Al Gore is not promoting cleaner air and correcting global warming for the interest of preserving the world.
WMD warfare is more of an immediate threat than pollutions from factories. Why isn't he fighting a cause to eliminate nukes? All anyone has to do is push a button and we are all gonners. How many countries have the capacity to blow up this planet? Think abou that! But what is Gore doing? He's promoting to get huge profits from his own stock! Fact is, Global warming is the least of our threats or worries.
