Oil is essential for modern life-apart from its use in transportation, it is also used in making fertilizers,plastics,and many other products.About 64 percent of the world's oil is located in the Middle East,but the heaviest consumers of oil are Europe,America,and Japan. The problem lies in getting the oil from the countries that produce it to the countries that consume it. This is mainly done using oil tankers. There are roughly 4000 oil tankers in use today,and every day more than 100million tons of oil is shipped. Usually this oil is shipped safely and with no problems,but occasionally there is a disaster.
