Algunas cifras sobre la ganadería y sus impactos ambientales
- Gases de Efecto Invernadero y Calentamiento Global -
Goodland, R Anhang, J. “Livestock and Climate Change: What if the key actors in climate change were pigs, chickens and cows?”
250-500 liters per cow per day, x 1.5 billion cows globally is 99 - 198.1 billion gallons. Rough average of 150 billion gallons CH4 globally per day.

- Suelo y residuos-
-Dairy Cows, 120lbs of waste per day x 9 million cows.
-Cattle, 63lbs of waste per day, x 90 million cattle.
-Pigs, 14lbs. of waste per day, x 67 million pigs.
-Sheep/Goats. 5lbs of waste per day, x 9 million sheep/goats.
-Poultry, .25-1lbs of waste per day, x 9 billion birds.
Dairy cows and cattle-1.08 billion pounds per day (from 9 million dairy cows, 120 pounds waste per cow per day) + 5.67 billion pounds per day (90 million cattle, 63 pounds waste per one cattle per day) = 6.75 billion pounds per day wasteor 2.464 trillion pounds waste per year (manure+urine)
** 3.745 trillion pounds waste per year(this is the equivalent of over 7 million pounds of excrement per MINUTE produced by animals raised for food in the U.S. excluding those animals raised outside of USDA jurisdiction, backyards, and billions of fish raised in aquaculture settings in the U.S.)

La causa principal de deforestación y destruccción de las selvas tropicales son la ganadería y los cultivos de alimento para la misma.
