Unless action is taken immediately, there is a good chance that all the oceans of the world will be dead by the year 2010.How can this possibly happen??

We have already seen that people allow all sorts of waste products to flow into the sea. It is almost impossible to measure how much waste water and industrial waste end up in our oceans, but we can find out how much oil is poured into them legally and illegally. It is illegal to pour oil into the sea close to the shore, but when a ship is many miles out to sea there are no such rules. Scientists have different ideas as to the amount of oil put into the sea, but the lowest figure for oil poured in European waters alone is nearly 200 000 tons every year. Some people say the figure could be ten times as high.?

It is not only our coasts that suffer from oil pollution. Among other things, many shell fish(creatures which live in water),and have a hard shell—oysters and mussels, for example—now have high amounts of poisonous substances. Next time you have shell fish to eat, how can you be sure that they are free from oil pollution? You cannot see the effects and you cannot taste them, either. It is really quite a problem.?
