| Nature on our planet was once wild and rebellious.
Forests and impenetrable jungles grew everywhere,
rivers were full of water, and the lands were not
plowed and fertile. Animals grazed in herds on the
plains, and the air was exceptionally fresh. But
then people appeared on earth, and everything changed.
Man began farming and domesticating wild animals,
fishing and hunting. At first it didn't break
the harmony. Animals also feed on plants and hunt
each other. They drink water and build their homes.
But over time, the earth's population grew. Therefore,
people needed more trees to build their homes,
and we began to cut down forests. We needed coal
for heat, and we started digging it out of the
ground. People began to sew clothes from animal
skins, and use water not only for drinking, but
also for watering fields, cooking.
With the development of civilization, many environmental
problems have arisen. Firstly, there was a thinning
of the resources of our planet. Secondly, the
environment has become polluted with waste. The
earth's climate has changed which has led to an
increase in the number of natural disasters and
put people at risk of destruction.
Modern scientists are constantly trying to predict
when the end of the world will come. They calculate
the risks, look for ways to save our civilization
and solve existing environmental problems.
Of course, there is no threat to our generation.
I think we will live our lives peacefully and
happily in harmony with the world around us. But
it still makes me sad that people realized so
late how important nature is to them. They realized
that it cannot be completely subdued. And only
now we began to take care of it and protect it
from destruction.
