With the intensification of human activities, the ozone layer of the earth's surface appears serious hole. Maybe ozone layer is abstract to many people. Let me take a metaphor, ozone layer just like the clothes of our human beings. If our clothes are damage, we will get hurt at last. Recently, as the developing of science and technology, there are more and more new products coming into the world. They bring great convenience to human beings, but they also join the group of damaging ozone sphere at the same time. For example, Freon coming from refrigerator does harm to the ozone sphere. If the ozone layer is destroyed, our mankind will have to face great damage. We will have more chance to get skin cancer, cataract and so on. And there are other living things will be affected. The marine ecosystem also couldn’t avoid this disaster.

随着人类活动的加剧，地球表面的臭氧层出现了严重的空洞。对于很多人来说臭氧层也许是很抽象的。让我来打个比方吧，臭氧层就像人类的衣服。如果我们的衣服坏了，最后我们肯定会受伤。近年来，随着科学技术的发展，出现了越来越多的新产品。它们给人类带来了极大的便利，但是他们同时也破坏了臭氧层。例如，来自冰箱的氟利昂就会伤害臭氧层。如果臭氧层被破坏，我们人类将面临巨大伤害。我们患皮肤癌，白内障等疾病的几率会上升。还有其他的生物都将受到影响。海洋生态系统也无法避免这场灾难。

Therefore, we need to do something to protect the ozone sphere to protect ourselves. We should not use air conditioning, refrigerator, cars, spray and the product containing CFCs. But I think the first thing we need to do is improving our environmental protecting conscious. How many people know that 16th, September of every year is the International Ozone Layer Protection Day? In order to make a healthy living environment and the future of human being, please try your best to do something.

因此，我们应该要做一些事情来保护臭氧层，保护我们人类自己。我们不应该过多地使用冷气，冰箱，汽车，喷雾剂以及含氯氟烃碳化物的产品。但我认为我们首先需要做的事情是提高我们的环保意识。有多少人知道，每年的九月十六日是国际臭氧层保护日？为了人类的未来并营造一个健康的生活环境，请尽量做点事情吧。
