Pollution is a very big problem. Now we produce a lot of industrial waste and gases that are poisonous and pollute the air we breathe. The most important kind of pollution is air pollution that can provoke acid rain. A solution of this problem can be the will of politicians,scientists and legislators to work together.
GLOBAL WARMING.
Temperature is increasing in the earth and this is due to the fact that greenhouse gasses let solar radiation enter our atmosphere but they don't permit the flow of infrared radiation, producing the warming of the earth.There are some evidence of this in thi rise of sea levels over the past century. Some scientists are afraid for an increase of desease in human beings and animals for the future but others are not alarmed.
