　　no one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. according to many experts, even greater impacts are still on the way.

　　there are numerous causes for this problem. on one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. on the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.

　　it is urgent that immediate and effective actions should be taken right away. first, more trees need to be planted to help improve and beautify the environment. besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. in a word, there is a long way to go before we can take a comfortable world for granted again .

　　many people believe that human activity is causing the earth’s temperature to rise. they say that this global warming will have dreadful consequences for our environment, such as drought and flooding. m

　　what should governments do to help prevent global warming? give reasons for your suggestions.

　　the earth’s 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 earth’s 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.

　　there is little doubt that the planet is warming. over the last century, the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius). the warmest since the mid 1800?ˉs was the 1990s. the hottest years recorded were 1997, 1998, 20xx, 20xx, 20xx. the united nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century?ˉs end - enough to have the polar caps all but melted.if the ice caps melt, a vast majority of our countries borders will be under water. monuments and great buildings, as well as homes and lives will be under water, including new york city. so now we know what some of the causes are for global warming, how can we as individuals do our part to help save the planet? the answer is simpler than you may think. you don?ˉt have to go miles away from home to protest, or spend masses of money. if you try to follow the few simple steps that i shall now give you, you will have started to help us all. firstly, plant a tree. this could be easier than it sounds. join or help out a local wildlife group and ask to plant a tree. trees, when fully grown, will help keep the planet cooler. on the same point, you could protest against the demolition of the rainforests. this is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes. something as simple as walking instead of taking the car will help reduce pollution. as well as stopping pollution, you are giving yourself exercise, something important for our bodies. so the next time you get into your car, or your motorbike, think - do i have to make this journey by vehicle or can i walk? when you are at home, and your getting a little cold. put a jumper on and do not adjust the heating.the extra heat produced by our homes also affects the planet. so try wearing an extra layer in winter. if possible, buy your fruit and vegetables from local suppliers. and try to avoid imported goods. the more foreign food that we import the more pollution from aeroplanes and boats it will create. keeping to the speed limit can also help the environment. the more you speed the more petrol you are going to use, making the pollution higher. also, suv?ˉs make about six times their own weight in co2 each year. a small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.

　　if possible use solar energy, after all it is free; all you need to buy is the equipment.

　　you can get much of your hot water and heating from the sun and even generate electricity. reduce, reuse and recycle. only buy what you need; don?ˉt stock the cupboards with things you may or may not use. reuse whatever you can, like containers and paper, and recycle what you cannot reuse. it really is as simple as that. finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money. if everybody stuck to these rules, we would be doing a great thing by protecting the earth. so please take into consideration what i have said, and try to do your part. after all, it will be our next generation that will feel the effects.
