How does the American system of farming grain-fed livestock affect the world food supply?

What would happen if all the grain now fed to livestock were exported?

If all the U.S. grain now fed to livestock were exported and if cattlemen switched to grass-fed production systems , less beef would be available and animal protein in the average American diet would drop from 75 grams to 29 grams per day.

How much soil erosion does livestock cause?

Livestock are directly or indirectly responsible for much of the soil erosion in the United States, the ecologist determined. On lands where feed grain is produced, soil loss averages 13 tons per hectare per year. Pasture lands are eroding at a slower pace, at an average of 6 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.

Is there a potential to raise crop yields to feed a growing world population?

All in all, the potential to raise crop yields to feed a growing world population seems to be considerable, FAO said. “If the appropriate socio-economic incentives are in place, there are still ample ‘bridgeable’ gaps in yield (i.e. differences between agro-ecologically attainable and actual yields) that could be exploited. Fears that yields are reaching a plateau do not seem warranted, except in a very few special instances.”
