    You might not think much about where your garbage goes. But now you might want to know. On July 1, Shanghai introduced a new garbage sorting policy. People there need to put different kinds of garbage-wet, dry, recyclable and harmful, into different dustbins. Other cities in China will do the same soon.

    Why is garbage sorting a big problem? It's because there is too much garbage these days. It is bad for our soil, air and water. Actually we can make use of some garbage again. And first, we need to sort our garbage.

    Four kinds of garbage in Shanghai

Harmful garbage	Recyclable garbage	Wet garbage	Dry garbage
lamps, batteries, nail polish （指甲油） and other things with harmful chemicals.	Paper, books, boxes, glass bottles and newspapers.	Food, vegetables, flowers, leaves and Eggshells （蛋壳）.	It includes pens, toilet paper, tape, hair and towels （毛巾）.

    Recyclable garbage includes paper, books, boxes, newspapers, and glass bottles.

    Harmful garbage includes lamps, batteries, nail polish, and other things with harmful chemical (有害化学物质). Wet garbage usually comes from the kitchen, such as food, vegetables, flowers, leaves and eggshells.

    Dry garbage is anything you cannot put into the other three bins. It includes pens, toilet paper, tape, hair, and towels.
