敬爱的老师，亲爱的同学们，大家好！
在亿万年孕育后，地球本应该变得更加美丽，但是当人们再次从外部看它时，地球，却出现了几朵不和谐的阴云。
我生活在北京——这个我一直引以为豪的现代化都市，也是一座充满着历史文化气息的古城。可是，现在我越来越多地感受着环境的恶化：灰色经常充满了每一寸的空气，那死寂的颜色无时无刻不警告着人们它的危害。这样的环境让我无法在户外自由的呼吸和行走，使我不得不时时为健康担忧。我知道，在历史上，英国伦敦也曾是国际上“赫赫有名”的雾都，美国洛杉矶也曾遭遇过严重的污染事件，经过不懈地努力，那里的环境最终得以改善，蓝天白云和青山绿水又重新回到了城市。
北京，也许只是中国的城市缩影。如今，雾霾遍布了几乎整个中国；河流和地下水源受到污染，曾经有一次在兰州，被污染的水源导致水价暴涨，瓶装水涨到一百多元一箱；树木，被滥砍滥伐，矿产，被野蛮开采，使全中国的森林覆盖率不到20%，由此不仅带来了严重的水土流失问题，也让气候条件更坏；更加严重的是工业高速的发展，大量的废水、废气和工业垃圾被无节制排入我们周围，让环境不断恶化。面对这样严峻的形势，我们绝不能无动于衷。
而中国，又仅仅是世界的缩影。长期以来，人类把文明的进程一直滞留在对自然的征服掠夺上，似乎从未想到对哺育人类的地球给予保护和回报，在取得辉煌的文明成果的同时，人类对自然的掠夺却使得我们所生存的自然环境却遭受到愈来愈严重的破坏：气候变暖，臭氧层空洞，酸雨，有毒废弃物，野生生物灭绝，以及大气、水污染等，这是我们当前面临的一连串全球环境问题，面对这些问题，我们该做些什么呢?
地球无私地给予着我们资源，她的环境无比美丽。我们能在这里享受着花朵甜美的香气，在这里感受雨林生物的多彩。街边的绿树红花彰显出北京的美丽，海洋中连绵的珊瑚礁又透出大海的神奇。这是地球给我们的馈赠，我们应当倾尽努力去保护她。
地球只有一个，她是人类赖以生存的美丽家园。善待地球，保护地球，保护资源环境，就是保护我们自己，同时也为我们子孙后代留下美好的家园。虽然我们现在还只是学生，不可能为全人类的环境做出特别大的贡献，但我们可以从身边的环境做起，从小事做起，例如：学习环保节能观念，多走路，绿色出行，建议父母少开车，低碳生活。避免使用一次性饮料杯、泡沫饭盒、塑料袋和一次性筷子，减少垃圾的产生，防止污染环境。另外，政府应该抓紧对垃圾进行分类回收的管理，特别是回收废旧电池。让我们积极参与环保宣传，做一名合格的环保志愿者。
我们生活在同一片土地上，我们拥有着共同家园，关心地球就是关心我们自己的家，保护资源就是保护我们生存发展的基础。地球，赋予人类独一无二的智慧，让人类成为万物之灵，是为了管理地球，保护地球，建立美好的奇迹，它无私的给予我们资源，而我们呢？我们无比幸运的被选中，却要无比愚昧地一错再错吗？滴水成川，积土成山，保护环境，让我们都行动起来。
我的演讲到此结束，谢谢老师同学的聆听!
Hello, my wonderful teachers and classmate
In the empty and quiet universe, there is a blue planet, its colors are like a pure and clear sapphire. But it's just like the sapphire that was carefully made and scraped of all of its imperfections with thousands of trials by the most skilled craftsmen in the entire universe. This sapphireis what we call: Earth.
After centuries past, Earth was supposed to become amore beautiful place, but when people look at the earth from space. Earth instead is starting to have unusual gray clouds that add imperfection to the perfect Earth centuries ago.
I live in Beijing-the city I thought was a modern and rich city, with the modern thing, this city also has old city preserved throughout the centuries. But, now I am starting to see the environmental damage that we have done: Gray usually is filled in every inch of air. The dark color at all moments warns the people of its deadliness, this environment makes me no longer safely and freely breath and walk. I know, in the past, London England was also the famous“Smog town”, Los Angeles America also had damaging environmentalproblems. But after had work, in the end, the environment was back to how itwas, with green trees and beautiful rivers again.
Beijing, maybe only in China’s largest cities. Now smog covered the entire country of China; streams and under ground water are getting polluted. Once in Lanzhou the polluted water source caused water costhighly increasing, with bottled water about 100 yuans per box. Trees are being cut down, various minerals are being all mined up. This made the entire China’s forest percentage under 20%. With this came the mud slides and air damage. The most important with the highly development of morden industry, liquid wastes,solid wastes, and air wastes are spreading next to us unstopped, making the environment more damaged. Facing the hard challenge, we can’t give up.
But China is just a small portion of Earth. For a long time, Humans made civilization on top of the environment. Almost no one ever thought to give Earth some help or something in return for protecting the Humans. While making our civilization more advanced, We are damaging the Earth in return:Global warming, acid rain, poison leaks, wild animals going extinct. These are what we are facing for the whole Earth. Facing these problems, what can we do?
The Earth giving us all it can provide for us, and with her beautiful environment. We can live here smelling the flowerssweetness, seeing tropical plants, and animal’s differences. Street sides greentrees and red flowers shows Beijing’s beauty, the sea tide with coral reefshowing its secrets. This is what the Earth have offered, we should protect it at a cost.
Earth is only one being, but she is Human’s beautiful home. Help the Earth, protect the Earth, protect the ecosystem, is protecting ourselves. At the same time leave a better place for our sons and grandsons.Even though I am still a student, it’s impossible to help the Humankind too much. But we can still start from doing little things around us. For example,walk more, suggest parents drive less and use buses, useless one-timeaccessories, and help protect the planet. Also, the government should focus on the waste recycling, especially old batteries. Letting us help to protect the environment, being a good volunteer.
We live on the same planet, having the same home, caring about the Earth is caring about our homes. Saving resources is saving our living basics. Earth, providing Human knowledge, is to let human help govern the Earth, protect the Earth, make Eartha better place. She gives us as much resource as she can provide. But for us?We are lucky to be chosen but foolishly make more and more mistakes. Water drops make a lake, piles of dirt makes mountains. Protect the environment, let us all start. My speech ends here, thanks for listening.
