I wish I had seen that rant (I take it you posted it via YouTube?). Sad, people are too engrossed in their shallow television sets, the cost of gas, and office politics to truly be concerned, and those who do take action are, in majority, pseudo-hippies who mostly do little than complain and rant on the PETA website.
Just imagine the dying ecosystems decades from now and the havoc the blazing heat (that is to say, famine) and the ensuing rising of waters, cascading into massive flooding. Need I mention the change in the current belt (due to warming of the ocean waters, waters that flow in a distinct cycle of drifting coasts and seas) that could easily cascade into world-wide catastrophe?
Nuclear power has so much potential, as does solar energy. The problem is the lack of energy-friendly power plants, nor any real fiscal initiative to build them.
