There is no doubt that the environment isin trouble.Factories and motor vehicles burn fossil fuels which pump out toxicemissions.At the same time ,contaminated gases rise into the air and leads toair pollution.River and soil contamination stem from industrial waste andexcessive use of fertilizer.
It is high time that we could take steps toavoid environment being deteriorated.
As for me ,I think litter classification isof great significance.
I mean to put it another way,garbage is necessarilyto be classified as recyclable and unrecyclable one.Apart from that ,weshould carefully deal with toxic waste.Such battery,pigment,skin care orother chemical substance are supposed to be sealed in the bag.And then dropthem in grey trash bin.
On top of that ,kitchen waste like leftover,cans and bags should also be packed rather than be threw thoughtlessly .It isslightly different from toxic waste .It is supposed to be threw into greentrash bin.
Anyway,individuals also can docontribution to respect environment more or less.
We should enhance the awareness ofenvironmental protection and advocate a environmentally friendly lifestyle.

·The use of some nonrenewable tinsand bottles is unavoidable ,but those who use these resources must strive to conserve ,reuse and recycle them andthus extend their availability.毫无疑问，环境面临问题。工厂和交通工具燃烧的化石燃料排除有毒物质。同时，污染气体进入空气，导致空气污染。河流和土壤污染也由工业污物和肥料过量使用引起。

对我来说，我觉得垃圾分类很重要。我是说，垃圾应该被分为可回收和不可回收的。此外，我们应该小心处理有毒垃圾。比如电池，过期药，护肤品和其他应该被封好装在带子里的化学物品。另外，厨房垃圾，比如剩菜剩饭，罐和带子应该被包好而不是乱扔。有别于有毒垃圾。我们应该将之扔入相应的垃圾桶。

总之，人们应该对环保做出或多或少的贡献。我们应该提高环保意识和提倡环保的生活方式。
