A vegan who uses B100 made from soybeans usurps 5 times more land for his or her car than their beef eating counter parts feed to their cows.
1 hectare = 2.47 acre
1kg = 2.2 lbs.
[200 kg beef / hec] x [hec/2.47 acre] x [2.2lbs / kg] = 1068 178lbs beef /acre for cattle in Brazil. See note 3.
It takes about 24 months for Brazilian beef to get to market
One soy crop is grown per 12 months
About 0.55 percent of a Brazilian cow becomes beef. See note 2.
[178lbs beef /acre] x [12 months / 24 months] x 0.55 = 293.7 48.99lbs dressed beef /acre
[70lbs beef] / [293.7lbs beef / acre] = 1.43 acres dedicated per American to feed them their 70lbs of beef. See note 1.
Biodiesel = 9.12 acres per year.
Beef = 1.43 acres per year
Anyone who uses B100 made from soybeans usurps 9.12/1.43 = 6.38 times as much land as the average American who eats beef.
Notes:
Note 1: http://www.findarticles.com/p/articles/mi_m3284/is_n2_v12/ai_7778163
Americans eat 70lbs of beef/year down from 94lbs at its peak.
Note 2: http://beef-mag.com/mag/beef_touring_brazil/
The past few years, U.S. imports from Brazil, which aren't subject to quota restrictions, routinely have accounted for 4-5% of U.S. beef imports, or 0.35% of total U.S. supplies 20-30 months. Carcasses yield an average of 50-55% compared to about 65% in America.
Note 3: http://www.newint.org/issue184/fast.htm
"When the same hectare has been felled, torched, razed and seeded with grass for grazing, it will produce at most 200 kilograms of meat a year."
