1. 
   An interview of a famous environmentalist.
   
2.

    Listen to the report on the protection of biosphere and be ready to support or contradict the scientist’s argument that “we are polluting ourselves out
    

_#of existence”:
Dear colleagues! 1 appreciate this opportunity to talk about ecological problems in your country where enviromental protection is the constitutional duty of every citizen.
Interrelations between man and the biosphere are of a very complex nature. Man, like every other living organism, depends for his life on what the biosphere provides: water, oxygen, food, etc. On the other hand, the biosphere is strongly affected by all sorts of human activities. The conflicts that arise in this man and the environment interaction are different. For example, man creates new compounds, new substances, pure chemical elements which are unknown to the biosphere. They do not belong to the natural cycle of matter. They undermine the capacity of natural complexes for self-regulation. Though not changing biologically, we change the medium in which we live. We are polluting ourselves out of existence.
Forests are disappearing. Deserts are advancing at the same speed and, if there are qualitative changes in the biosphere, it will no longer correspond to the biological requirements of man, whose ability to adapt is very limited.

Your great scientist Vladimir Vernadsky was the first to realize the necessity for quite a new approach to the biosphere as early as the midforties. It is Vernadsky’s concept of the biosphere that we accept today.
That we must act now is clear. If your house is in order, you’re all right. And I would like some of the Russian environmentalists to share their experience and speak about how environmental protection is organized now in Russia.
