Hi everyone! Today i would like to talk about very important things nowadays - Environment problems. 

Today, the contradictions between man and nature have acquired a dramatic character. With the development of civilization man’s interference in nature has increased. Every year the world’s industry pollutes the atmosphere with millions of tons of dust and other harmful substances. The seas and rivers are poisoned with industrial waste, chemical and sewage discharge. People who live in big cities are badly affected by harmful discharge from plants and city transport and by the increasing noise level which is as bad for human health as lack of fresh air and clean water.

I used Prezi to create presentation for you, so please, watch it and make the conclusions, let's help our planet, our home. ( https://prezi.com/p/qcd9arszrydy/ )
