Humans are using resources at such a pace they need another world to meet demand for land to grow crops and forests and raise animals, WWF International said.
People required 18.2 billion hectares (45 billion acres) of land by 2008, with 12 billion productive hectares available, WWF said today in its biennial Living Planet report. About 55 percent of land needed was for forest to absorb carbon dioxide emissions. The Earth takes one and a half years to regenerate natural resources used annually by human inhabitants, WWF said.
