版主把这个版块整得很热闹啊,我也来凑个热闹。
最近看到一篇文章:
    There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”— conserving heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
    Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature — a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would mane agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible) Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?

这个文章说了两个方面:
1、随着工业发展,废气的排放,产生温室效应,使地球气温升高,冰山融化,淹没城市
2、由于环境污染严重,大气中的废弃物和粉尘,会反射太阳阳光,造成地球气温下降,进入冰河期

看到这篇文章我对温室效应和大气污染有了新的认识

我用翻译软件稍微翻译了一下,大家凑活看哈。
还有人认为空气污染只影响周围的重型汽车工厂和大城市地区的交通立即。目前,我们认识到,虽然这些是最严重的空气污染的地区,问题是全球字面上。在过去十年多次,
空气污染的浓密云层已覆盖了美国东部和远离带来任何制造和汽车交通的主要集中在农村地区的健康警告。事实上,整个地球的气候很可能被感染的空气污染。一些科学家认为,二氧化碳浓度的增加dioxid
在从燃烧化石燃料(煤和石油)产生的空气e是创造一个“温室效应” - 热反射保护地球和提高全球的平均温度。如果这种说法是正确的,世界上温度升高只有少数学位,极地冰盖的融化会很多,如纽约,波士顿,迈阿密城市,新奥尔良将在水。
另一种意见认为,不普遍认为,是增加大气中的具体问题是阻挡阳光,降低地球的温度 - 这一结果将同样灾难性的。一个只有数度下降,可能会造成了接近一个新的冰河时代,并将鬃毛农业很难或不可能在我们最重要的农业地区的许多。
今天,我们并不确切知道,这些条件都将发生(尽管最近的政府工作报告在起草该领域的专家得出结论认为,温室效应是非常可能的)也许,如果我们足够幸运,这两个趋势将相互抵消和世界的温度将保持大致相同,因为它是现在。经济利润的驱动下,人们忽略的是“先进文明的环境所造成的损害”。也许是空气污染的代价人类要为它们的发展。但是,这是否值得?

这两个极端都是致命的

那么互相抵消有多少可能性?

我觉得一直在相互抵消!现在地球还是相对平稳的。

这真是两个极端,如果我们“想入非非”,期待两者抵消,地球保持平衡,那将是自欺欺人。人类的活动如果不与自然和谐,必将受到自然的惩罚,美丽的地球需要人类认真呵护。
