I think if we protect the natural environment and prevent its deterioration,there wouldn’t be too many natural disasters.For example,if we don’t cut trees too much, there won’t be too many floods and sandstorms.It losses to us will also be reduced.Moreover, people die every year as a result of floods.So it is important for us to protect the environment.2
Nowadays, survival environment has been destroyed by human’s overuse and wasting the natural resources. The wasting of resources is not good for our subsist. The resources nowadays are decreasing day by day, but the waste that we produced is increasing day by day. There’s a variety kind of trash in the ocean, Such as plastic bag and fruit core， which cause a great damage to the environment. Second is because the destruction of environment, we need to plant tree to make sure human being can be existed on this plant Earth.3
If we don’t conserve, the earth resources will slowly dwindle and finally vanish, Biological species on earth are valuable non-renewable natural resources.
I think, we, human, are a part of great wisdom. But we will never understand a higher order, which is called “nature”. It doesn’t punish, It doesn’t reward, It doesn’t judge, It just exists. But if we try to control or damage it, Something follow this order will kick our ass, like famine, drought, and green house effect. Let us do some conservation! For a brighter future; for our offspring can still know that how beautiful our planet is; for humans can still living on this blue gorgeous planet!5
At the first of all, let me talk about the recourses of water. As you know, in our earth the proportion of the area--- 79% of water, and only 21% of land. Many people may say that we still have so much water. But the truth is that we don’t use much water. In our life, there are many behaviors that waste water. Those action both are very normal. Such as: brush your teeth and wash your face without touching the faucet, there is a lot of water wasted here. Although, someone think there is no shortage of water in your hometown or this city Shanghai. Have you ever thought about how many places in the world are short of water? In some places they can even see water as money, because water is very precious. I think it is very necessary and crucial to protect water resources. If we don’t have water, I don’t know what our life will look like in the future.6
Conservation. It’s a necessity. It’s a daily necessity. But it’s a special kind of necessity, because it’s a necessity that depends on us, human beings. I believe that it is a topic that is familiar to each and everyone of you. Basically, thrift is a concept where you reduce, reuse and recycle.
