一篇介绍地球的英语作文【一】
每个人都有自己的家园，森林是野生动物的家园，池塘是小鱼儿的家园，天空是小云朵的家园，而地球是我们人类共同的家园。
地球给了我们水源与森林，给了我们美丽的环境，也给了我们清新的空气。可我们人类又是怎样对待自己的家园的呢?
听爸爸妈妈说，以前的地球是很美的，到处山清水秀.鸟语花香，空气十分清新，使人心旷神怡。可是现在，地球变成什么样了呢?由于人类的自私自利，他们对森林.水源巧取豪夺，毫不珍惜，慷慨大方的挥霍，而且滥用化学药品，造成一系列的生态灾难。据我所知，目前全世界的工厂和电厂每年排入大气中的二氧化碳有50亿吨;二氧化硫.碳氧化物等有害气体的排放量也相当大。进入大气中的废气种类很多，已经产生危害而引起人们的注意的就有一百多种。大量的废气进入大气层中，必然破坏大气原有的化学组织和性质，对人类的环境产生很大的危害，它能让我们患肺癌而，使全球面临变暖危险，使冰山融化，使整个地球秃顶既减少，使大量农作物随气候变化而迁移，造成许多农作物减少。总之，大气污染对于人类是一场大灾难.
保护环境，人人有责!我们现在虽然还只是小学生，不可能为全人类的环境作出特别大的贡献，但我们可以从身边的小事做起，从保护学校的环境做起。同学们，我们是21世纪的主人，环保意识是现代人的标志。我们要有时代责任感，为美化校园净化校园作出我们应有的努力，“勿以恶小而为之，勿以善小而不为”，让我们共同努力，保护珍爱地球——我们共同的家园，让清风常拂绿柳，碧水永伴苍山!

I have a great mother. She cares much about me in my life and study.
