The World Wildlife Fund (WWF) in its report Living Planet Report 2012 released on 15 May 2012 noted that Biodiversity has decreased by an average of 28 percent globally since 1970 and the world would have to be 50 percent bigger to have enough land and forests to provide for current levels of consumption and carbon emissions.
The report further added that unless the world addresses the problem, by 2030 even two planet Earths would not be enough to sustain human activity. The WWF also urged the global community to take the issue of environmental degradation seriously.
A summit on the global environment is to be held in the Brazilian city Rio De Janerio from 20 to 22 June 2012. The summit is expected to draw more than 50,000 participants from different nations. Politicians in the summit will be under tremendous pressure from environmentalists to agree goals for sustainable development, in the spirit of the Rio Earth Summit that spawned the Kyoto Protocol 20 years ago.
