The pollution of China

When you go to a city in China, such as Beijing or Hebei, you hear noises everywhere... You hear people talking, cars going by, and  sense delicious smells of rice and meat. However, you cannot but notice something strange.  You cannot see very well because of the fog. After a long day outside you start coughing and get a sore throat. You are astonished after you realize that it was just the incredible amount of pollution . And not only the air is polluted, but water as well. As you see in this picture many fish have died because of the incredible amount of pollution. Why so much pollution here? Since hundreds million of people live there, there is more people polluting than in a small town. As the population grows, so does the pollution. It affects the people that live there, animals and plants.

As you can see causing more pollution will cause more harmful disturbances. What do you think we can do to stop polluting the environment, especially in highly populated areas?
