Are you for it or against it? Now lets work in groups of four and discuss the reasons for and against banning whaling. While the Ss are having discussion, walk around to see if they are getting on well with the job. When they have finished, ask the Ss to speak out their groups opinions and reasons. Possible discussion: Sa: I think its important to protect whales. After a long time hunting, the number of whales has largely decreased. On the other hand, with the development of industry, the sea has been seriously polluted and the pollution has killed many whales.Sb: Yes. I agree on the international ban. Whale is one of the oldest species on the earth. Protecting them effectively and studying them seriously will bring human beings great benefit. Sc: Whales are the hugest animals living in the ocean. The number of them in nature will have great effect on the balance of sea animals as well as nature.Sd: We seem to have the same idea about the topic and I agree with you all. Firstly, animals are human beings friends; we must try to protect them, especially those endangered. It is reported that many whales kill themselves for some unknown reasons on some beaches every year. Maybe that is caused by pollution. In a word, man has done much harm to whales. Its time for us humans to do something to protect them. No more whaling!T: Yes, no more whaling! I agree with you very much! I hope you can get more information about whales after class to learn more about their current situation.
