但我们为经济的飞速发展付出了高昂的代价：资源的过度开发，环境的污染。直接影响人们的生活质量，甚至威胁到人们的健康。

政府虽然认识到问题的存在，但是没有有效的应对手段，人们的环保意识薄弱，整个环保体系不完善。

我们已经造成了无法挽回的损失，现在如果不开始采取有效的手段去控制，作为世界上人口最为众多的国家，我们的后代将面对灭顶之灾。

在这历史的关键时刻需要有人去承担责任，对未来负责，作为21世纪中国新生代的一员，我愿意贡献我的才智和精力去承担这一使命。

We have already caused irreparable damage, if we do not begin now to take effective means to control, as the world's population of the most numerous countries, our future generations will face extinction.
