Lo sostiene un nuovo studio secondo il quale i governi mondiali non riescono a fornire la necessaria protezione alla natura.
In 2010, world’s governments committed to protecting and preserving 17% of land and 10% of sea by 2020, particularly those places considered essential for nature.
Today, 5 years before the deadline, new research carried out by 40 authors from 26 institutions, including the IUCN and BirdLife International, shows that the current protected areas system is failing to safeguard all key sites, endangered species, and threatened ecosystems.
“We carried out the most comprehensive analysis to date of how well Protected Areas cover nature,” said Dr Stuart Butchart, BirdLife International’s Head of Science and lead author of the paper. “We analysed nearly 12,000 important sites, over 1,000 terrestrial and marine ecological regions and over 25,000 species of animals and plants, including the first assessment for marine species”.
The analysis also revealed that only one-fifth of key sites for biodiversity are completely covered by protected areas, with one third lacking any protection. Furthermore, less than half of mammals, amphibians, mangroves and various marine groups have a sufficient proportion of their distributions covered by the current protected area network to be adequately conserved.
According to researchers, achieving adequate coverage of nature to meet globally adopted targets would require twice the area of protected sites in the world.
“Challengingly, the largest increases in land needing to be set aside for conservation are located in poorer countries of the world,” said Dr Neil Burgess of the UNEP and study’s co-author.
This research should be the wake-up call for governments and conservationists all over the world. The objective still remains far and achieving it requires recognition and designation of new protected areas, in order to adequately safeguard the beautiful nature surrounding us.

After more than 5 years from the environmental disaster of the Deepwater Horizon oil platform, on 20 April 2010, Gulf of Mexico, the British Petroleum (BP) agreed to pay a penalty of 18.7 billion dollars in order to end once for all the legal action the United States and other federal states took after the worst
Il Paese africano ha bruciato oltre una tonnellata di zanne e corni confiscati per esprimere la tolleranza zero per il bracconaggio.
He has already invested 1 billion dollars in tens of projects and innovative realities for the development of renewables all over the world. Maybe not all investments had the success and outcomes desired, but they have certainly been money well spent, since they set a guideline within the energy industry. With this in mind, the world’s richest man,
Una nuova ricerca ha dimostrato che il contatto con la natura inibisce la formazione di pensieri negativi che possono sfociare in gravi patologie come la depressione.
People are increasingly committing themselves to protect one of the Planet’s most important pollinators: bees. And in Norway they are creating a green corridor exactly for them.
100,000 lives were lost in the Sahel region of Africa between 1972 and 1984 due to a long lasting drought and the famine it caused. A recent scientific study shows that global warming has more recently increased rainfall in the area, temporarily relieving it from drought. This has led many, such as Forbes contributor James
