ENDANGERED SPECIES Introduction An endangered species is a population of organisms which is at risk of becoming extinct because it is either few in numbers‚ or threatened by changing environmental or predation parameters. The International Union for Conservation of Nature (IUCN) has calculated the percentage of endangered species as 40 percent of all organisms based on the sample of species that have been evaluated through 2006.Many nations have laws offering protection to

There are an estimated 5-10 million species that exist currently and only 1.5 million have been identified (Sherry‚ 2). Scientists classify species into six different groups: plants‚ animals‚ insects‚ algae‚ fungi‚ and microorganisms (Today’s Situation). In the tropical rainforest alone‚ most species are disappearing at the rate of 1% a year (Sherry‚ 6). If the current trend continues‚ at least

LOSES OF BIODIVERSITY Some species that are more vulnerable to extinction than others include species at the top of food chains‚ such as large carnivores. Endemic local species which is a species found in only one geographical area with a very limited distribution‚ species with chronically small populations‚ migratory species‚ species with exceptionally complex life cycles and specialist species with very narrow requirements are also the examples species that are more vulnerable to extinction
