The history of livestock industry is the greatest source of corn demand, livestock industry is increasing with the growth of demand for meat products. In 2006, the economy of the sector began to change dramatically. Feed costs have more than doubled, and price fluctuations have increased dramatically. The main factor behind this change is the demand for corn for ethanol production. The price of feed rapidly increased, the price of the finished product could not catch up, and cattle products suffered the highest losses ever.
A virtuous circle was not born on the farm. The farm only makes cheap beef. Efficiency of today's industrial farm system has brought major economic disadvantages to family farms and meadows and is obliged to pursue a "lowest cost" production model rather than a "best practice" model. Due to economic scale and operational leverage on the scale of the farm, it is difficult for farmers to compete outside the system. Cow life is separate, farmers are usually limited to one stage of the life cycle, all animals finally enter the farm. Like most existing food systems, the farm system is unsustainable and far below our capabilities.
Increase in global meat consumption - the result of explosive growth of industrial farms. In addition to high consumption in northern industries, consumption of meat production and consumption in developing countries has doubled - mainly on food production farms, which consumed 7 pounds in exchange for small producers. Tonnage of meat per meat - 5% of the world's grain has been converted to agricultural fuel to raise grocery prices. The US Department of Agriculture claims that agricultural fuel is responsible for a 5 to 20% increase in food prices. International Food Policy Institute (IFPRI) has set it to 30%. According to a leaked World Bank report, this is 75%.
There is no doubt that the livestock system made a terrible mistake. Fairley expresses the US farm beef industry (animals are raised on pig farms) as "one of the rafts of the largest ecological system in modern history". It injects into the farm animal species that can not efficiently process food and feed from irrigated meadow and produces enough fat beef to produce hamburgers. Cows are excellent lawn converters, but the converters for concentrated feed are very bad. This feed can be used frequently to manufacture pork
