In China, people
are polluting the environment with toxins that cannot be absorbed naturally. For
instance, a lot of poisonous smoke and waste water come from plenty of chemical
factories. When people pass by a chemical factory, they always can see lots of
smoke coming from its smokestacks
dirty the air. Nowadays, the sky is not as clean as before. Moreover, many
chemical factories just dump waste water straight into the river without any
treatment. It causes serious water pollution. Dirty air and poisonous river have
made thousands of Chinese people live in a terrible environment which is harmful for our
health.
