The Pollution After 2007

We watch a movie on our biology class and it told us the bad pollution in this world. However the movie stopped in 2007, so I looked some information form the internet and the newspapers about how is the pollution going after 2007.

When we read newspapers, we often come across the word pollution. This word was not familiar to the people some decades ago. But now, it is a serious threat to us because it means the poisoning of the air, seas, rivers and lands, which would do harm to our health.

There are many factories that bring pollution to u s. We can’t have fresh air in the morning. This is mainly because of the poisonous smoke coming from factories, especially chemical ones. In the rivers, seas and oceans, there are industrial wastes. Some factories just throw their wastes into seas or let them flow into rivers. When people drink the water from such rivers, they get poisoned. Besides, there is rubbish from ships and when sometimes an accident occurs in an ocean, oil flows out from tankers.
