The Sixth Mass Extinction: True or False?

It is believed Earth may be in the midst of another(prenominal) passel extinction, also known as ?The Sixth bunch quenching?. This kettle of fish extinction is the first for 65 gazillion years since the Cretaceous-Tertiary period. Its the adjapenny annihilation of vast numbers fete of species. It is casualty now, and we, the human race, argon its cause? (Leakey, 1995). Every year, between 17,000 and 100,000 species vaporize from our planet, which will result in fifty per cent of the Earths species vanishing within the future(a) 100 years. What is the cause of such extensive numbers of species vanishing??Deforestation?Spreading agriculture?Pollution: dodo fuels, nursery gases, CO2 = global warming & humor tack?Population increasing vastly?Overexploitation of species and indispensable resources? encroaching(a) species eg. Gorse in New ZealandRecords suggest that the worst mickle extinctions can advance when temperatures be the warmest. By comparing previous(pr edicate) originate ins of marine and terrestrial diversity with prehistorical temperature estimates, researchers from the Universities of York and Leeds found a close relationship between Earths climate and extinctions over the ancient 520 million years. The result: higher extinction rates emit at higher temperatures. Due to fossil fuels and greenhouse gases emitted by everyday human activity, earth is gradually warming up, which could soaked the end of a number of different species. ?Temperatures forecasted over the next century argon within the range of the warmest greenhouse phases that atomic number 18 associated with rush extinction events identified in the fossil render (Jenkins, 2007). Four of the five past mass extinction events are related with warm greenhouse phases. During the End-Permian extinction event, the largest of all mass extinctions, 95 percent of animal and plant species were destroyed, which occurred through sense experience of the warmest-ever clima te phases. If global warming increases, whic! h is very likely, our planet could induce extreme threats against our species. Population increase is also...
