STUDY FINDS HUMAN IMPACT ON WORLD'S PROTECTED AREAS "SHOCKING"
One-third of the world's protected lands are being degraded by human activities and are not fit for their purpose, according to a new study in the journal Science. Global efforts to care for natural heritage by creating protected zones have, in general, been a huge conservation success story. Since the Convention on Biological Diversity was ratified in 1992, the areas under protection have doubled in size and now amount to almost 15% of the lands and 8% of the oceans. But researchers now say that roads, mines, and cities are spilling into these protected areas without restriction. "What we have shown is that six million sq km have this level of human influence that is harmful to the species they are trying to protect," the study's senior author, Prof James Watson from the University of Queensland and the Wildlife Conservation Society, told the BBC's Science in Action program.
