Hundreds of desert in the world,although the water on the earth for 70% of the earth,however,there are many sewage on earth?Scientists statistics,the water in the world have 40% by human pollution,cannot use the more can not cycle.Hundreds of millions of people in the world,if each day,then the global will waste a drop of water is wasted; hundreds of millions The rather than a drop of water.In the world,you can know how many people drink less than a glass of water,day,how many students like us so big,because of water shortage,is in Wisconsin next!世界上有几百处沙漠,虽然地球上的水占地球的70%,可是,有多少的污水在地球上呢?科学家统计,世界上的水有40%被人类污染,不可使用更可不可循环.世界上有上亿人,如果每人一天浪费一滴,那么全球就有上亿滴水被浪费；更何况不止一滴水啊……,你们可知道世界上有多少的人,一天喝不到一杯水,有多少人像我们这么大的学生,因为缺水,正威在旦夕!
The future of the world flourishing,indeed,however,Now,if people start without restraint,abuse of ecological resources
then,If in a two hundred years later,the world will have so beautiful brilliant?If at that time,...Humans have a flying car,so,the clouds of heaven is not white,but dark grey,make the person touched direction,the sky is blue also no longer ausgestorben black; If,then,when a 200 years,have go diving train,then,is not the vast sea,not blue,but a dry yellow scene,no sea creatures,not even the freedom of fish; If,again lead 200 years...
The human will still live in a beautiful world?And they will travel to countries admire the view?Never.
So,because we have such a beautiful earth,we should like to cherish the most precious similar cherish it!Don't let the tears become the world last drop!
繁荣景象,的确美不可言,但是,如果现在的人们就开始不加节制地滥用生态资源,那么,如果在过上200年,世界还会有那么美丽辉煌吗?如果,那时侯……人类有了会飞的汽车,那么,天上的云并不白,而是暗灰色,使人摸不着方向,天空也不再湛蓝是一片死寂的黑色；如果,再过上200年,那时候,有了会潜水的火车,那么,海并不辽阔,并不蔚蓝,而是一片干黄的景象,没有海底生物,更没有自由自在的鱼儿；如果,再过上200年……
那时候的人类依然会活在美丽的世界里吗?他们还会到各国观赏风景吗?绝不会了……
所以,因为我们有个这么美丽的地球,我们应该像珍惜最宝贵的东西一样珍惜它!不要让眼泪成为世界上最后一滴水!
