The issue of climate change is one that we ignore at our own peril. There may still be disputes about exactly how much we're contributing to the warming of the earth's atmosphere and how much is naturally occurring, but what we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return. And unless we free ourselves from a dependence on these fossil fuels and chart a new course on energy in this country, we are condemning future generations to global catastrophe.
As President, I'll invest in renewable energies like wind power, solar power, and the next generation of homegrown biofuels. That's how America is going to free itself from our dependence on foreign oil Â– not through short-term gimmicks, but through a real, long-term commitment to transform our energy sector.
