World’s vertebrate population cut in half since the 1970’s

The number of wild vertebrates has been cut in half since the 1970s while the world’s human population has doubled, according to a study by the World Wildlife Fund. Some of the biggest declines are among forest elephants in west and central Africa, whose population has dropped 60% since 2002, in great part due to poaching.
