It was during the last 50 years, humans especially active towards environmental disaster. Many natural resources, as well as supplies of water and food are on the verge of exhaustion.
1. 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 even 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 - usually already in a state of non-viable.
The seabed in many areas of the ocean so plowed trawls that has nothing on it can not live.
2. Over the past 50 years, man has destroyed 70% of the world's forests.
About 30% more of the remaining forests in the world fragmented into pieces and degraded, and cutting them goes at the speed of 50 square miles per year.
3. More than 45 thousand lakes
Each year, the chemical industry produces more than one hundred million tons of 70,000 different organic compounds, and annually to the range is added about a thousand new substances. Only a small fraction of these chemicals thoroughly tested for harmless to humans and the environment.
