The Very Crude Awakening!
Look at this scary chart and see how we use the production of oil.
This graph explains that we use a lot of oil. What will we use in the future if we run out of oil??? Some scientists designed a car that runs on compressed air, called the Minicat! This is one clean machine - actually the cleanest in the world! The problem would be that they would cost so much, few people could buy them. There are countries that form an oil production organization called OPEC that controls most of the supply of pumping from their oil fields. The country that has the most, at 65%, is oil fronteir, Saudi Arabia! Some other issues with oil is that the country of Iraq attacked Kuwait for the oil, creating the Persian Gulf War.
