Wild animals count could fall 67% from 1970-2020: Study
The number of wild animals across the world could fall by 67% in the fifty years to 2020, according to a study by World Wildlife Fund (WWF). It attributed the fall in animal numbers to the destruction of forested areas and pollution. WWF researchers reportedly monitored the changing presence of 14,152 populations of the 3,706 vertebrate species to draw conclusions.
