Studies Say We Are In The Sixth Mass Extinction In History
The latest report from World Wildlife Fund’s Living Planet Index revealed that since 1970, the number of mammals, fish, birds and reptiles has dropped overall by 58 per cent worldwide.
If accurate, it means that the world’s wildlife is disappearing at an overall rate of 2 per cent every year. Globally, between 1970 and 2012, 38 per cent of the terrestrial population, 81 per cent of freshwater population and 36 per cent of the marine population has declined.
As per the report, about 41 per cent of the mammals, 46 per cent reptiles, 57 per cent amphibians and 70 per cent freshwater fish are “threatened with extinction” in India. Four of the 385 species of mammals are already extinct in India. Seven per cent of birds may also be extinct around the world. By 2050, there will be more polythene in the ocean than fish.
The population of the planet has grown from about 1.6 billion people in 1900 to 7.3 billion today. The report says:
By 2012, the bio-capacity equivalent of 1.6 Earths was needed to provide the natural resources and services humanity consumed in that year.
According to the researchers, this time in history can be called ‘Anthropocene’. In Anthropocene, the climate changes, oceans acidify and the entire community of flora and fauna vanishes within a single human lifetime.
Speaking to CNN, WWF conversation scientist Martin Taylor said:
We are in the sixth mass extinction and this is definitely a human impact. There have been only 5 mass extinction before this and we are definitely approaching towards the sixth.
