Environmental protection is the work of the workers, but it is everyone's common responsibility. To protect the environment, we should not litter indiscriminately and have to help the janitors to clean up the garbage, which is an environmental protection issue. If you litter indiscriminately, it will pollute the environment, turn to the problem of respiratory prevention, then we have to wash our hands with soap, then, wear a mask, avoid being close to infected people and avoid gathering prace in a crowded place
