farms are causing deforestation and greenhouse gas
The United Nations for the first time show the transition to a diet free of animal products such as the way forward to resolve food and environmental problems facing the planet.
The unique position, which mirrors what many environmental and animal welfare groups say some time, when they stress the good Ragoni not only ethical, but also ecological, to switch to a vegan diet, read the latest report released by the ' Unap, the UN Environment Programme, published last June 2. The conclusions of the study entitled "Assessing the Environmental Impacts of Consumption and Production", scientists warn about the risks of perspective in which the increase in world population during the match increased consumption of meat, fish, milk and eggs, which would have devastating environmental consequences preventable with only a drastic change in eating habits throughout the world and the renunciation of the use, by all animal products.
According to projections published this year by the FAO, in fact, the current cultural model and the spread of established western lifestyle will bring meat production to more than double by 2050 (coming from the current 228 million tonnes to 463 million).
Without a reversal, it will be a real environmental disaster whose effects are calculable right now, given the unsustainability of the model that emerges from all the data highlighted in the reports of 'intergovernmental organization, without but never emerged from this knowledge are concrete policy initiatives. The UN report indicates
animal husbandry among the first voices of the priorities to be addressed in the near future, recognizing animal husbandry as a source of the primary causes of pollution and global warming, which causes environmental more damage than the production of building materials such as sand and cement and materials such as plastic and metal, and stresses that crops for animal feed are harmful as the consumption of fossil fuels. But
animal husbandry is, above all, one of the areas in which greater waste of resources. Strictly in terms of energy, in fact, as explained in detail the Niece (Nutricion Ecology International Center), the breeding of animals "farm" is one of the investments are less profitable and the animals are like "protein factories down" since the operation of their metabolism causes the capital invested in the production of meat is then returned in a dramatically lower. Suffice it to say that
need 25 kcal of corn to make one kcal of beef, 11 times more than the energy required for the production of wheat, which amounts to about 2.2 kcal. And the ratio is 57:1 for the lamb, for beef 40:1, 39:1 for eggs, 14:1 for milk and pork for the turkey 10:1, 4: 1 for the chicken.
And while the livestock sector consumes the calories that could feed the people of the South, is even worse with the water that wears away, because, in addition to 8% of drinking water worldwide is used for watering the animals directly inmates farms, is the enormous amount necessaria per coltivare i foraggi che li nutrono.
A conti fatti, per ottenere un chilo di manzo da allevamento intensivo si sprecano duecentomila litri d’acqua a fronte dei duemila che bastano, ad esempio, per la stessa quantità di soia dal valore nutritivo comparabile.
Se poi si pensa che allevare gli animali produce più emissioni di gas serra rispetto al settore dei trasporti e ben il 64% dell’ammoniaca totale, che concorre all’acidificazione degli ecosistemi e alle piogge acide, è chiaro come la zootecnia contribuisca anche a complicare gli sforzi per la conservazione della biodiversità. Secondo l’ultimo rapporto Fao il 10% delle specie protette rischiano l’estinzione per cause riconducibili direttamente gli allevamenti intensivi, perché il 26% delle terre libere dai ghiacchi è destinato all’allevamento e soggetto a deforestazione e erosione, mentre le deiezioni animali, prodotte in quantità che i terreni non sono in grado di smaltire, contaminano gravemente gli ecosistemi acquatici.
Cambiare le cose, però, stavolta, è alla portata di tutti. Negli ultimi paragrafi del rapporto Onu, nel capitolo sui consumi, gli scienziati indicano chiaramente la via da seguire, sottolineando quanto sia diretto il rapporto tra dieta e salvaguardia del pianeta e come scegliere i prodotti animali comporti un ben maggiore impatto rispetto ai prodotti vegetali. Poche volte come in questo caso la responsabilità di salvare il mondo passa in concreto by the daily choices.
