Destruction person over the last 50 years

Humanity over the past 50 years has destroyed 90% of the world's large fish stocks
22% of the known fishing areas of the ocean are quite depleted or overwhelmed by overly zealous exploitation,
and another 44% were on the verge of exhaustion.
Catching edible fish species, we throw away each year of the networks back into the sea 27 million tons of other animals - as a rule,
in the non-viable state.
The seabed in many areas of the ocean so plowed trawls that has nothing on it can not live.




Over the past 50 years, man has destroyed 70% of the world's forests.
About 30% of the world still remaining forests are fragmented and degraded into pieces and cutting them goes at the speed of 50 square miles a year.



More than 45 thousand lakes
Each year, the chemical industry produces more than one hundred million tons of 70,000 different organic compounds,
and each year added to the range of about a thousand new substances.
Only a small fraction of these chemicals thoroughly tested for harmless to humans and the environment.





Over the past 50 years, man has destroyed a quarter of all species of birds, 11% of the rest - on the brink of extinction.
Extinction, moreover, threatens 18% of all species of mammals, 5% and 8% of fish species.



Coral reefs, the most diverse of the water systems in the world, suffer from overfishing,
pollution, epidemic diseases and rising temperatures.
