Horrible condition of nowadays ecosystem is one of the most topical global problems. A human has spent almost 2 millions of years, fighting for survival against powers of nature and hundreds of creatures… Now he has been being the master of the planet for almost 300 years, and he has already managed to put the Earth on the verge of doomsday.
Horrible condition of nowadays ecosystem is one of the most topical global problems. A human has spent almost 2 millions of years, fighting for survival against powers of nature and hundreds of creatures… Now he has been being the master of the planet for almost 300 years, and he has already managed to put the Earth on the verge of doomsday. If we want to save our fragile planet, we must stop being so injudicious, short-sighted and intemperate.
Today we can observe that all types of pollution are increasing with
horrific quickness. It’s well-known, that our land is horribly polluted.
We all can see thousands of huge dustbins and we all see heaps of litter
in the streets, beaches and forests every day. But we all keep throwing
rubbish! The only way to solve this problem is to start recycling in
production quantities. Only this can help us to reduce the amount of
litter, save energy, money and important raw material resources. We
just need to spend some money now for building recycling and sorting
factories, and in 3 or 5 years, they’ll requite with interest! As
tons of glass, paper, polyethylene, plastic and tin will be earned.
Another burning issue is water pollution. Our industry has developed
greatly, so today the factories are poisoning water on a global scale.
To stop it, we can only perfect our technologies.
Of course, a very important problem is air pollution, which leads to
green-house effect.To my mind , to stop this problem , we have
to start doing new factories , which will be more safely for environment
.
Deforestation threatens our nature as well, as it usually leads to desertification.
Moreover, forests – especially those huge forests of Siberia
- adsorb carbon dioxide and give out oxygen. And rainforests are home
to half of world’s animal and plants. I’m absolutely sure, that
if we don’t stop cutting them down, our planet will become unsuitable
for life.
We must also work harder at endangered species’ protection, restriction
of the noise pollution and lots of other problems, as well. As we know,
all issues in our environment are interconnected. Deforestation leads
to erosion and famine; land pollution results in air and water contamination
and they activate El Nino, which causes global changing of the climate
and melting of polar ice. And these phenomens are the reasons of such
eerie diseases as droughts and famine, floods and frosts, forests conflagration
and hurricanes. They all take off thousands of lives… So we ought
to start changing ourselves and our attitude to our planet right now,
or it’ll be too late to save us…
