A：现在中国很多城市都有严重的雾霾问题。从以前的水污染、土地污染、海洋污染到现在的空气污染，我们似乎从来没有逃脱过环境问题的困扰。我真的不知道人们到底有没有意识到这些问题的严重性。
B: Due to the pressures of overconsumption, population growth and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960s, environmental movements have created more awareness of the various environmental problems.
A：既然我们越来越意识到了环境问题，那我们有没有采取什么措施呢?这些措施到底有没有发挥作用?
B: Take the U. S. for example, Beginning in the 1960s, Americans have become increasingly concerned about the environmental impact of industrial growth. Engine exhaust from growing numbers of automobiles, for instance, was blamed for smog and other forms of air pollution in large cities. Pollution represented what economists call an externality—a cost that the responsible entity can escape but that society as a whole must bear. With market forces unable to address such problems, many environmentalists suggested that the government have a moral obligation to protect the earth’s fragile ecosystems, even if doing so required some economic growth to be sacrificed. In response, a slew of laws were enacted to control pollution, including the 1963 Clean Air Act. the 1972 Clean Water Act, and the 1974 Safe Drinking Water Act. Of course, I believe all countries have taken their measures to counter environmental pollution.
A：那么作为我们个人，在环保事业中又可以发挥什么作用呢?
B: I can give you some tips here: Stop smoking. If you don’t smoke, you lessen air pollution and improve your lung health. Conserve water. Wash your clothes and dishes only after you have a full load. Unplug things. If an item isn’t in use, that doesn’t mean it isn’t requiring electricity while plugged in. If you can, avoid using plastic water bottles and paper.
A：谢谢你给我提的这几个点子，我一定会照做的。
B: You are welcome.
