Environmental pollution is definitely a serious problem these days. But the government has consistently done more to strengthen its protection of the environment. Recently, a lot of chemical companies were closed to reduce the release of pollution. The country has also put a lot of financial resources into developing water purification and recycling systems to solve the problems of water pollution and shortages. And then there's all kinds of ``greening," and measures to protect the ecological environment are getting started. That goes to show that everyone takes environmental protection more seriously all the time. I think that as common citizens, I think we just need to take care of our own business. You can count that as making a contribution to environmental protection.
