保护我们的牙齿的作文英语【二】
衣服破了可以补，桌子坏了可以修，鞋子脏了可以洗，人有病了可以医治，可是地球妈妈要是病了，就无药可救了。所以我们一定要像爱护生命一样，爱护我们的地球妈妈。
地球妈妈已经45亿岁了，早在50万年前便生下了人类，妈妈一直用她那甘甜的乳汁抚养着我们，直到现在。妈妈的身上有青山，有绿树，有海洋，还有草坪和森林。真是又美丽又伟大的母亲啊！
大家都知道，地球上只有植物才能吸收二氧化碳，呼出氧气。
科学家曾经计算过3棵树一天吸收的二氧化碳相当于1个成年人呼出的二氧化碳。照这样计算，植物对于人类实在是太重要了。所以，我们一定要好好保护植物。
假如我是一棵小树，我要像那些只知道盖房子、建工厂、作家具的`人们和那些乱砍乱伐的人们提出忠告：请不要乱砍乱伐我们的树木了，也不要再乱踩踏我们的小草兄弟了。否则，我们的家族就会被砍光、伐光、踩死的。到那时，这个地球将会成为二氧化碳的世界，直接威胁到地球妈妈和她千千万万个子孙后代的生存！因此，我们必须下大力气去制止这些公害和私害的发生。而且，我们还要大量植树，净化空气，绿化我们的地球母亲！
假如我是一条小鱼，我的愿望是：请那些造纸厂、化工厂等工厂的叔叔、阿姨们不要再把那些废水废物派泄到我们鱼类生活的地方——大海、河流、小溪……否则，蔚蓝的海洋、清澈的河流及小溪将会变成一片污水。到那时，不但我们兄弟姐妹会被这又脏又臭的污水毒死、灭绝。更严重的是，如果工厂里的废水废物流进了人类的饮用水里，那么，人类和其他动物喝了这些水，便也会死去。
由于现代工业的快速发展和人们生活水平的不断提高，工厂越来越多，汽车遍地都是，大量造成了废气的排出，严重的污染了空气，导致大量树木的死亡，并直接危害到人类的健康。
假如我是一名科学家，我一定要发明一种废气利用的方法，使这些废气不但不会污染空气，而且还能造福于人。
最后，我还要代表地球妈妈告诫那些人口过剩的国家，现在地球上已经有60多亿人了，应该严格控制人口的增长，搞好计划生育。否则，地球妈妈的乳汁被吸干了，还有谁来养育我们呀！没有了母亲，哪儿来的子孙后代！白垩末期时，恐龙因为大吃大喝而吃光了地球上的食物，吸干了地球妈妈的乳汁，而导致死亡的悲惨一幕不要在我们人类身上重演！保护地球是地球上每一个人的责任，应该从自己做起，从小做起，使我们的地球妈妈越活越年轻，越长越漂亮，越来越可爱！让她分泌的乳汁越来越多，好让她的子孙后代越长越强壮！越长越健康！
我爱您——亲爱的地球妈妈！
保护我们的牙齿的作文英语【三】
现在，地球上绝大部分的水是不可以直接应用的。可以供陆地上所有生命使用的水还不到它总量的1%，但这也遭到了严重的污染，据资料显示，世界上80%的人生病与水有关，并且每年有2500万5岁以下儿童因饮用被污染的水生病而死。尤其是我国，污染更为严重，全国城市自来水源已有80%受到污染。我国每年因水污染至少要损失300亿元以上。
我们每天呼吸的空气也并不都是新鲜的。在城市里，汽车排放的尾气，工厂里冒出来的烟尘，垃圾燃烧的黑烟，路边烧烤和炒菜做饭等放出的油烟，都在污染着我们呼吸的每一口空气。
在我们外出旅游或游玩的时候，随处可以看到小塑料包装袋一类的白色污染，这些被随手扔在路边、江河湖海里，不易腐烂的白色污染，不仅污染了环境，还严重危害着人和动物的生命。在我国就曾发生过“国宝”大熊猫因误食塑料袋而死的事件。
在历史上，我国曾是森林覆盖率最多的国家之一，可现在，世界上要生产铅笔10亿支，其中有75亿支是我国生产的，单这一项至少要毁掉10万立方米的木材，现在，我国的.森林覆盖率不到14%。
同学们，珍惜纸张，就是保护森林与河流，所以，请大家不要随意扔掉纸张，完全利用纸的空白地方，浪费纸张就等于进入了砍伐森林的行业。还要拒绝那些随处散发的传单，这既浪费纸张，破坏森林，又会破坏城市卫生。另外，平时在外吃饭时，少用一次性筷子，这也是你为保护森林做出的贡献。
在我们外出游玩时，不要随地吐痰，不要随便损坏花草树木，不要随便采集标本，不污染水源，要少用一次性快餐盒，减少白色污染，垃圾要投放到指定地点，如果能骑自行车郊游的话，尽量骑自行车，以减少汽车尾气对空气的污染。
同学们，不要再污染我们的家园了，生病的母亲需要我们每一位同学好好保护，同学们，为了我们的地球母亲永远山清水秀，青春常在，从我做起，从一点一滴的小事做起，保护环境吧!

路旁一个小小的告示牌，上面写着保护环境、人人有责。但有些人把它看做天边一块渺小的石头，对它爱搭不理。而人们可曾想过如果连地球妈妈都不在了，那人类将要去哪儿住呢？
茂密的森林给地球妈妈增添了不少欢乐。但人类却对大自然是不闻不问，根本没有想过地球妈妈的感受。渐渐地、渐渐地这片茂密的森林被人们砍伐光了，只留下光秃秃的山坡……如果世界多了一片森林，地球就多了一道抵御风沙的.屏障；如果世界多了一片森林，地球将会变得更加美好……
人类的科技发展虽然越来越好了，但无数次不合理的破坏大自然；拿动物做试验，让有些动物为此失去了生命……
有些人肆意践踏小草，难道他们不知道小草也是一个小生命吗？如果你今天践踏了一棵小草，就等同于你毁了一个小生命。
保护地球，我们共同的宣言。让我们作出无悔的选择，发出惊天的呐喊！
