With the development of science and technology, we are enjoying a better life than before. However, for a long time, our environment has been damaged because humans have been careless. People have harmed nature through agriculture, fishing and tourism. And the problem of “white pollution” caused by used plastic is becoming increasingly serious. We still have a long way to go to solve all the problems. But all of us should do our part to protect the environment, such as using own bags instead of plastic bags and leading a low-carbon life.
