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 water 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 7
