Animal agriculture is the leading cause of species extinction, ocean dead zones, water pollution, and habitat destruction. [xix] [iv]
Animal agriculture contributes to species extinction in many ways. In addition to the monumental habitat destruction caused by clearing forests and converting land to grow feed crops and for animal grazing, predators and "competition" species are frequently targeted and hunted because of a perceived threat to livestock profits. The widespread use of pesticides, herbicides and chemical fertilizers used in the production of feed crops often interferes with the reproductive systems of animals and poison waterways. The overexploitation of wild species through commercial fishing, bushmeat trade as well as animal agriculture’s impact on climate change, all contribute to global depletion of species and resources.

A farm with 2,500 dairy cows produces the same amount of waste as a city of 411,000 people. [vi]

130 times more animal waste than human waste is produced in the US – 1.4 billion tons from the meat industry annually. 5 tons of animal waste is produced per person in the US. [xii]
"Animal Agriculture: Waste Management Practices". United States General Accounting Office. July 1999
In the U.S. livestock produce 116,000 lbs of waste per second:
-Dairy Cows, 120 lbs. of waste per day x 9.32 million dairy cows
-Cows, 63 lbs. of waste per day x 83.68 million cows
-Calves, 30 lbs. of waste per day x 34.3 million calves
-Pigs, 14 lbs. of waste per day x 74 million pigs
-Sheep and Goats, 5 lbs. of waste per day x 7.84 million sheep and goats
-Turkeys, .87 lbs. of waster per day x 77 million turkeys
-Broiler Chickens, .50 lbs. of waste per day x 1.74 billion broiler chickens
-Laying Hens, .25 lbs. of waster per day x 350.7 million laying hens
*pigs are raised twice per year, (a total of 148.3 million per year) so on any given day in the United States there are about 74 million pigs.
*turkeys are raised three times per year (a total of 233 million per year) so on any given day in the United States there are 77 million turkeys.
*broiler chickens are raised 5 times per year, (a total of 8.69 billion per year) so any given day there are1.74 billion broiler chickens.
Dairy Cows produce (120 lbs. x 9.32 m.) = 1.1184 billion lbs.
Cows produce (63 lbs. x 83.68 m.) = 5.27184 billion lbs.
Calves produce (30 lbs. x 34.3 m.) = 1.029 billion lbs.
Pigs produce (14 lbs. x 74.0 m.) = 1.036 billion lbs.
Sheep and Goats produce (5 lbs. x 7.84 m.) = 39.2 million lbs.
Turkeys produce (.87 lbs. x 77.0 m.) = 66.99 million lbs.
Broiler Chickens produce (.5 x 1.74 b.) = 870 million lbs.
Laying Hens produce (.25 x 350.7 m.) = 87.675 million lbs.
*Total manure produced in one day is 9.519105 billion lbs.
*Total manure produced in one year is 3.475 trillion lbs.

The US lower 48 states represents 1.9 billion acres. Of that 1.9 billion acres: 778 million acres of private land are used for livestock grazing (forest grazing, pasture grazing, and crop grazing), 345 million acres for feed crops, 230 million acres of public land are used for grazing livestock.

- WASTE -
Every minute, 7 million pounds of excrement are produced by animals raised for food in the US.
This doesn’t include the animals raised outside of USDA jurisdiction or in backyards, or the billions of fish raised in aquaculture settings in the US. [v]

A farm with 2,500 dairy cows produces the same amount of waste as a city of 411,000 people. [vi]
"Risk Assessment Evaluation for Concentrated Animal Feeding Operations".Environmental Protection Agency. 2004
130 times more animal waste than human waste is produced in the US – 1.4 billion tons from the meat industry annually. 5 tons of animal waste is produced per person in the US. [xii]
"Animal Agriculture: Waste Management Practices". United States General Accounting Office. July 1999
In the U.S. livestock produce 116,000 lbs of waste per second:
-Dairy Cows, 120 lbs. of waste per day x 9.32 million dairy cows
-Cows, 63 lbs. of waste per day x 83.68 million cows
-Calves, 30 lbs. of waste per day x 34.3 million calves
-Pigs, 14 lbs. of waste per day x 74 million pigs
-Sheep and Goats, 5 lbs. of waste per day x 7.84 million sheep and goats
-Turkeys, .87 lbs. of waster per day x 77 million turkeys
-Broiler Chickens, .50 lbs. of waste per day x 1.74 billion broiler chickens
-Laying Hens, .25 lbs. of waster per day x 350.7 million laying hens
*pigs are raised twice per year, (a total of 148.3 million per year) so on any given day in the United States there are about 74 million pigs.
*turkeys are raised three times per year (a total of 233 million per year) so on any given day in the United States there are 77 million turkeys.
*broiler chickens are raised 5 times per year, (a total of 8.69 billion per year) so any given day there are1.74 billion broiler chickens.
Dairy Cows produce (120 lbs. x 9.32 m.) = 1.1184 billion lbs.
Cows produce (63 lbs. x 83.68 m.) = 5.27184 billion lbs.
Calves produce (30 lbs. x 34.3 m.) = 1.029 billion lbs.
Pigs produce (14 lbs. x 74.0 m.) = 1.036 billion lbs.
Sheep and Goats produce (5 lbs. x 7.84 m.) = 39.2 million lbs.
Turkeys produce (.87 lbs. x 77.0 m.) = 66.99 million lbs.
Broiler Chickens produce (.5 x 1.74 b.) = 870 million lbs.
Laying Hens produce (.25 x 350.7 m.) = 87.675 million lbs.
*Total manure produced in one day is 9.519105 billion lbs.
*Total manure produced in one year is 3.475 trillion lbs.
