Unit 4 Global warming
导读：很多科学家认为全球变暖是由人类活动造成的，由于人们焚烧化石矿物或砍伐并焚烧森林，产生了二氧化碳等多种温室气体，导致全球气候变暖。因此，我们究竟应该为此做些什么呢？
Task：What can we do to protect the earth from being
bad to worse?
Global warming is a growing problem in the world. Melting ice－caps in the Arctic and Antarctica, rising temperatures across the continents, increasing number of typhoons and tropical storms are just some of the effects of global warming.
It must be realised that humans activities are the causes of global warming. It is therefore our duty to save the earth. We can begin by minimizing the amount of carbon dioxide by taking public transport instead of driving and using energy－efficient electrical appliances. Besides, the government can probably limit
the number of cars allowed on the roads by imposing fines on offenders and improving public transport systems. More trees can be planted too. Education to protect the environment should also be planned. Countries around the world can hold meetings and conferences and decide the steps to take to limit the CO2 levels. Economic sanctions can also be imposed on countries that have violated the rules. The Kyoto Protocol is one such example.
It is important to cure the world, for the sake of ourselves and our descendants. We have to take action now.
