Pollution is the price we pay for an overpopulated, overindustrialized planet. When you come to think about it, there are only four ways you can deal with rubbish: dump it, burn it, turn it into something you can use again, attempt to produce less of it. We keep trying all four methods, but the sheer volume of rubbish we produce vpn软件免费 worldwide vpn软件免费 threatens to vpn免费 overwhelm us. Rubbish, however, vpn免费 is only part of the problem of polluting our planet. The need to produce everincreasing quantities of cheap food leads to a different kind of pollution. Industrialized farming methods produce cheap meat products: beef, pork and chicken. vpn软件免费 The use of pesticides and fertilizers produces cheap grain and vegetables. The 免费vpn price we pay for cheap food may be already too high: Mad Cow Disease (BSE) in cattle, salmonella in vpn免费 chicken and eggs, and listeria in dairy products. And if you think you'll abandon meat and become a vegetarian, you have the choice of very expensive organically-grown vegetables or a steady diet of pesticides every time you think you're eating fresh salads and vegetables, or just having an innocent glass of water! However, there is an even more insidious kind of pollution that particularly affects urban areas and invades our daily lives, and that is noise. Burglar alarms going off at any time of the day or night vpn软件免费 serve only to annoy 免费vpn passers-by and actually assist burglars to burgle. Car alarms constantly scream at us vpn免费下载 in the 免费vpn street and are a source of profound irritation. A recent survey of the effects of noise revealed (surprisingly? ) that dogs barking incessantly in the night rated the highest form of vpn免费下载 noise vpn免费下载 pollution on a scale ranging from 1to 7. The surveyrevealed 免费vpn a large number of sources of noise that we really dislike. Lawn mowers whining on a summer's day, late-night parties vpn免费 in apartment blocks, noisy neighbours, vehicles of all kinds, especially large container trucks thundering through quiet villages, planes and vpn免费下载 helicopters flying overhead, large radios carried round in 免费vpn public places and played at maximum volume. New technology has also made its own contribution to noise. A lot of people object to mobile phones, especially when they are used in public vpn免费下载 places like restaurants vpn免费下载 or on public transport. Loud conversations on mobile phones invade our thoughts or interrupt the pleasure of meeting vpn免费 friends for a quiet chat. The noise pollution survey revealed a rather surprising and possibly amusing oldfashioned source of noise. It turned vpn软件免费 out to be snoring! Men were found to be the vpn软件免费 worst offenders. It was revealed that 20％ of vpn软件免费 men in their mid-thirties snore. This figure rises to a staggering 60％ of men in their sixties. Against these figures, it was found 免费vpn that only 5％ of women snore regularly, while the rest are constantly woken or kept awake by their trumpeting partners. Whatever the source of noise, one thing is certain: silence, it seems, has become a golden memory.
The topic of this text, enviromental pollution, has already become a very serious problem nowadays, not only in China but all over the world. We have heard about different kinds of pollution, e.g. vpn免费 air pollution,water pollution,soil pollution,or pollution resulted from traffic, or factory, manufactory, different kinds. And we have heard about such term as vpn免费 smog which is smoke and fog, or vpn免费下载 the greenhouse effect(温室效应).The reason is we have a vpn免费下载 growing population but the vpn免费 natural resources are not inexhaustible and not renewable.自然资源并不是取之不尽用之不竭的。
What should we do in face of such a problem? Some ppl suggest that we should use alternative natural resources or altenative energies, such as energies generated from the sun, or the heat of the earth, or from the sea. Is there anything that vpn软件免费 we can do as individuals? In the western countries, some ppl suggest that we should stop driving our own cars,instead we should use public 免费vpn transport. And at least there is one thing we can do,which is,to recycle garbage.一件小事我们都可以做，就是把垃圾分类，这样可以再利用有些资源。 Alright,so much on the topic of enviromental pollution(环境污染)and enviromental protection(环保). I'll see 免费vpn u next time.
Smog, which is a combination of smoke and fog, is generated from industry emissions, motor vehicle combustion, incinerators, open burning, and other sources.
