  家乡环境的变化

    曾经，家乡被污染了，因为人们不爱环保了。
　　我看着蓝蓝的天空，想起以前的家乡，地上一点垃圾也没有，花儿每天高高兴兴的开放，小草每天开开心心的舒展。自从人们不爱环保后，花姐姐不想开放了，小草也枯萎了，不想再看家乡一眼。地上扔着太多垃圾，风吹来，风姐姐脸上都会沾满垃圾，所以风姐姐也不想来了。
　　家乡的街道上有很多垃圾，垃圾箱里却没有垃圾，只有地上有，因为人们把垃圾直接扔在地上了，所以垃圾箱只好委屈地空着肚子。
　　后来，家乡申办世界茶花大会，爱卫办的叔叔阿姨到处宣传“讲究卫生、人人有责”的道理，墙上那些五颜六色的广告语被清除了，街道上环卫办的叔叔阿姨每天都来清扫卫生，家乡变干净、漂亮了。
　　人们懂得爱护环境卫生，地上的垃圾没有了，小草身上不再有人践踏和丢垃圾，小花姐姐呼吸着新鲜空气，开得可绚丽了。
　　家乡的街道上再也没有人乱扔垃圾，风姐姐又穿上好看的衣裳，来到我们焕然一新的家乡。
　　我相信家乡一定会更加美丽，因为，我爱我的家乡！

家乡环境的变化

    我的家乡连云港原来是个美丽的城市，那里的河水清澈见底，小鱼和小虾在水里快活的游来游去。天空湛蓝深远，天上的白云一会儿像一只马，一会儿像一只羊，一会儿还像一只兔子……山上的树木郁郁葱葱，有许多可爱的小动物，有野鸡，野兔，还有成群结队的小鸟在树林里叽叽喳喳地叫着……

　　一年暑假，我回到连云港，清澈的污水变脏了，河水散发出阵阵臭味，令人做呕，以前清澈的小河没有了，小鱼小虾都死了。工厂越来越多，烟囱越建越高，散发出来的烟遮住了蓝蓝的天空，再也看不到蓝蓝的天空和白白的百元了。人们乱砍树木，山上的树木不断减少，裸露的土地不断扩大，野鸡野兔看不见了，小鸟也越来越少了……

　　人们看到上述情况，越来越严重，环境越来月恶劣，再不治理环境，人们就无法生存了下去了。于是政府决定治理排污，禁止乱砍乱伐，清理被污染的河道。于是，河水逐渐变清了，又能看到在和谁李游来游去的小鱼、小虾了。人们在裸露土地上中下一棵棵翠绿的小树苗，并在山上立了个标语牌，上面写着：“爱护树木，保护树木，多一片绿色，多一份生命。”禁止工厂乱排乱放，减少污染，天空又逐渐变蓝了，又能看到蓝天白云了。人们对生活垃圾通过统一案例处理，减少了白色污染。

　　我相信在大家的共同努力之下，我的家乡一定会找回昔日的繁华与美丽！

   家乡环境的变化　　

　　随着社会发展了，人们对物质的需求越来越强烈，谁不想多挣钱变成富翁？可是，现在社会上有些人光顾着挣钱，却把美丽的环境破坏了。比如我的家乡。

　　有一天，我回到久违的家乡时，被眼前的景象被震惊住了。

　　以前，我一回来，第一眼看到的是那一座座高大的山峦，漫山遍野都是绿色，空气清新甜润。那又长又宽的河，水是那样的清，清的一眼可以看到一群群不知名的小鱼来回穿梭。可是现在，山上的树木不断减少，裸露的土地不断扩大，河底的沙粒被挖土机挖出一个又一个的大坑。以前清澈见底的河水，被河两岸的石材厂排出的废水污染的又臭又黑。人们都不敢用河水浇菜了。听说，用河水浇的菜长的特别慢，种出来的菜也不如以前好吃了。

快醒醒吧！只为挣钱而破坏环境的人们。

　　我建议为了我们的健康，让我们一起张开双手，共创绿色的环境，让蓝天更蓝，让清水更清，就像爱护自己的生命一样爱护我们的地球。

   家乡未来的环境
    当看见美丽的花、翠绿的草、粗壮的树……看到这些景物时，你在心里想什么？一定在想家乡未来的环境吧！下面，我来为大家说说家乡未来的环境吧！
    在未来。你的家要在花园、公园等很多绿树旁，为什么？应为早上灿烂的阳光会照进你家里，如果有睡懒觉的小朋友，阳光会在你身上爬，吹着你早早起床锻炼身体。
    在炎热的夏天，你是否想在大树下乘凉？那你要去公园喽，当你走在郁郁葱葱的树林中，你一定会说：“哇！太爽了！”。对呀，你不仅可以乘凉还能野餐呢！
    花朵儿就不用说了吧！那花园里一进去，迎接你的是一大坛鲜花，中间红外边黄，美丽极了！向左走，一路五光十色的花开得整整齐齐。在花园的尽头，长着无数数不清的花，红的花、黄的花、緑的花…..五彩缤纷！
    那时候，小骄车一律“退休”，大家都坐超级环保车。车子结构是：车轮装有超小吸尘器，还不会让车轮开不动，主要是把地上的灰尘吸掉，变成环保汽油。在车子里的椅子，是一种会有吸垃圾的椅子，比如有小朋友吃零食时会掉一些渣子，它马上会吸收掉，变成环保汽油。它还能帮大家呢！比如现在是夏天，它会变成放冷气的椅子！喇叭嘛，不再像现在的车子一样，发出的是噪音，而是优美的歌曲，让人听起来心里爽爽的！如果路脏了，除了能吸尘还会将马路清洗一遍呢！
    看，家乡未来的环境怎么样？这种环境十分难得，大家一定要爱护，不然未来就是一片空白，只有哭泣声。树没了，草没了，花没了，水没了……大家要开始保护环境，留住欢声笑语、花草树木！
   赶快行动起来吧！
