¶ … Rapid Population Growth...
Though I am impressed and elated at the black-footed ferret's proven ability to come back from the brink of extinction and repopulate its natural habitat after captive breeding, something in the first paragraph of this article caught my eye and deserves, I believe some measure of reaction. What attracted my attention and caused me to bristle slightly is the fact that many endangered species bred in captivity and then re-released to their natural habitats "fail to produce self-sustaining populations" due in part to the "persistence of the environmental factors that caused the species to become endangered." Now, it does not particularly raise my wrath that the authors include this seemingly obvious statement in the first two sentences of their article, but the fact that this fact needs to be included is somewhat maddening. If the same environmental pressures that caused a species to become endangered still exist after a captive population has been bred, it seems like the most basic application of common sense would tell someone that this new population of the species will face the same endangerment.
The way that endangered species and their environments are handled is in need of reevaluation, and I believe that this statement by the authors of this article is proof of this. Obviously, breeding a species in captivity only to have them become endangered again when reintroduced to the wild is a waste of effort and money. I am not suggesting that instead nothing should be done to save these species, but what gets done needs to happen in a wiser fashion. The first -- and also most difficult -- step would be increasing environmental protection laws, especially in areas with endangered species. This would enable for quicker identification of problems leading to endangerment and more effective solutions. In addition, captive populations should be maintained until sufficient evidence as to the area's suitability for repopulation is ascertained.
Communities that understand the toll population growth has on the environment are more likely to take action to protect the environment and conserve natural resources by monitoring population growth and encouraging restoration of the environment rather than encouraging larger families (Mulligan, 2006). Community actions are more likely to be tolerated than mandates that declare population growth must be limited by force (Mulligan, 2006). Evaluate Effects of Human Activities on Ecosystems
Population and Consumption There are a few different links between poverty and population. The text notes (p.169) that "much of the recent international migration has been from the developing world to the developed world," and that many people migrate because they realize that their best chance to escape poverty is to move to another country. Yet, rapidly growing populations are also a contributing factor to poverty in the developing world. In
However, no investment can be considered free of risks. The most critical risks to firm operations are the traditional risks (government regulation/legal decisions, country financial risks, currency/interest rate volatility, political and social disturbances), the emerging risks (theft of intellectual property, security threats to employees and assets), and other threats such as: corporate governance issues, absence of rule of law, disruption of key supplier/customer/partner, product quality and safety problems, IT
Yet, in the world today there is an even greater fuel shortage, that can create an even greater human catastrophe, as trees create the oxygen that makes it possible to breath. A the urgent need to develop more climate-friendly energy technologies is becoming keenly appreciated worldwide. Renewable energy technologies are receiving heightened attention, and modern biomass-based energy -- the use of wood, crop residues and dung as fuel -- is
Chain migration refers to the migration of a population, whereas hierarchical migration refers to the migration of a certain segment of a population. As can be gathered by these factors that influence population growth, community interactions plays a dominate force in population dynamics. The concept of community interactions can be used to encompass such factors as migration, wealth and trade. In other words, each community has specific needs and resources.
Urbanization Earth also witnessed a phenomenon of urbanization or shifting of population toward cities. The increase in the number of cities has been associated with that of repeated ecological disaster. Rapid regional deforestation, the depletion of ground-water aquifers, accelerated soil erosion, plant genetic simplification, periodic outbreaks of disease among pest species and domesticated animals, large-scale human malnutrition, and the development and spread of epidemics are some of the results we have
