The diversity of life on Earth is not a trivial matter. Plants and animals somehow help a person to maintain health and serve as a source of human well-being. Meanwhile, in recent years, there has been an unprecedented rapid rate of loss of biodiversity: from coral reefs, to rare species of tigers and birds, many species of plants and animals are on the verge of complete extinction.

"To save any endangered species, first of all, you need to protect its habitat, but 43 percent of such areas are not protected at the state level, "said Ian Burfield, scientific coordinator of the international organization"BirdLife International".

One of the solutions to this problem is the creation of special "biodiversity zones". This status will protect the unique habitats of species under threat of extinction.

"Status "area of biodiversity" provides many benefits to the local community and protect water resources and preserve the local biodiversity and reducing the negative impact of climate change", - the expert emphasizes on biodiversity, the UN environment programme Ersin Esen.

The conference of the parties to the Convention on biological diversity is being held in Sharm El-Sheikh from 17 to 29 November. The parties to the Convention assess progress in the implementation of the strategic plan on biodiversity for 2011-2020. The UN Convention on biological diversity, which protects natural resources, was developed at the world summit on environment and sustainable development in Rio de Janeiro in 1992. It has been ratified by 196 countries.
