Some natural disaster is hard to resist,but some natural disaster like acid rain,sandstorm and so on is caused by human beings themselves because of their deforestation and overdone pollutant discharge.As a result,water loss and soil erosion,sandstorm and air pollution happen.Therefore,something must be done to protect our environment.We should plant more trees as possible as we can to reduce the loss of water and soil and sandstrom.Besides,we should reduce the use of vehicles.Instead of it,we should take buses or walk to work and school.In addition,we should call on all the people to protect the environment through TV,radio and Internet.
Olny make a clear world can we live long.

Noise Pollution 噪音污染
Noise is among the most pervasive pollutants today. Noise from road traffic, jet planes, jet skis, garbage trucks, construction equipment, manufacturing processes, lawn mowers, leaf blowers, and boom boxes, to name a few, are among the audible litter that are routinely broadcast into the air.
Noise negatively affects human health and well-being. Problems related to noise include hearing loss, stress, high blood pressure, sleep loss, distraction and lost productivity, and a general reduction in the quality of life and opportunities for tranquillity.
We experience noise in a number of ways. On some occasions, we can be both the cause and the victim of noise, such as when we are operating noisy appliances or equipment. There are also instances when we experience noise generated by others just as people experience second-hand smoke. While in both instances, noises are equally damaging, second-hand noise is more troubling because it has negative impacts on us but is put into the environment by others, without our consent.
Noise pollution is not easily defined. Part of the difficulty lies in the fact that in some ways it is different from other forms of pollution. Noise is transient; once the pollution stops, the environment is free of it. This is not the case for chemicals, sewage, and other pollutants introduced into the air, soil, or water.
The definition of noise itself is highly subjective. To some people the roar of an engine is satisfying or thrilling; to others it is an annoyance. Loud music may be enjoyable or a torment, depending on the listener and the circumstances. Broadly speaking, any form of unwelcome sound is noise pollution, whether it is the roar of a jet plane overhead or the sound of a barking dog a block away.
The actual loudness of a sound is only one component of the effect it has on human beings. Other factors that have to be considered are the time and place, the duration, the source of the sound, and whether the listener has any control over it. Most people would not be bothered by the sound of a 21-gun salute on a special occasion. On the other hand, the thump-thump of a neighbour's music at 2 a.m., even if barely audible, could be a major source of stress.
The decibel (dB) (分贝) is a measure of sound intensity; that is, the magnitude of the fluctuations in air pressure caused by sound waves. In fact, an increase of just 3 dB means twice as much sound, and an increase of 10 dB means ten times as much sound.
A sound pressure level of 0 dB represents the threshold of hearing in the most sensitive frequency range of a young, healthy ear, while the thresholds of tickling or painful sensations in the ear occur at about 120 to 130 dB. There is fairly consistent evidence that prolonged exposure to noise levels at or above 80 dB can cause deafness. The amount of deafness depends upon the degree of exposure.
Noise can cause annoyance and frustration as a result of interference, interruption and distraction. Exposure to noise is also associated with a range of possible physical effects including: colds, changes in blood pressure, other cardiovascular changes, increased general medical practice attendance, problems with the digestive system and general fatigue.
We know the sounds of cities are loud enough to cause great harm to people's hearing in the U.
S.One person out of twenty has got some hearing loss.And all over the world the situation is getting worse and worse all the time since the noise increases with the population.
With the development of machines,noise has also increased greatly in the 20th century.We live surrounded by loud planes,trucks and electric tools.TV sets and radios add up to 90 or J00 decibels,a certain unit used to measure the loudness of sound.A normal dialogue reaches 55 decibels; a plane goes to 100,and an ordinary train,reaching the station,can be twice as loud as the loudest plane.Disco music reaches about 118.At decibels the ear stops hearing sound,and pain starts.How terrible if things go on like this!
噪音污染
众所周知,在美国,城市巨大的噪音对人们的听力造成了极大的损害.每20个人中就有一个有不同程度的听力损伤.就世界范围看来,因为噪音随着人口的不断增长,而越来越严重,这种情况也愈发恶化.
20世纪,随着机械制造业的发展,噪音污染也日益加剧.我们生活在震耳欲聋的飞机、卡车和电器中.
电视和收音机加起来甚至达到90至100分贝(分贝：一种测定声音
大小的特定单位).人们普通的对话是55分贝；飞机飞行中为100分贝；而一列普通的火车在到站时音量能够达到最嘈杂的飞机的两倍；迪斯科音乐更是高达118分贝.到达分贝耳朵就会丧失听觉,感到痛苦.这样下去,该是一件多么可怕的事情啊!,7,
ife gets noisier every day and very few people can be free from noise:of some sort or another.It doesn't matter where you live in the middle of a modern city, or a faraway village the chances are that you'll be disturbed by jet airplanes, transistor radios, oil-powered engines, etc. We seem to be getting used to noise, too.
Some people feel quite lonely without background music while they're working. Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums.
The noise level in some discos is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration suggested that although lots of people say that noise disturbs their concentration, what really influences their ability to concerttrate is a change in the level of noise. It goes on to say that a background noise which doesn't change too much (music, for
example) may even help people to concentrate.
