Water is very useful, we drink water every day, wash with water. In many places there is not much water, we should not waste water, we should use water and save water.
Not only to save water and other energy saving. Most of the energy we use comes from coal and oil. There is not much coal and oil on the earth. We should save energy. We shouldn't drive too much, because cars are going to use a lot of energy.
The development of science and technology, make the earth's green less and less, so we can not cut down too many trees. Because wood comes from trees, and we use wood to make tables, chairs and many other things. And trees can also purify the air, beautify the environment.
The white pollution on the earth is becoming more and more serious. We use plastic to make bags and bottles, but too much plastic is harmful to the earth. We should not use too many plastic bags and plastic bottles. We should use paper bags and glass bottles.
Well, say so much, the future of the earth or rely on our actions!
水很有用，我们每天喝水，用水洗东西。在许多地方没有很多水，我们不应该浪费水，我们应该再利用水并节约用水。
不仅水要节约其他能源也要节约。我们所用的绝大部分能源来自煤炭和石油。地球上没有很多煤炭和石油。我们应该节约能源。我们不应该开车太多，因为汽车要使用许多能源。
科技的发达，使得地球上的绿色越来越少，所以我们不能砍伐太多的树。因为木材来自于树木，我们用木材来制作桌子，椅子和其他许多东西。并且树木还可以净化空气，美化环境。
地球上的白色污染也越来越严重。我们使用塑料来制作袋子和瓶子，但太多的塑料对地球有害。我们不应该使用太多的塑料袋和塑料瓶。我们应该使用纸袋和玻璃瓶。
好了，说了这么多，地球的未来还是要靠我们行动的！
