Our environment has become seriously polluted. Why? What can we do?

First of all is air pollution, they came from smoke we burned out and motor vehicles we use. To reduce exhaust fume and smoke, we now can use electronic stove or electric vehicles, or simpler, we can use public transportation such as buses 

Secondly, land pollution.  They come from the reasons that we throwed trash on somewhere that is not in the bins or we hidden it in the ground. A lot of countries has banned people from these behaviors by fined them heavily. Vietnam haven't done this so seriously yet but we all have to have awareness on this thing. We also can volunteer to clean the environment or recycle them to make some lovely and creatively souvenirs (we can sell them too).

Lastly, the water pollution. This is because the factory pumbed waste water into the rivers, lakes or seas. Only the government can ban or fine them. We also can help something by report them to local authorities and save water
