Many people believe that human activity is causing the earths temperature to rise。 They say that this global warming will have dreadful consequences for our environment， such as drought and flooding。

　　What should governments do to help prevent global warming？ Give reasons for your suggestions。

　　The earths temperature is rapidly changing。 As a result there has been a lot of climate change such as heat waves， droughts and floods。 Scientists believe that this is the result of human activity， which is polluting the Earths atmosphere。 This could become a disaster if governments do not act to help prevent global warming。 They can act in three ways; by supporting research， by making laws and by keeping the general public informed。

　　Firstly， governments can support research。 For example， they should encourage companies to develop vehicles that cause less pollution。 They should also support alternative sources of electricity from wind and water rather than from oil and coal。 As well， they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem。

　　Secondly， they should make laws that limit the amount of greenhouse gases that companies can emit。 Private companies should be rewarded for following these laws。 They should also be punished for creating pollution。

　　Finally， everybody is affected by global warming。 Therefore， it is important that governments 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 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。

　　Nowadays we are producing more and more rubbish。 Why do you think this is happening？ What can governments do to help reduce the amount of rubbish produced？

　　I think it is true that in almost every country today each household and family produces a large amount of waste every week。 Most of this rubbish comes from the packaging from the things we buy， such as processed food。 But even if we buy fresh food without packaging， we still produce rubbish from the plastic bags used everywhere to carry shopping home。

　　The reason why we have so much packaging is that we consume so much more on a daily basis than families did in the past。 Convenience is also very important in modern life， so we buy packaged or canned food that can be transported from long distances and stored until we need it， first in the supermarket， and then at home。

　　However， the amount of waste produced is also a result of our tendency to use something once and throw it away。 We forget that even the cheapest plastic bag has used up valuable resources and energy to produce。 We also forget that it is a source of pollution and difficult to dispose of。

　　I think， therefore， that governments need to raise this awareness in the general public。 Children can be educated about environmental issues at school， but adults need to take action。 Governments can encourage such action by putting taxes on packaging， such as plastic bags， by providing recycling services and by fining households and shops that do not attempt to recycle their waste。

　　With the political will， such measures could really reduce the amount of rubbish we produce。 Certainly nobody wants to see our resources used up and our planet poisoned by waste。
