Nowadays, the environment is polluted, so what should we do to protect the environment ? Firstly, we shouldn't throw rubbish into the river or the beach. Beacause if we don't do that, all the fish and aquatic animals will die. Secondly, we should use public transports such as : bus, train, ... instead of private transports to reduce smoke. Thirdly, I think we need plant more trees because the trees make the air cleaner. In short, we can protect the environment by that ways.
