The World Wildlife Fund has released their Living Planet Report today, and the news isn’t good. According to the WWF’s findings, demand on natural resources has doubled since 1966. Today, the global community is currently using the equivalent of 1.5 planets’ worth of resources, and it takes the earth a year and a half to regenerate the natural resources that people consume in a single year.

“We are living as if we have an extra planet at our disposal. We are using 50 per cent more resources that the Earth can sustainably produce and unless we change course, that number will grow fast — by 2030 even two planets will not be enough,” said Jim Leape, WWF’s Director General, in a statement.

The report also found that biodiversity is still being lost, and high-income countries have five times the ecological footprint than their low-income counterparts: the U.S. leaves the fifth largest footprint out of the 130 countries included in the report, while Canada follows at eighth.

But all is not lost. These dark tidings can be reversed if we start making better choices, the report explains. The WWF recommends more protection for natural capital and biodiversity, more efficient production systems, a better pattern of consumption, redirected financial flows that support conservation over consumption, and equitable resource governance.

The WWF has released the report in the lead-up to the Rio+20 UN Conference on Sustainable Development, which will kick off in Rio de Janeiro five weeks from now.
