About a century ago, man had used only 15 percent of the Earth’s surface.
Scientists of the University of Queensland (Australia) came to the conclusion that the places on Earth where wildlife is preserved, is rapidly disappearing.
According to the researchers, about a century ago, man had used only 15 percent of the Earth’s surface to growing crops and livestock. Currently, human activity affects 77 percent of the land area, including Antarctica, and 87 percent of the World’s oceans. In the period from 1993 to 2009, human settlements, agricultural lands, and the industry has taken 3.3 million square kilometers of undeveloped areas.
However, the polar regions remain the most not affected by shipping, pollution and fishing regions of the ocean. The remaining natural ecosystems can be maintained only if countries recognize their significance and take joint efforts for their protection. At present, many protected areas in the world not officially defined, unmapped and not protected at the legislative level.
