In recent years, tourism has developed rapidly in China. Many people believe that tourism produce positive effects on economic growth and we should try our best to promote tourism. But what these people fail to see is that tourism may bring about a disastrous impact on our environment. As for me, I'm firmly convinced that too much tourists bring harm to the environment.
The bad impact of tourism on the environment has mainly expressed itself in various ways. One way is the proceof exploiting a new scenic spot. In order to attract tourists, a lot of artificial facilities have been built, which have certain unfavorable effects on the environment. This proceusually breaks the ecological balance of the area. In some mountainous places, trees are being cut down to build hotels for others to see and explore the beauty of the mountains. Then land slides and mud-rock flows come up. Another way the development of tourism has damaged the environment occurs when tourists go to scenic spots. Some tourists don't have the awareneto protect the environment, and ignorantly throw their garbage here and there. Some people even kill the local wildlife to eat, which badly damages the balance of the natural environment.
It is wrong to sacrifice the environment for the growth of tourism. We must keep in mind that too much tourists bring harm to the environment. We need to find a balance between satisfying the needs of tourists and reducing to a minimum the pollution they cause.

Will Tourism Bring Harm to the Environment? Tourism has developed by leaps and bounds in the past decades in the whole world. Therefore, the issue of whether the tourism will bring harm to the environment is becoming a matter of concern. As for me, I hold that the tourism does more harm than good to the world. In the first place, the more places we travel to , the more pressure will be added to the environment. Take Dunhuang as an example, the greatest scourge these days comes from the tourists who swarm here by the busload , bring destructive amounts of carbon dioxide and moisture into the caves along with their eagernefor a glimpse of ages past . Secondly, It has become fashionable for travelers to drive a private car to the place they want to . In this case ,a large number of cars are mushroomed in the road and it cause twice as much as air pollution .At this speed ,we may live in a world which is full of dirty air instead of fresh air. In sum , although tourism is playing an indispensable we`d better try to limit role in the society , I still believe that its speed according to the harm that brings to the environment.
The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.
Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of "sustainable development", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.
What' s more, every citizen should realize the seriousneof the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.

as we know , water is very important to man, we can’t live without water. the amount of water which is suitable to drink is less and less. but some people don’t care about it .they waste a lot of water in their daily life. even worse, they pour dirty water in to rivers. they throw rubbish into rivers , too. many rivers and lakes are seriously polluted.something must be done to stop the pollution. only in this way can we live happily. if we don’t save water, the last drop of water will be a tear-drop of us.
we know that despite the fact that seventy percent of the earth＇s surface is covered with water, only a little part of it is fresh water. yet the demand for fresh water in our daily life and in industry seems great. moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. it is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. what is worse, more and more water resources are being polluted, making the water unfit to use.
in addition,we must warn the people of the importance of water and the danger we are facing.for example, in most asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet. furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.
