Human activities have become a key reason that from 1970 to 2012, the number of vertebrates on Earth has declined by 58 percent. This subtype combines the most difficult organized organisms on Earth — mammals, birds, fish, amphibians and reptiles. That vertebrates on the planet is rapidly getting smaller, according to a report, prepared by the world wildlife Fund and the Zoological society of London.
The collected data on 3 706 species and came to the conclusion that due to the loss and degradation of habitat, as well as some other factors, the number of vertebrates on Earth has declined by more than half. First affected animals that live in fresh water — has been reduced by 81 percent, i.e. five times. Populations of terrestrial animals and inhabitants of the World ocean has declined by more than a third.
Analyzing existing trends, experts come to the conclusion that by the end of the decade the number of invertebrates on Earth could be reduced by 67 percent compared to 1970. On the other hand, experts say that to lose hope humanity is not worth it — if in the near future will take the necessary measures for the protection of nature, the situation, in all probability, stabiliziruemost. In particular, scientists call for humanity to pay more attention to the development of “green” energy and the conservation of forests and other natural habitats of wild animals.
Experts also mentioned that the researches of geologists testify to the “official” joining of the Earth the anthropocene is the period when the influence of the impact of human activities on the planet in many ways is becoming a decisive factor influencing the fate of many ecosystems. The term “atropatan” has long been considered rather informal, but some experts say that in the middle of the last century, on the accession of the planet into a new geological epoch, one can speak of objective fact.
