Primary school students give environmental advice to the mayor

Mayor Uncle:

I am a primary school student in Huaqiangguo.

I grew up in Nanning and how Nanning changed. I saw it. From an unknown city to a green city in China, the Folk Song Festival was launched, and the South Expo...

Now in Nanning, you can see the words “Environmental protection, everyone is responsible.” On the side of the road, all kinds of trash cans are beautiful. Recently, everyone has advocated the separation of recyclable and non-recyclable trash cans.

However, I don't think it is okay to classify light. I want to write some kinds of garbage that can be recycled in the trash can and a kind of garbage that cannot be recycled. Not everyone wants us to accept more knowledge, know what is recyclable and not. What is the recycling of garbage, think of those migrant workers, they do not know, they will be littered, this is not good. Not only will it not be able to play the role of environmental protection and garbage classification, but it will bring trouble to the workers of those garbage dumps.
In addition, I also found a very serious problem.

One day, I went to the bus with my mother and I wanted to go to the Martyrs Cemetery to sweep the grave. At the beginning, we were very happy to go out, but when we went to the bus station and waited for the bus, we found a trash can next to it. The garbage inside was stinking. The passing pedestrians went around with their noses. We walked. After a while, I will smell a big rancid smell.

Later, when I went to the place where I had a trash can, I carefully observed whether there was any smell. After a period of observation, I found that the garbage bins are now fixed. Unlike the previous ones, the garbage can be dumped, but why is it stinky? ? Later, I realized that it was because the garbage bins were fixed. When the sanitation workers cleared the trash cans in the morning, they simply dumped the surface garbage and did not clean them to the bottom. Once, I went to ask them why they didn't clean up the garbage. They said that they didn't want to, because the trash can was fixed, so the hand could not reach the bottom, and the garbage could not be poured out, so the garbage could only be left inside.

It can be seen that the trash can smells not because the sanitation workers are not responsible, but because the design of the trash can has problems. I hope that in order to be beautiful in Nanning and to refresh the air, please ask the uncle of the mayor to design some trash cans that are both practical and good-looking. Don't let those smells pollute our fresh air.
