I don't want to be a pesimist but I can't help it. I think from the beginning of time when people first came into being on this planet, it has been survival. Now here we are milleniums further down the road and what is happening? Wars, global warming, famines, disease. You name it we have it coming. Why? We have too many people on this planet and are stressing it beyond comprehension. Do you honestly think we won't drill in the Alaska Wildlife Refuge? Think again. People have no conscience under shitty governments and administrations... sorry!
I have a larger view and one that's probably going to take place whether we as people do anything to change our current crisis or not. I don't think that our situation is reversible at the current rate of growth in this world. I think larger forces of nature will decrease world populations substantially as well as wars.
We are in a world of hurt here and I don't think our government wants to change it's policy at all. Let's just burn up all of the oil worldwide, and we'll drink sea water since it will be so diluted with all of the melted ice from the ice caps and glaciers. Stupid humans! We're all guilty from the food we buy to the cars we drive. We're an obese world literally.
