Rio + 20: some considerations

Biodiversity on the planet had an average reduction of 28 percent since 1970, and the world would be 50 percent more to offer land and forestry resources needed to sustain current levels of consumption and carbon emissions, said the WWF environmentalist on Tuesday.

The Rio + 20-name that alludes to the 20 years of the environmental conference in Rio-92-should attract more than 50 thousand participants between 20 and 22 June. Politicians are under pressure from environmentalists to accept targets for sustainable development, in the spirit of the first Conference in Rio, which then led to the creation of the Kyoto Protocol.

Although the goal of that Treaty were to contain global warming, global carbon emissions have continued to grow by putting the world in the way of a "catastrophic increase" by the end of the century, according to WWF.

Leape said that one cannot "underestimate the inertia of the system", because a century ago the economy is based on the use of fossil fuels and on the premise that the planet's natural resources were not exhausted.

"You see this notably in the case of oceans, where we have collected fish like there is no tomorrow, as if the fish were always being there," he said.

So it is very important that we are all alert to help our planet.Each one of us prevent abuse and waste of natural resources.
