Cool down + discharge + reservoir Sample article: Water pollution There are several types of pollution. However, water pollution is the most serious in our area. It is caused by several factors. Firstly, families dump sewage into the river. In the past it was a very beautiful river, but now the water is almost black. Secondly, there are two new factories in our area, and they are dumping chemical waste into the lake and river. Thirdly, pesticides are another source of pollution. Farmers in our area usually use these to kill insects. Water pollution badly affects our area. We do not have enough fresh waster to water the plants and crops. People cannot raise fish in the river and the lake because the water there is so polluted. In addition, there are no more wild ducks near the river today since they cannot find fish for food. Another negative effect is that sometimes in the afternoon there is a bad smell from the polluted river, so people do not like walking along it anymore. People in our area al aware of this problem, and we are thinking of ways to solve it. Audio script: Reporter:Does thermal pollution mean that bodies of water get hotter, Mr Nam? Mr Nam:Not always. Sometimes the water becomes colder, and that’s thermal pollution. In general, thermal pollution means a change in the water temperature. Reporter: That’s interesting! What causes it? Mr Nam: Power stations are factor. They use water in the nearby lakes or rivers to cool their equipment, which heats up the water. Then they dump the hot water back into its source. Reporter: Are there any other causes? Mr Nam: Yes. Thermal pollution may also happen due to the discharge of cold water from reservoirs into warm rivers. Reporter: Thermal pollution can have dramatic effects. Right? Mr Nam: Certainly. Most aquatic creatures need a certain temperature to survive. Warmer water has less oxygen in it, and this can harm fish populations. Beside, warmer water can cause harmful algal blooms. This can change the colour of the water like in the first picture and more seriously, the algae poisons the fish. Reporter: What can we do, Mr Nam? Mr Nam: In many places, they build cooling towers like in the second picture to cool down the water from power stations. Reporter: Anything else we can do? …
