Oil

Did you know Brazil can function well even without foreign oil?  They have cars that can run on sugarcane ethanol.  If there were a situation that prevented the import of any oil, like, oh say, we run out of this "unlimited" fossil fuel, Brazil would not flinch.  I'm calling the U.S. out on this.  Why?  Why can't we develop technology that will make our economy and security that much stronger.  We will be independent and keep the earth healthy.  We won't have to unnecessarily kiss the middle east's ass.

Oil is not unlimited.  The world will run out soon enough.  Maybe that will be the only thing that keeps people from driving.  Also, we could just stop using plastic bags in supermarkets.  It takes oil just to make those bags that people throw away after they buy their grocery.  Switch to cloth bags that you can reuse again and again.
