Nowadays there are several opinions about the condition of our enviroment. Some people are sure that we have a great number of ecological problems, but others think that there is no danger for our planet.
Many people strongly believe that we have a lot of ecological problems. For example, they speak about the pollution of air and water, which hasa negative impact on animals, insects and people.
Nevertheless, some people are deeply convinced that we do not have any problems connected with enviroment. They also add, that they do not feel any danger, as people can invent technologies, which will produce all the natural resourses.
I personally believe that our planet is in danger. Air and water pollution will lead to the extinction of many species.
