A new World Wildlife Fund report says wildlife populations have declined by 58 percent since 1970.
Based on the current data, Living Planet projects that the loss in wildlife population could reach two-thirds of the 1970 levels by 2020.
Poaching, overfishing, and of course climate change are contributing to the loss of wildlife.
However, there’s still not a consensus on how to address climate change, and some people can't even accept it as a reality.
Exploitation of fresh water sources and increasing rates of pollution are also having negative impacts on animal populations.
