Pollution is a serious problem in our society. We are polluting our oceans, air, earth, plants, ... and this has a lot of bad effects for our health, and for animals and plants.
I have read that there is a lot of pollution in some countries, especially in China. People can't breathe normally and they have got a lot of respiratory problems. This is because there are a lot of factories polluting the air every day without control. China is becoming a very rich country, but people are dying because of the pollution.
In Spain, we have a lot of polluted cities, for example, Madrid and Barcelona. Also, we have now this problem, and some city councils are trying to control the traffic in the cities.
If we don´t do anything quickly, we or our children will die very soon.
