当你倒下垃圾时，你想过吗，在这短短几秒钟，将产生多少垃圾？据1979年统计，全国城市垃圾的清运量是2500多万吨，1996年城市垃圾的清运量是1、16亿吨，是1979年的4倍。

而现在已经是2012年了，我们的垃圾清运量该到达一个怎样惊人的天文数字！就拿我们村来说，村里的环卫工人告诉我，他们一天要打扫大半个社区，光是倒在垃圾桶里的垃圾，同事们就要拉好几车，一天下来，垃圾不下十车。有时候，垃圾散到别处去还要再捡起来。垃圾有异味，本身就很难消除，丢弃到不能监管的地方就更难控制了。

虽然这些垃圾在一些城市基础较好的地区，大部分会得到卫生填埋、焚烧、堆肥等无害化处理，但是更多地方的垃圾则常常被简易堆放或填埋，导致臭气肆虐，并且污染土壤和地下水体。据环卫工人爆料：垃圾无害化处理的费用是非常高的，根据处理方式的不同，处理一吨垃圾的费用约为一百至几百元不等。人们大量地消耗资源，大规模生产，大量地消费，又大量地生产着垃圾。

难道，我们对待垃圾就束手无策了吗？其实，办法是有的，这就是垃圾分类。垃圾分类就是在源头将垃圾分类投放，分类收集，并通过分类运输和分类处置使之重新变成资源。

Have you ever thought about how much garbage will be produced in just a few seconds? According to the 1979 statistics, the total volume of municipal waste in China is more than 25 million tons. In 1996, the urban garbage volume was 1, 1.6 billion tons, four times that of 1979.

Now that it's 2012, we're going to have a staggering astronomical amount of garbage. In our village, the village of sanitation workers told me that they want to clean the better part of a community, a day just pour the garbage in the dustbin, must pull several colleagues, the end of the day, waste more than ten cars. Sometimes, the garbage will go away and be picked up again. The smell of garbage can be difficult to eliminate, and it is harder to control where it is not regulated.

Although these garbage based good areas in some cities, most will get sanitary landfill, incineration, composting disposal, such as waste, but more places have often been simple and easy to pile up or landfill, cause odor, and contaminated soil and groundwater. According to the sanitation workers, the cost of garbage disposal is very high, and the cost of handling a ton of waste is about 100 to several hundred dollars depending on how it is handled. People consume resources, mass production, mass consumption, and mass production of garbage.

Isn't there anything we can do about it? Actually, the method is some, this is garbage classification. Garbage classification is the source of garbage classification, classification and collection, and by classification transportation and classification disposal to make it into resources.
