But not all of this water is accessible because part of it flows into remote rivers during seasonal floods. Animal agriculture is responsible for up to one third of all fresh water consumption in the world today.
Other researchers have much lower estimates such as 8 reviewed by Girard 2012. Livestock water use is water associated with livestock watering feedlots dairy operations and other on-farm needs. In addition plants arent slaughtered a process that demands 132 gallons of water per animal carcass.
