Researchers have concluded that over the past hundred years, the main way thanks to human destructive pace the extinction of various species of animals accelerated 114 times. it means that the number of animal species that have disappeared over this short time span for natural extinction rates it would take more than 11400 years.
The main cause of the mass death of these animal species is human activities that lead to pollution, loss of environment habitat, increased carbon emissions, climate change and ocean acidification.
Since 1900, more than 468 vertebrate species have become extinct. animals, including 80 species of birds, 69 species of mammals, 24 reptile species, 158 species of fish and 146 species of amphibians. At the same time, when natural selection would have to disappear only 9 species animals …
Each of these extinct species played an important role in ecosystem, and regardless whether it was in the upper or bottom of the food chain. This fact has a very negative effect on environmental situation in general, undermining our Of the earth!
Researchers typically label a mass event extinction when more than 5% of species die on Earth short (in the geological sense) period of time, beech A. Based on the analysis of fossils, researchers are aware of 5 mass extinctions, the last of which occurred over 65 million years ago when an asteroid destroyed almost all types dinosaurs. Without a doubt, a new study demonstrates that now we are entering the era of the sixth mass extinction.
If humanity moves this way very soon a huge amount of biological diversity will be lost, and Earth will need millions to restore lost ecological balance years.
For example, today the snow leopard is on the verge of extinction, since as a result of poaching and loss of habitat for the last 16 years, the number of this species decreased by 20%. Not lagging behind leopards and reducing the population of elephants, lions, cheetahs, rhinos, jaguars.
However, scientists believe that there is still time to save wildlife! To do this, work on the quality of protection nature at state political levels. To avoid disasters, rapid and massive intensification of efforts to conservation of endangered species. In particular, it should be decided issues related to the over-exploitation of these species in order to economic benefits, habitat loss, pollution environment and climate change.
