the westerners had release 90% of the carbon into the atmosphere for the last 200 years...now they called for green eartg..the west should bear 90% of the cost to restore the earth.........that is fairness.......... People in africa continent dont even contribute a few % of the carbon emission..is it fair to ask then to cut down usage in equal propotion as the west......again..white man hyprocricy!!!!!!!!!!!!!!
