Rio+20 can be used as a depth sounder. If we compare how clean / dirty the air was say 20 years ago to how it is today we will have at least one indicator of the environments general direction.
‘WHEN the 1992 Earth Summit took place in Rio de Janeiro, Brazil two decades ago, atmospheric carbon dioxide concentrations were 357 parts per million (ppm). As the recent summit, dubbed “Rio+20” Conference, was remembered in the same city from June 20-22, concentrations averaged at 395ppm, and even reached 400ppm in the Arctic. Perhaps this is an early indication that over the last 20 years things have not lived up to expectations even though the 1992 event was marked by the largest gathering of heads of state.’
We see the goals of UNCSD Rio+20, the “Green Economy” and its premise that the world can only “save” nature by commodifying its life giving and life sustaining capacities as a continuation of the colonialism that Indigenous Peoples and our Mother Earth have faced and resisted for 520 years. The “Green Economy” promises to eradicate poverty but in fact will only favor and respond to multinational enterprises and capitalism. It is a continuation of a global economy based upon fossil fuels, the destruction of the environment by exploiting nature through extractive industries such as mining, oil exploration and production, intensive mono-culture agriculture, and other capitalist investments. All of these efforts are directed toward profit and the accumulation of capital by the few.’
