Environment-SLV

There are two kinds of environments.Example good and bad environment.There are many small kind in the bad environment like air pollution and water pollution.
First part i want to introduce about air pollution. Each country has their environment, some are good and bad such as Cambodia there are good and bad environment in there. Because in Cambodia many people do not care about environment . Some factories built near the town so,it polluted bad air.In the city people always go to work by car,they didn't use bus or train and there are lot of traffic jam, so in the city polluted by car or motors. But in some countries such as Australian or American some people went to work by train or bus to work so it helped to reduce using car in the city, then there weren't more air pollution in those country
Second i want to introduce about water pollution, because i think that is one of the special or important kind of environment. If people drank dirty water from pollution, they will get illness, diarrhea. Because in dirty water has bacteria and maybe contagious disease too. When the people threw rubbish in to the river or lake, Then the water become dirty and can't drink it so they need to clean it first by using electric and cost a lot of money. But i think if we don't want to spend money, we have to take care water, don't throw rubbish in the lake or river and put the rubbish in the bin.
