Worldwide, 2 billion people live on a meat-based diet & 4 billion on a plant-based diet. The US food production system uses 50% of the total US land area, 80% of the fresh water, and 17% of the fossil energy used in the country.
To produce 1 kcal of plant protein requires an input of about 2.2 kcal of fossil energy.
For every 2.2 lbs of high-quality animal protein produced, livestock are fed 13 lbs of plant protein.
US livestock consumes more than 7 times as much grain as is consumed directly by Americans.
This is because a meat-based diet consumes 273 lbs of flesh & 45 lbs of fish/year which requires 9 BILLION animals to be raised and killed each year in the US alone.
Not only does a vegan diet leaves the smallest environmental footprint, while the US grows crops to feed animals, the World Health Organization reports over 3 billion people are malnourished. The amount of grains fed to US livestock is sufficient to feed about 840 million people who follow a plant-based diet.

Earth Sustainment & Food Shortages
The lactoovovegetarian diet is more sustainable than the average American meat-based diet according to an American Journal of Clinical Nutrition report
Loma Linda University study concludes vegans’ diet creates 41.7% less greenhouse gas & that plant food production is 11 times more efficient than animal foods
We need more food for humans instead of livestock Read more because study after study shows crop production must increase by 50-60% by 2050 to meet increase population, increased meat consumption and increased biofuel needs.
Our ability to supply the world with vegetables is practically unlimited,” Babcock said. But people would rather eat meat than feed the poor. NPR Marketplace
Study finds vegetarian diets required 2.9 times less water, 2.5 times less primary energy, 13 times less fertilizer, and 1.4 times less pesticides than non vegetarian diets.

Livestock cause 14.5% of greenhouse gas emissions; more than the global transport sector.
Study finds non-vegetarians experienced a 20 % higher mortality rate and had a diet that caused 29% more greenhouse gases than vegetarians.
UK study notes agriculture accounts for 14% of global emissions and finds vegans account for 2.89 kg of CO2/2,000 kcal consumed, vs 5.63 from medium or 7.19 kg from high meat eaters.

NY Times: Cargill deforests rainforest to grown soy for cows
Study of 34,000 California respondents found “the difference in water use for the vegetarian and nonvegetarian diet was 1000 L (264 gallons)/wk.” Those with a veg diet conserved an equivalent of 54% of the weekly per capita indoor water consumption.
The USGS.gov estimates (revised downward after pressure from animal agriculture).
Producing 1 kg of animal protein requires 100 times more water than producing 1 kg of grain protein.
Scientists estimates range from 2500-6000 gallons of water per pound of meat.
To produce 8 oz: soy milk-9 gallons of water; cow’s milk-30 gallons of water.
Meanwhile, corporations are buying up the world’s water (here).
Numbers of fish drop 50% since 1970.
This study shows it takes 2000L of water to produce 1 kilo of soybeans & 43,000L to produce 1 kilo of beef.
