Report: Earth Heading for Point of No Return

Humans are using up Earth’s resources much faster than they can be renewed—it takes the Earth 1.5 years to make up for what we use in just one year, according to a disturbing new report from the World Wildlife Fund. Last year, humans went through the full year’s worth of renewable resources by Sept. 27. The report also finds that biodiversity, or the number of plant and animal species and other organisms, has dropped 30% in the past four decades.

Humans are "emptying the fridge, we're not really taking care of the lawn, we're not weeding the flower beds and we're certainly not taking out the garbage," says a WWF director. The countries using up the most resources per capita? Qatar, Kuwait, United Arab Emirates, Denmark, and then the US in spot No. 5. LiveScience has the full top 10, along with those countries that use the least. (More biodiversity stories.)
