They should also be punished for creating pollution. Finally, everybody is affected by global warming. Therefore, it is important that governm
15、ents involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of
16、 saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy. In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet. 3分钟关于全球变暖的英语演讲稿3 globa
