In 2001, S. L. Davis of the Department of Animal Sciences at Oregon State University, Corvallis, wrote a paper claiming that the diet most likely to result in the deaths of the fewest animals would be beef, lamb, and dairy — not vegan. Davis found a study that measured mouse population density per hectare in grain fields both before and after harvest and estimated a harvest casualty rate of ten mice per hectare. Then, he multiplied that figure by 120 million hectares of farmland in the U.S.; meaning that 1.2 billion mice would die each year in food production if America became a wholly vegan country. Next, he estimated the number of animals that would be killed if half of our fields were dedicated to raising grass eating forage animals (cows, calves, sheep, lambs, etc.) from which to obtain meat. He found that there would Be 300,000 fewer animal deaths (.9 billion) annually from such an omnivorous diet than the number of deaths (1.2 billion mice) that would be caused from a universal vegan diet.

“… it appears that rice, when sown and
harvested mechanically, takes the greatest toll on higher
animals, especially amphibians. This is because rice
paddies can support large populations of animals in a
relatively small area.”

“[A] conservative annualized estimate of vertebrate deaths in organic rice farming is ~20 pound. … [T]his works out a bit less than two vertebrate deaths per square foot, and, again, is conservative. For conventionally grown rice, the gross body-count is at least several times that figure. … When cutting the rice, there is a (visual) green waterfall of frogs and anoles moving in front of the combine. Sometimes the “waterfall” is just a gentle trickle (± 10,000 frogs per acre) crossing the header, total for both cuttings, other times it is a deluge (+50,000 acre)."
