A chemical factory lies near my home. The manager of the factory was criticized by the government because the factory gives out lots of harmful smoke on every day, but he paid no attention. Then the factory was forced to stop production and the manager said angry, “Is there any evidences to show that we did harm to people’s health? In fact, we didn’t.” Just then, doctor came, with the result of the medical exam, say the manager was suffering from lung cancer. That is very clear that the pollution has harmed not only the people around the factory and also the manager himself. The manager regretted having caused so many pollution.
