人类只有一个地球,它是人类赖以生存的自然资源,人们要过上幸福美好的生活,就必须自觉地保护自然环境,爱护地球。
然而,近几年来,地球的环境却越来越恶劣:全球性气候变暖,飓风、暴雨等灾害性天气频繁出现,“非典”、禽流感等传染性疾病时有发生,给人类的生活和工作带来严重威胁和许多不便。这些都是人们不断地“伤害”地球的结果。大片的.森林被砍伐,碧绿的青山被挖掘,美丽的草原成荒漠,清澈的河水成浊流。树林少了,青山秃了,草原荒了,清水黑了,使人们生存的环境变坏,呼吸的空气变差,生活的环境被许多有害的东西所“侵占”,病毒就趁机钻进人们的体内,我们人类就会患上一些可怕的疾病。
前几天,我在报纸上看到这样一幅漫画:一个人坐在树梢上,正在砍他坐着的那根树枝。“哼,真好笑。”有些人可能会这么想。难道你就没有想一想,这仅仅是幅好笑的漫画吗?它不正是在讽刺我们吗?难道你就没有悟到,它在警告我们:人类在破坏环境的同时,也在不知不觉地伤害自己。
当你走在大街上,如果你想吐痰,你会怎么做呢?如果你选择了吐在地上,那么你想过没有,你在害自己吗?一口痰含有大量的病菌,当太阳着时就会繁殖、传染。同样,当你砍伐一棵树,当你挖掉一片草,当你把脏物倒进河流,难道你没有觉得这是在破坏环境,“伤害”自己吗?
俗语说得好:“前人栽树,后人乘凉”,前人给了我们大片大片的森林,绿地,我们留给后人的是什么?是光秃秃的荒漠,还是茂密的树林,你肯定选择的是茂密的树林。那还有什么犹豫的,让我们大家一起自觉保护环境,自觉爱护环境,自觉绿化环境,改善我们的生活环境,创造美好的未来!

春天到了,阳光明媚,鸟语花香。小晶和小和华放学路过一座居民楼时,看见这里的垃圾筒旁堆满了垃圾。小晶对小华说:“我们把垃圾收拾干净吧!”小华想了想说:“好吧,但是我们这次收拾好了,可下次还有人把垃圾丢在垃圾筒旁,那可怎么办呢?我看这样吧,你去收拾,我想想有什么办法可以提醒大家不乱扔垃圾。”于是小晶一点一点地把垃圾捡起来扔进垃圾筒里。这时,小华也想好了办法,他拿出一张纸,在上面写下几个大字:文明——只差一步。小晶终于把最后一点垃圾收拾好了。他们把字条粘在垃圾筒上。从此,这里再也没有人乱扔垃圾了。
看了这幅漫画,我觉得那些乱扔垃圾的人实在是太可恶,太缺德了。他们为了图一时的方便,随意地把垃圾扔在地上,严重破坏了这里的环境卫生。这种行为会遭到谴责的。
在我们的生活中,也有这种不文明的行为。记得在我读二年级时,我们班上的一位同学把削铅笔的木屑当作“天女散花”来开玩笑,我对那位同学说:“你这样做,那负责扫这块地的同学该多累啊!”可那位同学却说:“你玩你的,我玩我的,咱俩互不相干,你管得着?”至今这种恶劣的行为还在我们的校园里继续。
人们啊!觉醒过来吧!我们的地球在一天天衰老,如果我们再这样破坏环境,大自然就会报复人类,如大气污染﹑酸雨﹑沙尘暴等灾害,严重威胁人类的生命,地球将走向毁灭。住手吧!人们!我们只有一个地球,如果不善待地球,我们将失去生活空间,行动起来吧!保护环境,为建设美好的家园献上我们的一份力吧!
