MONTREAL -- 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 be changing in the future.

Or, if those grains were exported, it would boost the U. With only grass-fed livestock, individual Americans would still get more than the recommended daily allowance RDA of meat and dairy protein, according to Pimentel's report, "Livestock Production: Energy Inputs and the Environment. An environmental analyst and longtime critic of waste and inefficiency in agricultural practices, Pimentel depicted grain-fed livestock farming as a costly and nonsustainable way to produce animal protein.

He distinguished grain-fed meat production from pasture-raised livestock, calling cattle-grazing a more reasonable use of marginal land. Animal protein production requires more than eight times as much fossil-fuel energy than production of plant protein while yielding animal protein that is only 1. Tracking food animal production from the feed trough to the dinner table, Pimentel found broiler chickens to be the most efficient use of fossil energy, and beef, the least.

Chicken meat production consumes energy in a ratio to protein output; beef cattle production requires an energy input to protein output ratio of Lamb meat production is nearly as inefficient at , according to the ecologist's analysis of U.
