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 make 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?

A煤矿是有2000余人的年产120万吨原煤的中型煤矿。2006年上级主管部门特拨下15万元奖金，奖励该矿在安全与生产中做出贡献的广大员工。在这15万元奖金的分配过程中，该矿矿长召集下属五位副矿长和工资科长、财务科长、人事科长和相关科室的领导开了一个“分配安全奖金”的会议，这些高层管理者认为，工人只需保证自身安全，而主管们不但要保证自身安全还要负责一个班组、区、队或一个矿的安全工作；尤其是矿领导，不但要负经济责任，还要负法律责任。因此，会议决定，将奖金根据责任的大小分为五个档次，矿长3000元，副矿长2500元，科长800元，一般管理人员500元，工人一律50元。奖金刚好发完，奖金下发后全矿显得风平浪静。但几天后矿里的安全事故就接连发生。当矿长亲自带领工作组到各工队追查事故起因时。矿工们说：“我们拿的安全奖少，没那份安全责任，干部拿的奖金多，让他们干吧!”还有一些工人说：“老子受伤，就是为了不让当官的拿安全奖。”
