by heatfeed

There have been many terrestrial, avian, and marine animal species that have gone extinct due to human influences. It has been reported that a study has discovered that by the year 2020, more than two-thirds of all wildlife population could be wiped out if suitable action isn’t taken.

The study, done by the World Wildlife Fund and the Zoological Society of London, is called the Living Planet Index. The study states that since 1970, there has already been a 58% loss of wildlife species especially marine and avian species. 

Culprits of this Phenomenon

The major culprits of this phenomenon are poaching and illegal hunting and trading of animals, climate change, deforestation that leads to loss of their natural habitat, and pollution of air and water bodies.
