We have the climatic change until in the soup. But the consumption of meat and the way in which we fed the 6,400 million human beings who we inhabited the planet affects to the air which we breathed, besides knowing a clearly social impact. As the man is done of the nature surrounds that it, it interacts with her, it uses as her to feed itself and comprises of that nature of active way, we will tie the social thing to the environmental thing. A group of scientists and experts managed the past year to sensitize to million people on the destruction of the planet by a model of consumption based on hydrocarbons. But the improvement in the nutritional habits, is pending. One of those improvements consists of consuming less meat. In almost half century, the human consumption of meat in the world has been quadrupled. The individual consumption of meat has been duplicated in that same period of time, with the forecast for 2050 of which that consumption becomes to duplicate.
Although the world-wide consumption of meat is not equitable, the averages are over which the Earth can hold. Almost a third of the free land surface of ice of our planet it is dedicated or somehow related to the cattle, generating production of 18% of greenhouse effect gases. Another 13% come from the transport and another 19.4% of industrial activities, according to the Intergovernmental Panel for the Climatic Change of the United Nations. The cattle ranch uses a third of world-wide the agricultural land to produce animal food, a process related to the deforestation of tropical forests, mainly in Latin America, where the cattle operation has grown in a 4% in the last years, when the world-wide average is below 2%. Brazil and Argentina replace the demand of cereals to feed the cattle of the Asian east that, due to the small territorial extension and to the cultivable earth shortage, they must concern them.
