报告：野生动物自1970年以来减少近60%

Wildlife populations across the globe have dropped nearly 60 percent since 1970 and human activity is to blame, according to a report released by conservation groups.

The joint report produced by the World Wildlife Fund and the Zoological Society of London warned that if the current trends continue, the decline in world populations of mammals, birds, fish, amphibians and reptiles could reach two-thirds by 2020, an annual loss of about two percent.

"Wildlife is disappearing within our lifetimes at an uNPRecedented rate," said Marco Lambertini, director general of WWF International.

According to the report, the drastic reduction in wildlife populations can be directly attributed to human development. A growing human population, which has more than doubled since 1960 to around 7.4 billion, means less room and food for other animals and could push them out of existence if changes aren't made.
