Humans & the environment
Since ancient times nature has served man, being the source of his life. For thousands of years people lived in harmony with environment
But with the development of civilization man's interference in nature began to increase ...
Large cities with thousands of smoky industrial enterprises have appeared all over the world today.
The byproduct of their activity pollutes the air we breathe the land we grow grain the water we drink
And all the atmosphere
Vast forests are cut and burn in fire
As a result ...
Some species of animals,
fish and plants
disappear forever ...
a number of lakes and rivers dry up
We faces many ecological problems
The environment is so beautiful! We should preserve it!
