The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.
Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of "sustainable development", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.
What' s more, every citizen should realize the seriousness of the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.
我们生活的世界由于对环境的破坏，正变得越来越难以忍受。禽流感和非典是两个典型的例子，环境破坏可能威胁我们的生活。此外，森林破坏、水和空气污染导致耕地减少和极端天气。
针对这些严重的问题，我们可以提出一些措施来解决它。首先，当局应采取"可持续发展"的政策，关于环境保护的法律应该生效并执行严格，正如我们的政府一直在做的事情。
此外，每个公民都应该意识到问题的严重性，共同努力来保护我们的环境。除此之外，植树有利于改善和美化环境。
