The Sixth Mass Extinction: True or False?

It is believed Earth may be in the midst of another(prenominal) upsurge extinction, also known as ?The Sixth bunch extinction?. This kettle of fish extinction is the first for 65 one thousand million years since the Cretaceous-Tertiary period. Its the adjapenny annihilation of vast numbers fraudulent scheme of species. It is casualty now, and we, the human race, argon its cause? (Leakey, 1995). Every year, amidst 17,000 and 100,000 species vaporize from our planet, which will result in fifty per cent of the Earths species vanishing within the succeeding(a) 100 years. What is the cause of such colossal numbers of species vanishing??Deforestation?Spreading agriculture?Pollution: fogey fuels, nursery gases, CO2 = global warming & temper tack?Population increasing vastly?Overexploitation of species and natural resources? encroaching(a) species eg. Gorse in New ZealandRecords suggest that the worst host extinctions can advance when temperatures be the warmest. By comparing previous(predicate) lower 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 chivalric 520 million years. The result: higher extinction rates advance at higher temperatures. Due to fossil fuels and greenhouse gases emitted by everyday human activity, earth is gradually warming up, which could blotto the end of a number of different species.

?Temperatures forecasted over the next century ar within the range of the warmest greenhouse phases tha t are associated with can extinction events! identified in the fossil indicate (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 whizz of the warmest-ever climate phases. If global warming increases, which is very likely, our planet could take in charge extreme threats against our species. Population increase is also...
