Water pollution

Water is essential for life . Without it , life on Earth would not exist. However, although we know this for a fact, we keep polluting the water on our planet.

One of the main causes of water pollution is waste which is pumped into rivers, lakes, and seas. The waste comes from homes, factories and farms. Some of this waste can harm people, animals and plants, while other waste causes disease. Scientists predict that most of the world’s rivers will be polluted in twenty years’ time and they say that some rivers are already so polluted that they are biologically dead.

Another main cause of water pollution is oil spills. Oil spills are caused by leaks in ships or by accidents involving oil tankers. Thousands of tons of oil spread over the surface of the sea, and as a result destroy marine life, life on beaches, kill sea birds, etc.

A lot of measures have been taken by governments to stop water pollution. For example, the people responsible are fined. However, the problem is very serious and something must be done to prevent water pollution. Cleaning up rivers or oil spills can be extremely difficult, expensive and time-consuming.

3. Post- reading activity. Answer the questions

1. How does waste  get into rivers?
2. Why is waste dangerous?
3. What do scientists predict?
4. What causes of oil spills?
5. How do oil spills harm the environment?
6. Why is it better to prevent water pollution than clean it up?

4. Now we’re going to make an experiment and then you should take into consideration the result of this experiment to make the conclusion.

You will need:

• A glass of water( half full)
• A few drops of car engine oil
• Some cotton wool
• Some washing up liquid

1. Rub unpolluted water between your fingers. Remember what this feels like.
2. Add a few drops of car engine oil to the water. This is your ‘water pollution’.
3. Use the cotton wool to try and get the oil out of the water. This is your ‘clean-up’ operation.
4. Rub the water between your fingers again. Notice that the water is still oily. Not all the oil can be removed. Just imagine what it’s like in the sea with waves!
5. Add washing –up liquid until the water doesn’t feel oily. You will need to add quite a lot! Now the water isn’t very oily but it’s full of soap, which is also harmful.

What did you learn?

( It’s much better to prevent pollution than to try and clean it up afterwards.)
