L’Unione Internazionale per la Conservazione della Natura ha aggiornato la propria Lista Rossa delle specie minacciate, il leone è in pericolo, in ripresa la lince iberica.
Animals and plants have been going through extinction since ever, so it goes (would say Billy Pilgrim, protagonist of the novel Slaughterhouse-Five by Kurt Vonnegut). However, they are going extinct at an increasing pace, without an adequate regeneration.
Study published by Science Advances shows that vertebrates are going extinct at a pace 114 faster than expected. According to the International Union for Conservation of Nature (IUCN), 22,748 species are threatened with extinction.
The environmental organisation has updated its Red List, the largest database about the conservation status of animal and plant species. The IUCN highlighted the success reached thanks to conservation projects that led, for example, to the Iberian lynx (Lynx pardinus) population increase, in the past considered as the most endangered feline on the planet.
Unfortunately, good news gives way to bad news, showing significant drop in individuals of many animal and plant species. “Our natural world is becoming increasingly vulnerable,” warned IUCN chief Inger Andersen. “Effective conservation can yield outstanding results,” he concluded, referring to Iberian lynx protection plans.
The population of this elusive mammal passed from 52 individuals in 2002 to 156 at present. The species no longer qualifies for the Critically Endangered status and is therefore listed as Endangered. The improved status of this species is all due to intensive ongoing conservation actions, such as the rebound of rabbit populations, preys favoured by lynxes, and a programme of lynx individuals reared in captivity to be reintroduced in the wild.
Good news also comes for the Guadalupe fur seal (Arctocephalus townsendi), which was many times on the brink of extinction due to overhunting. At present, thanks to the implementation of laws, the population of these pinnipeds is thriving, moving from 200-500 individuals in 1950 to about 20,000 individuals in 2010.
However, other mammals are not that lucky, such as the Lion. The king of the forest remains overall listed as Vulnerable, with the western-African subpopulation listed as Critically Endandered, due to overhunting and preys decrease. The IUCN also highlighted the decline of the African golden cat (Caracal aurata), feline native to Central Africa, now listed as Vulnerable.
Whilst a species ponderously rebounds, thousands others get close to oblivion, always due to an only common denominator, called Homo sapiens.

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
The Lax Kw’alaams live not far from Canada’s border with Alaska, in the northern part of the province of British Columbia. The indigenous community has turned down an offer of $1 billion (Canadian dollars) and lands worth $108 million, i.e. $320,000 for each of the group’s members, for a liquefied natural gas (LNG) export hub
Laudato Si (Be Praised), On the Care of Our Common Home is the title of Pope Francis’ encyclical on the environment, the second one to be published during his papacy, after the Lumen Fidei on 29 June 2013.

Between 2011 and 2012 China has produced more cement than the United States throughout the 21st century. This is one of the most surprising figures of the report Vado a vivere in città: il boom dell’urbanizzazione in Cina (Going to live in cities: urbanisation boom in China), realised by Cecilia Attanasio Ghezzi and Nicola Longobardi for China
