During the last twenty years there has been increasing concern with the quality of the environment. Along with air and water pollutants, noise pollution has been recognized as a serious pollutant. As noise levels have risen, the effects of noise have become more obvious.
Noise is described as unwanted sound. Causes of noise pollution include traffic, aircraft, rock bands, barking dogs, television, garbage trucks, and noise from neighbors, voices, alarms and boats. Studies show that over forty percent of Americans are disturbed at home or lose sleep because of noise pollution.
Noise has bad effects on people. Noise interferes (干扰) with human activities at home and work, and is in various ways dangerous to people’s health and well-being.
When we think, talk, listen to music, or sleep, we need quiet. Even low levels of noise can be annoying or frustrating. Sudden increases in volume can make sounds annoying. The quieter the background is, the more unpleasant a noise can be.
Noise can also make instructions or warning unclear, resulting in accidents.
Long exposure to noise levels above eighty-five decibels (分贝) can damage inner ear cells and lead to hearing loss. Noise can result in the uncontrolled fear response and can cause adrenaline (肾上腺素) to be pumped into the bloodstream, the heart rate to quicken, muscles to tense, breathing to increase, and the digestive system to slow down.
Local government has the responsibility to fight noise pollution. For example, it can regulate the speed of trains through their community. On the other hand, ad responsible citizen will never make noise pollution wherever he is.

Last term I joined in a geography research group. Our topic was environmental pollution and protection. We took many pictures to show the present pollution problems of our city. To our surprise, there are still a lot people doing silly things to our surrounding. Some people threw rubbish anywhere, but some cars give off harmful gases. What surprises us mostly is that waste water is sending into rivers by some factories. Worse still, people sometimes have to make their way through smog as the result of the pollution. Through our research, we have come to realize that everybody must pay attention for our environment and taking some measures to protect it.
3 . Slat's life began to change after a holiday trip to Greece with his family when he was 16. What he actually saw in the ocean was an awful lot or plastic waste. From that moment on, Slat dived into a project to find a solution to this alarming problem. Struck by the idea of a floating barrier that could collect plastic, he founded his company, The Ocean Cleanup, at the age of 18. Although the idea was named one of the best inventions of 2015 by TIME magazine, he received negative feedback from the specialists in environmental issues.
Slat was not discouraged and saw his mission as a race against time. It is estimated that up to 14 million tons of plastic enter the oceans from land every year. Plastic gradually breaks down into very small pieces called microplastics, which can eventually enter the food chain.
After five and a half years' hard work, the Dutch inventor launched the world's first ocean plastic cleanup system: System 001. The U-shaped pipe, about 609 meters in length, snakes its way out under the Golden Gate Bridge into the Pacific. These floating barriers will capture plastic waste as the ocean currents flow past. Ships will collect the waste and bring it to land for recycling every few months. According to Slat, if all goes to plan, an array of 60 systems could reduce the amount of plastic there by as much as 50 percent by 2025.
However, there remains a problem: What will happen to the plastic brought back to shore from Slat's systems? It's likely that lots of the waste will eventually be recycled into more single-use plastics that end up back in the oceans. That doesn't mean Slat will give up.

4 . The loud continuous noise of the cars or the sound of a plane can force its way into the deepest forest, yet it’s not only humans that are bothered by the noise.
Bioacoustician Bernie Krause has been studying the effect of noise pollution on wildlife, and has come across some interesting behaviors, especially among animals that communicate by vocalization（发声）, like humans. Birds use sound to communicate, but in noisy places, these animals have to shout over the natural noise to be heard.
Krause mentions a study of nightingales to clarify what he means. The birds responded to traffic noise by singing louder and louder until they actually went beyond noise pollution standards in the city. To belt out (sing loudly) their songs, they increased their lung pressure fivefold, but scientists state that this is not dangerous for the birds themselves.
Studies show that sudden noise can cause certain birds to leave their nests, exposing the young to their enemies. One study also showed that songbirds that nested close to busy motorways were much less productive than those that nested farther away. Mammals（哺乳动物）too are affected. A recent study showed that nursing caribou responded to plane noise by not producing enough milk to feed their young.
In some cases noise pollution can actually help some animals while harming others. Toads（蟾蜍）and frogs are known to vocalize in synchrony（同步；同步方式）so that no predator (their enemies) can zero in on them. Krause found that when planes flew overhead and disturbed the toad’s song, they lost their synchronicity, and it took them 45 minutes to get it back again. That gave their natural enemies plenty of time to find and catch individual toads by sound.
According to Kruse, “Not only will noise pollution bother wildlife, but it won’t help our lives either.”

When I was a child, I hoped to live in the city. I think I would be happy there. Now I am living in a city , but I miss my home in countryside. There the air is clean or the mountains are green. Unfortunately, on the development of industrialization, the environment has been polluted. Lots of studies have been shown that global warming has already become a very seriously problem. The airs we breathe in is getting dirtier and dirtier. Much rare animals are dying out . We must found ways to protect your environment. If we fail to do so , we‘ll live to regret it .
