The WWF released the 2014 Living Planet Report citing a 52% decline of wildlife between 1970 and 2010, “a much bigger decrease than has been reported previously.”
Latin America's 83% decline of animal loss is found in many of its low-income countries. Marine species, especially in the tropics and in the oceans surrounding Antarctica, have suffered a 39% loss.
The half of the world's wildlife phrase isn't applicable to all the countries in the world. In fact, in countries whose incomes are high have seen a 10% increase of biodiversity was shown.
Collecting data and comparing worldwide statistics is no easy task. One thing researchers noticed is that loss was higher than earlier predicted, making all present and future conservation efforts more vital. Why not see how you can help out here?
