Why don't we choose Low Carbon life？
我们为什么不选择低碳生活呢？
My speech is “Why don't we choose Low Carbon Life?" 2010 World Expo was held in Shanghai. Shanghai Expo’s theme is "Better City, Better Life." As a student, we should do something about environmental protection. For example, plant trees, save water and less your car. Tree can make the air has become cleaner. We can make use of the water cycle; we mustn’t to always use clean water. We should tell our parents, less one day driving, it is very important to reduce the city's carbon dioxide. We can take the bus, subway, bicycle or on foot, which is also conducive to your health.
我的演讲标题是：我们为什么不选择低碳生活呢？2010世博会在上海召开，其主题是---城市，让生活更美好。作为一名学生，我们应为环保做贡献。例如多植树、节约用水、少开车等。树木可以让空气变得更清新干净，我们应尽量循环用水，生活中不要总用净水。我们应告知父母少开车，这对减少城市的二氧化碳含量非常重要。我们可以选用对健康有利的出行方式，如坐公交、地铁，骑自行车或步行。
I hope we can do it.
希望人人都能做到。
Then, how can we live a low-carbon life? Firstly, we should recognize that low-carbon life is not only a kind of lifestyle but also life attitude. Each of us is responsible for the greenhouse gases we emit in our daily actions. Secondly, we should develop good habits in our daily lives. We can select products with longer shelf life when we shop. Paper cups are made from cutting forests. We should try not to use them, or select the smaller ones when we do because trees can absorb carbon dioxide and reduce greenhouse gas. We should use efficient light bulbs which use about one-third of the energy of normal bulbs and last 10 times as long. And the lights should be turned off when not needed. We print things out only when necessary, and print double-sided and reduce the margins. All motorized travel is carbon-intensive. Buses and trains are better than cars, but walking or cycling is better still. It's also better for our health and cheaper. There are so many low-carbon life actions that it is impossible to list all of them. Low-carbon life can be summarized as moderate food, house, transportation, more sports and not wasting.
那么我们该如何低碳生活呢？首先，我们该意识到低碳不仅仅是生活方式，它还是种生活态度。每人都该为自己生活中带来的温室气体负责任。其次，日常生活中要培养良好的生活习惯。选购保质期长些的产品，纸杯源于树木的砍伐，我们应尽量不用纸杯或用小一些的，因为树木能吸收二氧化碳并减少温室气体的排放。我们应使用节能灯，因为它们的能耗只是普通灯泡的1/3，寿命却长10倍。不用电时将电灯熄灭，只在有需要时进行打印，要双面打印并缩小行距。所有的机动车都是碳密集型的，公交和火车优于机动车，但步行或骑自行车更好，它们不但有利健康且花费更少。低碳的生活方式种类繁多，在此就不一一尽列了。低碳生活可概括为合理膳食、良好的居住环境、环保的出行方式、多做运动及节约能源。
Many hands make light work. If we all do like this, the effect will be evidence. I hope all of us can do it.
正所谓“人多力量大”，如果人人都能身体力行，那效果可见一斑。我希望大家都能行动起来！
That’s all, thank you.
这就是我的演讲内容，谢谢！
