How will we safe our nature, natural environments and how is it possible?

U said it yourself we need human co-operation of an unprecedented magnitude. The leaders of our countries, our world leaders, need to stop this retarded debate of if there is really a greenhouse effect or not. THERE Definitely is, u might think im a nut, but 12/21/2012 is gonna be a day of reckoning like it or not. We will probably be visited by extra terrestrials who will vanquish the uncaring masses. They will once again modify the dna of the survivors and a new race will be born. It's probably too late to show a huge movement of the world of taking care of and repairing the earth. They have visited us and directed our paths in the past in fact the last major intervention was marked with the origin of christianity and islam. Perhaps they are coming back now to decide the victor????
