NO.1:垃圾分类 n美国所在小区每周星期5定期来收 垃圾的.清晨，各家各户把垃圾桶 分类放到门前，由环卫部门的车辆 拉到处理场进行集中处理。不可再 利用的变成肥料，然后免费给各家 培植树木花草。 NO.2:纪念的方式 n很多美国人纪念亲人的方式,是在路边为他们种上一颗树, 或者捐赠一条木椅,既方便了他人,又纪念了亲人.每当我看 到路边这样的石头,看到大大小小的树,我都很感动,那些离 去的人们,他们的生命也随着这些树而永生了. NO.3:路边到处有供收集狗粪的袋子 n美国人爱养狗,但 是路边从来没见过 狗粪.除了美国人 自己有良好的习惯 外,与路边常见的 狗粪收集设备也有 关.几乎每个草坪 旁边都会有几个这 样的盒子. NO.4:环保组织经常会有活动,宣传 环保意识 n环保局经常会搞一些有奖问答活动.回答了他们提 出的各类环保问题,就可得到相应的奖品.大家都很 喜欢这样的活动. NO.5:鼓励回收 n美国环境保护局成立“美国回收利用日”组织，将每年的 11月15日定为“回收利用日”。美国各类环保组织经常举 办各类活动，鼓励居民积极参与社区里的再生物质利用项 目，购物时使用可循环利用的包装品，购买可以维修和重 新使用的物品等.几乎所有的瓶子上都有回收的价钱.易拉 罐,啤酒瓶,饮料瓶等都是可以退钱的.而且很多超市都顺便 有退瓶子的点,很多还是自动的. n一瓶矿泉水1毛钱,瓶子5分钱. NO.6:垃圾处理机 原来这是一个处理生活垃圾的装置,从上到下四层. 原理是 利用蚯蚓来消化生活垃圾.很奇怪,原本以为不打开的时候闻 不到臭味是因为密封的,可是打开后也没有异味. 这是最后一层,经过处理,那些垃圾已经变 成这样了,非常的肥沃了吧. 当然最肥沃在最下面,打开笼头流出浓浓的汁,这 是最肥沃的肥料. We all live on the earth. It is our home. Our earth is beautiful. We should care for it. And we should do something good. We should make the air clean. We should plant more trees. We should help the animals. We have only one earth. We have only one earth.
