major problem is that oil is very dirty. Oil burning leads to the release of gases that pollute the\renvironment. Problems resulting from this include global warming and health concerns for people.\rOil drilling also causes environmental problems, as oil coming up to the surface of the ground\rspills into the surrounding land.\rA second major problem is that oil transportation is dangerous to wildlife. Oil spills, possible\rwhen we transport oil by ship, are extremely deadly to marine life.\rAnd a third major problem is that oil is limited. Since oil takes millions of years to form, and since\rwe are using a lot of it, we will eventually run out. When that day comes, the world will be in real\rtrouble. Thus, it's better to develop new methods for generating energy now.
