Beef Cattle Production Requires an Energy Input to Protein Output Ratio of 54:1

The thought of this commodity is to bring awareness most the benefits of beingness vegan and non making comments on choices as it is a fundamental right of everyone what to eat and what non.

From one ecologist's perspective, the American system of farming grain-fed livestock consumes resources far out of proportion to the yield, accelerates soil erosion, affects world food supply and will exist irresolute in the future.

Animate being protein production requires more than eight times equally much fossil-fuel energy than production of plant protein while yielding animal protein that is only ane.iv times more than nutritious for humans than the comparable corporeality of plant protein, according to the Cornell ecologist's assay.

If we runway food animal product from the feed trough to the dinner table,broiler chickens to exist the nearly efficient use of fossil energy, and beefiness, the least within the animal based food. Chicken meat production consumes energy in a four:1 ratio to protein output; beef cattle product requires an free energy input to protein output ratio of 54:1. (Lamb meat production is nearly as inefficient at 50:1, according to the ecologist'south analysis of U.S. Department of Agriculture statistics. Other ratios range from xiii:1 for turkey meat and 14:1 for milk protein to 17:one for pork and 26:1 for eggs.)

Animal agriculture is a leading consumer of water resources in the Us .Grain-fed beefiness production takes 100,000 liters of water for every kilogram of food. Raising broiler chickens takes iii,500 liters of h2o to make a kilogram of meat. In comparing, soybean product uses two,000 liters for kilogram of food produced; rice, 1,912; wheat, 900; and potatoes, 500 liters. Water shortages already are severe in the Western and Southern United States and the situation is quickly condign worse because of a rapidly growing U.S. population that requires more water for all of its needs, especially agriculture.

Livestock are straight or indirectly responsible for much of the soil erosion in the U.s.a., the ecologist determined. On lands where feed grain is produced, soil loss averages thirteen tons per hectare per year. Pasture lands are eroding at a slower pace, at an average of half dozen tons per hectare per year. But erosion may exceed 100 tons on severely overgrazed pastures, and 54 percent of U.S. pasture land is being overgrazed.

"More than half the U.S. grain and nearly 40 percent of world grain is beingness fed to livestock rather than being consumed directly by humans

EIGHT Compact FACTS Most Animate being Nutrient

From "Livestock Production: Energy Inputs and the Surroundings"

By David Pimentel

-- WHERE'S THE GRAIN? The 7 billion livestock animals in the Us consume five times as much grain as is consumed directly past the entire American population.

-- HERBIVORES ON THE HOOF. Each year an estimated 41 meg tons of plant protein is fed to U.S. livestock to produce an estimated vii million tons of animal protein for human consumption. Almost 26 one thousand thousand tons of the livestock feed comes from grains and fifteen million tons from forage crops. For every kilogram of high-quality animal protein produced, livestock are fed nearly 6 kg of found poly peptide.

-- FOSSIL FUEL TO Food FUEL. On boilerplate, animal protein production in the U.S. requires 28 kilocalories (kcal) for every kcal of protein produced for human consumption. Beef and lamb are the near plush, in terms of fossil fuel free energy input to protein output at 54:1 and l:1, respectively. Turkey and chicken meat production are the nearly efficient (thirteen:ane and iv:1, respectively). Grain product, on average, requires 3.3 kcal of fossil fuel for every kcal of protein produced. The U.S. now imports about 54 percentage of its oil; by the year 2015, that import figure is expected to rising to 100 percent.

-- THIRSTY Production SYSTEMS. U.Due south. agriculture accounts for 87 percent of all the fresh h2o consumed each year. Livestock straight use simply 1.3 per centum of that water. Just when the water required for forage and grain production is included, livestock's h2o usage rises dramatically. Every kilogram of beef produced takes 100,000 liters of water. Some 900 liters of h2o become into producing a kilogram of wheat. Potatoes are even less "thirsty," at 500 liters per kilogram.

-- HOME ON THE RANGE. More than 302 one thousand thousand hectares of land are devoted to producing feed for the U.Southward. livestock population -- about 272 million hectares in pasture and about thirty one thousand thousand hectares for cultivated feed grains.

-- DISAPPEARING SOIL. Virtually 90 percentage of U.S. cropland is losing soil -- to air current and water erosion -- at 13 times above the sustainable charge per unit. Soil loss is most astringent in some of the richest farming areas; Iowa loses topsoil at thirty times the rate of soil germination. Iowa has lost half its topsoil in only 150 years of farming -- soil that took thousands of years to class.

-- Enough OF PROTEIN: Nearly seven million tons (metric) of animal poly peptide is produced annually in the U.S. -- enough to supply every American man, adult female and child with 75 grams of beast protein a twenty-four hours. With the addition of 34 grams of available found protein, a total of 109 grams of poly peptide is available per capita. The RDA (recommended daily allowance) per adult per 24-hour interval is 56 grams of protein for a mixed nutrition.

-- OUT TO PASTURE. If all the U.South. grain at present fed to livestock were exported and if cattlemen switched to grass-fed production systems, less beef would be bachelor and animal protein in the average American diet would drop from 75 grams to 29 grams per twenty-four hour period. That, plus current levels of plant-protein consumption, would still yield more than than the RDA for protein.
