It is urgent to have a survey that is close to the lives of college students

Investigation of environmental pollution by chewing gum.

1. Purpose of the investigation.

Nowadays, chewing gum is considered by some people to be a fashion, whether it is on the street, in the park, in the theater or in the school, you can often see some ladies, gentlemen, students and young children"Chic" "Comfortable"Chewing on the ground. After enjoying it, I inadvertently vomited, and the problem came, the residue was very sticky in the mouth, spit on the floor, and the wall was also very sticky. As a result, they clinged to the ground and were stepped on a few more times, causing pieces of pollution.

This kind of pollution is not as disgusting and conspicuous as the atmosphere, water quality, and noise, nor is it as obvious as waste paper, dirt and other garbage to be removed. It's inconspicuous, but it can make you sick at times (I once sat on a public chair with three pieces of gum residue stuck to it), and it's a real pollution. For this reason, we investigated this kind of chewing gum that everyone can eat and hardly pay attention to where it goes.
