and essential in global climate change (Addis, p.5). Ocean or marine biodiversity is recognized across the globe as an essential component of life not only in the oceans, but also on Earth. The Federal Ministry for Economic Cooperation and Development states that ocean or marine areas are key components of the Earth’s ecosystem to an extent that…… [Read More]
Wes Sechrest and Thomas M. rooks and published in the National Academy of Sciences reveals the results of a study they conducted investigating the varying levels of biodiversity distributed throughout the world. The authors employ a fairly novel approach in their measurements of biodiversity, specifically, relying upon two methods approximating the levels of evolutionary history endemic to twenty-five terrestrial "hotspots." The significance of evolutionary history as a measuring stick is that it is associated with the past importance of particular geographic locations, and implies that future evolution is threatened if these locations are threatened. Additionally, Sechrest and rooks find that their twenty-five defined hotspots house not only disproportionately large amounts of evolutionary history, but are also disproportionately threatened by the activities of man. The article stops short of attempting to identify any possible solutions to this impending problem, however, it does help to illuminate some of the shortcomings of our…… [Read More]
Additionally, conservationists suggest increasing patrols to improve overall enforcement of existing laws, better boundary demarcation, and the development of stronger hunting quotas. All of these measures require significant and lasting funding.
This Park is in a state of crisis. ith most of its large mammals now extinct from the Park, and illegal users on the rise, Park Rangers are simply outmatched. Poachers can find a thriving market for illegal bushmeat and rare birds. Illegal loggers easily find buyers for rare trees. The Park is under-staffed and under-funded and soon to face new challenges if the upstream dam is built along the Gambia River as planned.
The Galapagos Islands and the Niokola-Koba National Park represent two of Planet Earth's most valuable treasures. They contain biodiversity that not only provides scientific opportunity but may support the health of the entire ecosystem in their respective regions. Both sites are listed…… [Read More]

There are 1200 known species of fish and it is thought that there are as many as 1700 living in the Mekong River Basin. High diversity is present due to plant groups and other aquatic animal groups. The Mekong's ecosystem is one of complexity with variations in climate, geology, terrain and water flow." (Coates, et al. 2003) the results of these variations are a rich habitat that is said to 'rival that found on tropical coral reefs. The pictures below show the impact of the flooding of the Mekong.

The authors explain that "Large-scale habitat loss and fragmentation…" that results from urban sprawl is a major cause of the lack of biodiversity within the insect species (Acharya, 1999, 27). Even the building of a new road, or street lights, in places where previously there were no roads or lights, what the authors call "undisturbed areas," has an impact on insect biodiversity, Acharya explains. Meanwhile, moths, which are known to be drawn to light, have trigger mechanisms that detect the echolocation signals of bats; and on the other hand bats feed "…heavily" on moths, Acharya continues; in fact many bat species use moths as their "main food item" (Acharya, 27).
The point of that information (and of this study) in this peer-reviewed piece is that if "…eared moths" exhibit behaviors that allow them to avoid bat attacks, they would not be caught as often by bats and hence this would…… [Read More]

Explain what conservation biology is and highlight its goals.
Conservation biology is a branch of biological sciences which is primarily concerned with the preservation of life on earth including organisms which are classified as plants and animals. It examines biodiversity and ways and means in which the biodiversity of life on Earth can best be sustained (Sahney 2008,-page 759). This branch of biological study began as a reaction to the growing concern over extinction of species and disruption of habitats because of natural disasters and/or the actions and behaviors of human beings and industrialization. Interactions between species, particularly the interaction between humans and native populations is of particular interest to conservation biologists, particularly in terms of negative effects of human interaction.
The goals of conversation biologists are to protect various species as well as their habitats and ecosystems. They also want to prevent the extinction of species and…… [Read More]
Forests have long been exploited. They are harvested for their timber, or cleared for agricultural land, both activities being entirely destructive to the ecosystem. The fen exists typically within the forest, and is not usually subject to exploitation until the forest itself is, because the forest acts as a natural barrier for the fen. The destruction of forests for timber is arguably the lesser of the two forms of exploitation, at least in countries with active silviculture programs, as the forests will have the potential to regenerate. However the destruction of forest ecosystems is associated with several negative outcomes. The biodiversity of the forest system is reduced, and this effect is stronger the more forest is cleared. Destruction for agriculture is permanent, which means that the loss of biodiversity is permanent. Endemic and endangered species are rendered extinct, or their numbers reduced (Chediack, 2008).

S. production value. Exports account for approximately half this amount (Binnquist, Lopez, and Shanley). Figure 2 portrays three views of bamboo. One: A bamboo forrest; Two: A bamboos shoot; Three: A bamboo grove walkway.
Figure 2: Three Views of Bamboo (adapted from Stickman).
As bamboo production levels have risen, the amounts of raw materials needed to facilitate the production have simultaneously increased. The bamboo industry in Anji predominantly harvests bamboo from plantations, as it primarily grows a fast growing and easily cultivated, bamboo species, locally known as "maozhu" or "moso bamboo" (phyllostachys heterocycla) (Binnquist, Lopez, and Shanley). .
Currently in Anji, the cultivation of moso bamboo encompasses 60% of the forest area, with the percentage rising as plantations expand. Along with the hefty production of bamboo, the intense cultivation bamboo industry uses mammoth amounts of fertilizers and pesticides; which contributes to negative environmental effects. In reference to the bamboo production…… [Read More]
Compulsory Licensing of Patents
The purpose of this paper is to highlight the causes and affects of the compulsory licensing of pharmaceutical products. Initially, the paper highlights the fundamental positions, attitude, inclination and concerns of the developed world and the under developed world with regard to the intellectual property rights of the pharmaceutical products. The paper also concentrates on the subject of the intellectual property rights of the biotechnology products (plants); this is because plants are the major source of almost all pharmaceutical products being used today. Furthermore, it is a matter of fact that the patentability of plants has been given a lot of attention by the developed world, in particular United States of America, as well as, the developing World. The paper also exposes the priorities of both the developed world and the under developed world, priorities that have been a major hurdle in all previous negotiations on…… [Read More]

mass tourism on the culture of Ibiza
Ibiza in Spain is one of the best-preserved medieval islands in Europe. The island is closest of all the Balearic Islands to mainland Spain and has a 200 km coastline. Although it has a reputation as a party island, there is much more to it than nightclubs. There are many small coves and over 50 beaches. One can view other Ibiza attractions, museums, events, festivals and travel. Ibiza has earned the title of "Clubbing Capital" of the world. The temperatures range from 20 degrees Celsius in May to around 27 in August. The population hovers around 110000 while the language spoken is Castilian Spanish. The currency accepted is the Euro. During the 1990's, tourism was boosted in the island when it earned the Guinness ecord as the entertainment industry in the world. Since it has around 300 days of sunshine throughout the year,…… [Read More]
The study will be delving into: What ASEAN constitutes and what remains beyond its scope? The aim of this study will be handing out a wide-ranging presentation of the present stance of ASEAN and its accomplishments till date, along with its challenges. The paper is intended as a suggestion for a master-plan that can be employed as a future pathway where ASEAN political-security support must be going towards in the forthcoming years.
To start with let us have a brief introduction of the organization. The creators of the Association of South East Asian Nations - ASEAN, visualized it as ultimately assembling all the nations of the region and managing them to lend a hand in assuring the peace, permanence and growth of the area. While the area was in a state of turmoil, a lot of nations were under pressure for the existence of the nation or autonomy. First…… [Read More]
If there is an aggregate sub-base, these can provide water quality treatment. There should be good compaction and appropriate geo-textiles especially for areas accessible to heavy vehicles.
Permeable pavements reduce the need for deep excavations thereby providing a cost benefit. This system reduces the run-off rates and peak flow. The overall benefit is that it removes pollutants and holds water so that it does enter the main drainage. A lot of water in the main drainage would either need pumping or treating thereby using energy (Wild et al. 2002).
They are continuous vegetated drainage systems which convey or store water while allowing filtration when appropriate. Usually, they are the equivalent of roadside gullies or drainage pipes in conventional drainage systems. However, swales have gentle gradient so that water moves at low velocity. The sediments in storm water run-off can, therefore, settle out.
The advantage of swales is that…… [Read More]
Sustainable tourism does not destroy the environment, economy, or cultural aspects of the tourist destination (David Vaughan, 2000). Sustainable tourism is aimed at ensuring that those concerned are not affected in any way and that a positive development is realized through it. Back in the 1980s, ecotourism which consisted of activities such as wildlife exotic cultures and nature, became more common with remarkably few people understanding what the impacts of such tourism are, this led to its pitfall (Erlet, 1993). Therefore, sustainable tourism helps to improve all associated impact of tourism as a whole, and this can steadily be achieved through seeking partnership between various governments, local community and any stakeholder in the tourism industry.
How sustainable tourism can be achieved
esearches done in this field indicate that for sustainable tourism to be achieved all efforts should be channeled towards fostering co-ordination and cooperation between managers of the tourism destination…… [Read More]
Extinction Events or Environmental Catastrophes
Many uncertainties exist over the acts and roles of extinction in the world today. Nonetheless, with all these uncertainties, it is possible to formulate reasonable statements that depict the probable role of extinction. The role of extinction can be thought to have some elements, most of which are instrumental in striking the relationship and power seen in evolution and extinction in the earth's history up to the appearance of hominids (8 million years ago) . For any widespread species or any group of a widespread species, extinction needs some bit of environmental shock that comes in the form of physical or biological aspects that normally occur. Such occurrences take place during the geological lifespans of the given species or groups of species. In this case, the shock that is resulting has to be applied with a rapidness that is enough to take place over a…… [Read More]
2006). According to Branch et al., "Essentially, a public participation program may be deemed effective to the extent that it provides for open disclosure and addresses all four acceptability dimensions in ways that are appropriate and effective for a particular community and situation" (2006, p. 724). Therefore, the EPA's decision-making process in this case would likely have been different had all four of these dimensions being taking into consideration and efforts made to adequately satisfy each of these requirements in the final outcome.

..the giant salamander, 2010, Cryptozooscity).
There are fears that giant salamanders may meet the same fate as dinosaurs, given that modern life has exposed them to quick-moving, larger-brained humans who consider them a delicacy and will hunt them with greater determination than previous predators. The amphibian's size makes them "lucrative prey for hunters, who can sell the flesh for around U.S.$100 per kg (£30 per lb)," a considerable sum when one salamander can grow to over one hundred pounds (Black 2005). "They are protected species; but in China, illegal hunting is bringing them within sight of extinction" (Black 2005). Observed one conservationist: "They are easy to catch, hiding in rock crevasses during the day, and people know where to find them" (Black 2005).
The loss of these giant relics would not merely be a loss of a link to human evolutionary history of the past: the salamanders may also provide…… [Read More]
