"America's billions of factory farmed animals produce a staggering quantity of excrement: about 89,000 pounds per second."
"And unlike municipal sewage, the animal waste from factory farms is not treated, so all the potentially lethal pathogens such as E. coli, Cryptospordium, and Salmonella remain intact."
"In the United States, untreated animal waste in the forms of feces, urine, vomit, and other effluvia, have polluted the ground-water in seventeen states."

"Untreated chicken and hog waste from factory farms in Maryland and North Carolina is believed to have contributed to outbreaks of Pfiesteria piscicida, which killed millions of fish and caused skin irritation, short-term memory loss, and other cognitive problems in local residents."
"And in 2011, a hog farm in Illinois spilled 200,000 gallons of untreated pig waste into a creek, killing over 110,000 fish."
"Animal agriculture not only pollutes water on an enormous scale, but also uses tremendous quantities of this incredibly precious natural resource, accounting for one half of all the fresh water used on the planet."

"In the United States alone, over 260 million acres of forest, an area larger than Texas and Colorado combined, have been clear-cut and converted into cropland for cattle."
"In the Amazon, rainforests are being clear-cut at a rate of over forty-seven acres a minute to create pastures for cattle."
"According to the Union of Concerned Scientists, cattle pastures make up 70 percent of the world's agricultural land, but yield only 6 to 11 percent of our food."
"For every person who goes vegan, one acre of trees is spared every year."
"One acre is equal to three-quarters of a football field, or about seven-hundred trees."
