Water is probably one of the most important resources we have. It takes up 70% of the Earth's surface and the body is also made up of 70% water.

It takes up 70% of the Earth's surface and the body is also made up of 70% water. Scientists know more about space than they do about what lurks beneath the dark surfaces of the oceans. Humans need water to survive; to drink, wash and grow our food. But despite our dependence on water, we pollute it with oil, litter and chemicals. This piece of writing will explain the significance of water, the source of this pollution, the significance water pollution has on the environment and how we can try to stop it. We can find water almost everywhere. The table on the right shows us where water can be found. We can find water in the oceans, icecaps, glaciers, ground, lakes, inland seas, soil, the atmosphere and rivers. The largest source of water is the oceans which takes 97.24% of the world's total water volume. But just because we can find water easily, it doesn't mean it is suitable for human use. ...read more.


Oil spills have in the past and present received much media attention. The Sea Express in 1996 released 72,000 tonnes of crude oil into Milford Haven in South Wales. The Braer in 1993 split its 85,000 tonnes of crude oil into the water bodies of the Shetlands Islands. Many more other spills before and after these have happened. I will talk of the Exxon Valdez in more detail. The Exxon Valdez The Exxon Valdez was one of the first of its kind to carry oil across oceans. It was a large vessel which could carry 1.48 million barrels of crude oil per voyage. The Exxon Valdez struck Bligh Reef in Alaska on March 24th 1989, when oil started to leak out of its hull. After only three and a quarter hours, 5.8 million gallons of oil was released into the Prince William Sound. It was estimated that 11 million gallons of crude oil was finally released across the 1,300 miles of coastline. The water became black and disabled or killed most animal life. The initial clean up took three years to complete and an amazing $2.1 billion. A technique used to clean the oil was by using oil booms. The picture to the left shows how it is done. The booms consisted of three boats. ...read more.


Hundreds of people die each year from drinking this contaminated water. What can we do to clean water pollution? There are many things we can do to clean up our water, but the best way is to prevent it from happening in the first place. Unfortunately, there will sometimes be accidents that happen, which will create water pollution, but then we can help clean it up. With oil, we can wait for it to naturally disperse, with help from the weather (such as waves and high winds) or we can do the various techniques mentions under the Exxon Valdez. The government has also put more money in over the last couple of decades to improve the cleanness of the water. What is being done to prevent water pollution? In many countries, the dumping of waste and sewage is banned, but there are still several out there who have not taken up this ban yet. The laws for agricultural pollution have changed. A water pollution offence can lead to a maximum fine of �20,000 in a magistrate's court, or even more severe sentences in the higher courts. Conclusion I have learnt from doing this piece on water pollution the importance of water in our everyday life and the amount of pollution there is. Water pollution is still a major problem in many parts of the world, and I think there should be more done to help stop and prevent it from happening.
