常春藤生活英语【23】生态足迹（在线收听）

How often do you eat meat? Do you recycle? Do you drive a car? Depending upon your answers, you may have a big or small ecological footprint. An ecological what? Of course we all have footprints. We leave them in the mud or after stepping in a puddle, but the ecological footprints that we leave on the Earth are far more important.

By looking at one's ecological footprints, we can see how much a person impacts our planet Earth. The things one does, the products one uses, and how one consumes natural resources are part of that person's ecological footprint. Let's say you eat meat and a lot of processed food every day. You also ride a scooter to work and never recycle. These things amount to having a big ecological footprint. On the contrary, a vegetarian who rides a bike everywhere and recycles everything would have a much smaller ecological footprint. In other words, this person's life doesn't hurt the environment as much as your own. Now, what do you do if you have a big footprint?
　　
您多常吃肉？您会做资源回收吗？您是否开车？根据您的答案，您的生态足迹可能或大或小。生态什么？我们当然都有脚印。我们在泥泞中、或是踏过水坑后，都会留下印子，但我们在地球上所留下的生态足迹可是重要得多。

藉由观察一个人的生态足迹，我们可以检视人们对地球造成的冲击有多大。一个人所做的事，所使用的产品，以及如何消耗天然资源，都算是那个人生态足迹的一部份。假设您每天都吃肉类及许多加工食品。您还骑摩托车去上班，而且从不做资源回收。这些将累积为一个巨大的生态足迹。相反地，一个什么东西都会回收、以及到任何地方都骑脚踏车的素食主义者，所留下的生态足迹会小很多。换言之，这个人一生对环境造成的伤害会比您本身还少。假如您的脚印很大，那您现在该怎么做？
