Question Details
Protection of a single endangered species in the United States involves the expenditure of millions of dollars of public and private funds for such actions as purchase of conservation lands, stormwater controls and habitat restoration.

In light of these financial costs, write a 700 to 1000 word essay on the potential costs to the ecosystem from the loss of a single endangered species, including how the extinction may affect other components of the ecosystem and its biodiversity.

Use Anthem’s eGlobal Library to research this topic, providing at least 5 specific citations to support your essay. Citations must be complete and are not included in the word count.

Explanation / Answer

Extinction / Loss of endangered species - Endangered species are living things whose population is so reduced that they are threatened with extinction. Thousands of species are included in this category. The International Union for the Conservation of nature and Natural Resources publishes a list of threatened mammals, birds, reptiles, amphibians, and plants. Causes for this extinction - Millions of years before humans, extinction of living things was linked to geological and climate. But today the major causes of extinctions are - Habitat degradation - Predation - Competition - Disease - Coextinction - Globalwarming Environmental change is still the primary cause of the extinction of animals, but now the changes are greatly accelerated by human’s activity.   --   Clearing land for farms and towns, lumbering, mining, building dams, and draining wetlands all alter the environments so extensively that ecosystems may be completely destroyed. With a burgeoning human population requiring food, shelter, and clothing and constantly demanding more energy-using devices, the temperation to exploit land for human use without regard for consequences is great. Frequently, several forms of environmental change are responsible for the disappearance of species.  They can include- -- For example, as tropical forests are cut down, primates have progressively smaller feeding and living spaces. They also become more accessible to hunters, who kill monkeys for food and trap many primates for sale as pets, research animals, and zoo specimens. Some animal species may move into human communities when their own are destroyed.   Affects of extinction - The extinction of endangered and other species will result in the following consequences. They are - Disturbed ecosystem. - Extinction of other related and based species of it. - Imbalance of nature activities. - It may even lead to extinction of human population in coming generations.
