怎样保护地球英语作文优秀【二】

地球使我们全世界的“母亲”我们要保护她，关爱她！

现在随着时间的推移，人口的快速增长，各种不良现象出现十分平凡。如：乱砍乱伐，滥用化学药品……我们为了保护地球，我们应该多关注自己身边的事，都做一些对环境有益的事。

人口的快速增长，是地球表面可耕种面积越来越少，严重缺乏淡水。而现在的人口增长迅速，如果按照这样的情况下去，地球总有一天会应承受不住而累垮的！在说了人口的快速增长，使全球的气温急剧上升，所以我们要控制人口的增长，实行计划生育。

而人类的大量砍伐，使得一些地方植被极少，很容易发生洪灾、沙尘暴、泥石流、山体滑坡等一些重大危害，那人们的伤亡肯定会很严重，所以我们还应该多植树造林，减少一些可以避免的危害，如：泥石流、山体滑坡等一些危害，树木的减少，会使二氧化碳增多，氧气减少，使我们不能呼吸新鲜的空气。此外，我们还应该大力宣传有关保护地球的知识，使人们对这一方面更加重视。

然而，化学用品的滥用，不仅污染了空气，对人们的生活起居也带来了不便。如果，河水被污染，会使很多的鱼儿失去珍贵的生命；如果农田里的.庄稼被污染，那会使那年的产量大大减产；如果大量使用农药，使严重缺乏淡水的地球会更加不堪重负。

“保护地球人人有责”，我们应大力宣传，减少不应该发生的灾害，使我们的“地球母亲”永远长寿！

Tiger is one of the most valueable animals to human beings today. It is somehow like a cat, but much bigger than it. It lives in the forest, and feeds on small animals.

Nowadays, the number of the wild tiger is becoming small and small. Maybe there will be no tiger any more if people continue cutting the trees, destorying the living environment or hunt the tiger just for the skin. We must stop all these mistakes. We should protect them, because the world without tiger is not a completed one.

the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?

the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.

even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.
