We have all learned a lot about air pollution sinceMr. Wang's geography lesson last week. But today, let's talk about water pollution. First of all, people have put lots of unclean things into rivers and lakes, such as wastewater and rubbish. Such actions have reduced the quality of our drinking water. Besides, farming and factory activities have also been the main causes of water pollution. For many years, farms and factories have poured harmful materials and waste into rivers. As a result, the natural environment has suffered greatly. What's worse, oil pollution from ships and land-based factories is also serious. It has polluted the ocean and harmed plants and animals as well. In a word, water pollution has become a great danger to human health and the environment. We need to reconsider our way of living and protect our home planet. Activity 2 【环保检察官的取证本】 请根据课文，提取出英文原句! 这些原句正是 要填进课本空格的答案， 直接对接课本!
