In three sentences or less explain why predicting our future oil supply is controversial and involves some uncertainty.

Explanation:

Oil is a nonrenewable resource that takes billions of years to develop. While new oil is being discovered, with the help of new technology, the amount of oil being used up far exceeds the amount of new oil that is being discovered. For example, in 2000 to 2005, the world consumed nine times more oil than was discovered in the same amount of time. Predicting future oil supply is a hard thing to do, because we’re just not sure how much more oil can be extracted or if the reliance on this fossil fuel will go up, down, or remain unchanged. What we do know, is that there is not an unlimited supply of oil, since it takes billions of years to form and that it is wreaking havoc on our planet.
