"SAO PAULO - Setting aside an additional 1.2% of the world's land as nature preserves would prevent the majority of predicted plant and animal extinctions and cost about $263 billion, according to a study published on Tuesday.
The world is racing to meet a goal to protect 30% of the world by 2030 to protect wildlife that is being decimated by climate change, pollution and habitat destruction.
Global policymakers will meet at a United Nations summit in Colombia in October to discuss plans for reaching that goal.
The study in the journal Frontiers in Science aimed to identify the highest value areas in hope that they be included in those protection plans, said Carlos Peres, a study co-author and conservation ecology expert at the University of East Anglia in the United Kingdom.
"Most countries do not actually have a strategy," Peres said."
