Biodiversity
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),...
However, simply being a non-native species does not always mean it is invasive. To be termed "invasive," a species must cause damage to either human society or the naturally occurring ecosystem. This means that species that are non-native but non-damaging are not considered to be "invasive;" there must be damage to the biodiversity of an ecosystem. For example, many non-native species that have escaped from human control and are considered to be "feral" are…

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
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
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
However even if they are readily available with time the reserves will be depleted and this will pose as a challenge not only to the forest ecosystem but also the energy demands. On the other hand the use of renewable source of energy is beneficial since they are environmental friendly. The renewable energy sources also have some risks such as the use of hydro projects can affect forest ecosystems

International Environmental Law and its Impact on Australia Sustainable Development: A Global Challenge For many years, sustainable development has been one of the controversial issues faced by world leaders and citizens (Parmetier, 2002). The issue pervades both private and public sectors, and is
At a most simplistic level, the growth of the human population generates higher levels of consumerism. And the higher levels of consumption place supplementary strains on the already scarce natural resources. Additionally, the incremental levels of consumption translate into higher levels of waste. This waste comes from both individual consumers, as well as from industrial agents and it directly impacts the quality of the water as well as the
