Since July 2019， Shanghai has been the first city to sort their garbage．Staring on May 1"．2020， Beijing also became one of the members by introducing a new garbage sorting policy．Green garbage has come to China．

In the past， people put a lot of garbage into one pile and then took the garbage to landfill sites．These landfill sites， however， could pollute the land and water． So， if we can find ways to reuse or recycle more garbage， then we will cause less pollution．

The new plan asks people to put their garbage into four different boxes， one for each type of garbage． The brown box is for "wet garbage" （such as food and drink waste）， The red one is for harmful waste （such as batteries and electronics）． The blue one is for recyclable things （such as paper and plastic）．And finally， the black one is for"dry garbage" （everything else）． This "sort your garbage" plan is the same as other plans used by cities around the world． These plans have been very successful． In Canada， it's expected that 85% of plastic will be recycled by 2025．

Why should we sort our garbage？The reason is that we are producing increasing amount of waste every year．It's reported that Chinese cities produce over 200 million tons of waste each year．Reducing that amount will surely help the environment．

However．the garbage sorting is a long journey as it takes time for people to learn and form a habit．More cities are on their way．By 2005 ，it's hoped most Chinese cities will complete the building of garbage sorting．
