One of the exercises that engage sociologists and opinion concerns the possibility in the future to feed the inhabitants of the Earth, now little more than seven billion, a slow but steady growth at least in the coming decades; a world population boston food trucks is expected to reach nine billion people in 2050. The tireless Lester Brown, president of the Institute for American policy of the Earth, a kind of ecological controller of the world, has recently published a new book, translated into Italian by Edizioni Ambiente which is entitled: "Nine billion seats at the table."
A crowd of diners that can be divided, in terms of food consumption, in about two billion people whose needs are met, sometimes with an excess of foods that cause obesity and diseases and lead to waste. boston food trucks About four billion people who live in countries of rapid industrialization, such as China, boston food trucks India, Brazil and others, with increasing food consumption; in some cases up to the level of those of more advanced countries, boston food trucks even if they survive in vast areas of poverty and malnutrition. Finally on Earth is about one billion people who provided food in quantities just sufficient or insufficient for survival.
These are figures that are repeated in the frequent complaints of the scandal of this situation and the need to cater to feed the poor. The scandal boston food trucks is also in the fact that the food resources offered by nature are often used badly or very badly. The food we put on the table comes to us after a long journey that begins in the fields and includes boston food trucks the complex operations of soil preparation, distribution of seeds and fertilizers, irrigation, boston food trucks the patient waiting for the plants to grow surpassing floods or drought or wind , the attack of pests and other adversities. The chain continues with the collection of food, transport via railways, trucks, ships from agricultural areas to the numerous industrial processes of preservation and processing with the use of chemicals, metals and plastics for packaging and transport to distribution.
A portion of the collected plant is used for feeding cattle, pigs, poultry; only a part, often only one tenth, boston food trucks of plant nutrients is transformed into nutrients for human nutrition; the rest ends up in excrement polluting gases of animal metabolism, in waste and waste. The animals and their products travel up to slaughterhouses and industries that store and process, again with losses and waste and pollution, and finally arrive in stores and on our table as meat, eggs, milk, foods with proteins finest. In all this there is a hidden but important component: energy.
The studies coincide in every calorie of food human entailed the use of seven calories of energy boston food trucks in agriculture, industry, animal husbandry, transport, distribution, household refrigerators and cooking. If you think that the useful energy for a person amounts to about a million kilocalories per year and that this energy corresponds to the energy content of one hundred pounds boston food trucks of oil, we see that the food consumed by sixty million inhabitants of Italy has resulted in a use of energy boston food trucks equivalent to that of 40 million tons of oil, equal to about a third of the energy used in Italy. The energy required to get the food on our tables has been used partly in Italian and partly in distant countries from which we import food.
On a global scale we can calculate that, for the production of food is used about one-fifth of world consumption of energy, resulting in air pollution, especially of gases responsible for climate change. Climate change, for their part, make it more expensive, such as money, such as consumption of energy and water and how pollution, food production, a situation likely to grow, and as they will increase the demand for food from the population poorest of the planet. A vicious boston food trucks spiral. And 'possible to feed a little' better the hungry only through an increased use of reserves, limited, both fossil fuel is water, and through a growing pollution of water, air and soil.
One solution could be represented by a new enhancement of agricultural and agro-industrial, not so much dreaming home gardens, or restaurants in kilometers-zero, or with food fads, but with better technical-scientific knowledge of the whole movement of nature, materials and work from the fields, industries, consumer. The only way to ascertain where and how you can limit energy waste water, food, decrease pollution and mitigate deterioration
