^13^ Enviromental problems

Last month, we watched a video. The name is “In Convenient truth”. It is about Global Warming, but I think the Global Warming is one of the effects; the same as the population of the earth, it is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly. Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people. I hope people will be awareness of these negative effects, and let’s protect our earth.
