Question
Since the origin of life on Earth, there were five episodes of mass extinction of species.
Who is mainly responsible for the 'Sixth Extinction’?
Solution
They are extinctions abetted by human activities such as settlements, hunting, overexploitation and habitat destruction. Colonisation of tropical Pacific islands by humans has resulted in the extinction of more than 2000 species of native birds. During the last 500 years, the Earth has lost some 784 species (IUCN, 2004). It includes 338 vertebrates, 359 invertebrates and 87 plants. Amphibians seem to be at higher risk of extinction.
