Global warming problem is greater than any one person, city, state or nation. It affects the Earth as a whole. Thus, the fundamental problem is us, the people. But we are also the solution.

Over the years I have realized that no technology can solve this problem. Technology only follows our lead. So the only true solution is to change our mind set. This is the GREATEST CHALLENGE OF MANKIND.

Hydrogen is not going to "truly" here till 2050; if we think we cav wait that long we are sadly mistaken. Ethanol and biofuels: a lot of pollution comes from fertilizer runoff and quite a few starving people would like to eat corn. When you factor in economics, many of these fuels just can't compete with gasoline.

Few understand the scale of this problem and how it affects every aspect of our life. The solution requires a radical change in the universal principals of mankind. No matter how try to solve this problem, it will radically affect our economy. But the cost of doing nothing will be far greater.

Basically, we, the people, are the core of the problem and a balance must between the economy and the environment must be reached.
