The endangered anmial-Mouse Lemur and White-flag Dolphin Essay

The endangered anmial-Mouse Lemur and White-flag Dolphin - Essay Example Conservation programs are being developed carried out to ensure the continued existence of these fascinating animals. This essay presents a comprehensive description and current circumstances of these two endangered animals. Introduction Extinction naturally happens. In fact, a huge number of species has already died out. With regards to this, several individuals and groups have explained the worsening global scarcity of species by declaring that because extinction naturally occurs, the extinction of recent species is merely an extension of a natural occurrence. The 1973 Endangered Species Act (ESA) was the first official, federal attempt to recognize that every species serves a distinctive, special function in the environment and that people, especially governments, should keep from disturbing the balance of nature or the ecosystem (Liebesman & Petersen, 2003, 89). The double responsibility for stable and organized management of the ESA is assigned to the Fish and Wildlife Service ( FWS) for land and several marine species and the National Marine Fisheries Service (NMFS) for marine life forms. The Act’s original goal was â€Å"to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved† (Liebesman & Petersen, 2003, 89). ... From the point of view of ecology, a more effective method is to focus on protecting self-sufficient environment of these species, and allowing nature do its part (Liebesman & Petersen, 2003, 89-90). The FWS is tasked to list, delist, and reclassify protected species. When it is suggested to list a species as Endangered or Threatened, the FWS publicizes the suggestion in the U.S. government’s publication—the Federal Register (Baur & Irvin, 2010, 1). Afterward the FWS makes a decision whether to endorse, modify, or reject the suggestion. A species can be classified either ‘threatened’ or ‘endangered’, which depends on its condition and the level of threat. By definition, a ‘threatened’ species is â€Å"likely to become endangered in the foreseeable future throughout all or a significant portion of its range† (Baur & Irvin, 2010, 34), whereas an ‘endangered’ species is â€Å"in danger of extinction throughout all or a significant portion of its range† (Baur & Irvin, 2010, 34). A species is listed as endangered or threatened due to any of these reasons (Liebesman & Petersen, 2003, 18-20): (1) the threatened or current disruption or devastation, alteration, shortening of its range, or weakening of its habitat; (2) overexploitation for scientific, business-related, or recreational purposes; (3) the incompetence of current regulatory measures; (4) disease; and (5) other human-made or natural phenomena affecting its ability to survive. Once a species is listed, protective measures begin. Such measures involve protection from damaging impact of government programs or operations; limitations on the capturing and selling of species; and execution of recovery plans. These attempts strengthen the survival
