Project TARA

I mari con il loro contenuto di plancton e altri micro organismi responsabili di una consistente e continua attività fotosintetica producono la metà dell' ossigeno che respiriamo. In altre parole, una molecola su due di questo prezioso elemento proviene dagli oceani che, insieme alle foreste, costituiscono i polmoni del pianeta.
Basterebbe questo per capire l’importanza di preservare la salute di questi delicate ecosystems.
Knowing the state of the seas is the purpose of international scientific project TARA, an expedition around the world that will last three years, to collect data and assess the current state of the seas.
The choice of boat for patrolling the seas of the world went on a vessel of 35 meters and not on a large research vessel, bulky, polluting and too expensive. It 'was then created a network of collaboration with the scientific and local researchers actively involved in development work and data collection. Gimmick that allows organizations to comply with and involve other countries and to travel on board with only a few sophisticated equipment not available in all laboratories.

The extraordinary thing is that

10 READING GREEN RECOMMENDED

"The Deserted Village " by Oliver Goldsmith talks about a protest by workers in the agro-food sector of Georgia against the capitalists who want to steal his land.

"The Natural History and Antiquities of Selborne" one of the pioneers of naturalism, the Englishman Gilbert White, who tells the story of plants and animals observed in literary form by the zoologist Thomas Pennant lawyer Daines Barrington.

"The Prelude" by William Wordsworth , a story about wild landscapes spiritually uplifting, as I recall the author's childhood in the Lake District. One of the earliest visions of the beautiful nature.

"The Mores" John Clare, a collection of poems of Clare farmer, a hymn to the flora and fauna English. It is a kind of lament for the effects of enclosure, reminiscent of a "limited" campaign in an ideal of "green forever." The pleasure comes from nature, the maximum for an environmentalist, I must say.

“L’ultimo dei Mohicani” di James Fenimore Cooper. Uno dei più famosi film di Hollywood, è in realtà un romanzo che fa conoscere le antiche popolazioni d’America che vivevano immerse nella natura, sfidando le innovazioni dell’uomo bianco.

“This compost” di Walt Whitman. Una raccolta di poesie in cui l’autore è rapito dalla contemplazione del mistero con cui gli esseri umani e gli animali vanno in putrefazione, dando la vita al suolo. Un rinnovarsi continuo di uomo e natura che insieme formano un circolo perfetto.

“Binsey Poplars” di Gerard Manley Hopkins. Hopkins è il primo eco-cristiano della storia, visto che ha ammesso di aver visto “la grandezza di Dio nel mondo naturale”. Questa poesia esprime il suo dolore al taglio di alcuni pioppi vicino ad Oxford. Una sofferenza alleviata solo dalla consapevolezza che questi pioppi sono stati abbattuti solo per essere ripiantati. Oggi sono ancora lì.

“Walden, ovvero la vita nei boschi” di Henry David Thoreau. Due anni di permanenza in una capanna di Walden Pond vicino a Concord descrive un esperimento nel tentativo di seguire una vita semplice in sintonia con la natura.

“Una boccata d’aria” di George Orwell. Un romanzo basato sui suoi ricordi della crescita nella valle del Tamigi, in cui scopre con horror that, after several years, gradually everything was ruined, with construction on the fields and woods, and the pond in which he used to fish, become a landfill.

"Oryx and Crake" by Margaret Atwood . The most recent novel, which describes the world after a disaster due to genetic engineering in harmony with global warming. Our dreams for progress will produce the apocalypse, according to Atwood. Hopefully it does not, but these readings will show you the world a little 'greener.

THE DISAPPEARANCE OF PREDATORS

The catastrophic decline around the world at the top of the food chain predators such as wolves, cougars, lions or sharks, has led to a huge increase in smaller "mesopredatori" that are causing serious economic and ecological disruption. The study results were published in the journal Bioscience, and observe that in all North America's largest terrestrial predators are declining over the last 200 years, and have increased by 60% mesopredatori. The problem is overall, but some solutions are in sight.
For example, in some parts of Sub-Saharan Africa, populations of lions and leopards have been decimated, allowing an increase of baboons. In some cases, indigenous peoples today are forced to remain barricaded in the house when raids are made of baboons in their plantations.
The issue is very complex, and a lot of consequences are not known, but there is no evidence that the explosion of populations mesopredatorie is very serious and has an impact both environmentally and economically
said William Ripple, a professor of forest ecosystems and society at Oregon State University. In case after case, all over the world, are the primary predators been drastically reduced if not eliminated, due to disruption of habitat, hunting or fishing. Many times this was seen positively by humans for fear of a personal attack, the loss of livestock or other concerns. But the new image that emerges is a series of problems including damage to the ecosystem, which can present the new predators more difficult to fight.
For example, the elimination of wolves is often favored by farmers who fear the attacks on their livestock. However, this has led to huge increases in the number of coyotes, a mesopredatore once kept in check by wolves. Even the Pronghorn antelope coyote attacks gli ovini domestici, ma cercare di tenerli sotto controllo è estremamente costoso, molto più che controllare i lupi.
