As a comparison, the water footprint of soybeans is 206 gallons; corn is 108 gallons.

Do crops use more water than livestock?

Per ton of product, animal products generally have a larger water footprint than crop products. The same is true when we look at the water footprint per calorie. The average water footprint per calorie for beef is twenty times larger than for cereals and starchy roots.

How does animal agriculture affect water?

Grazing animals and pasture production can negatively affect water quality through erosion and sediment transport into surface waters, through nutrients from urine and feces dropped by the animals and fertility practices associated with production of high-quality pasture, and through pathogens from the wastes.

What percentage of the world’s water is in a cow?

So to work out the percentage of water in the cow, we divide the volume of the world’s water by the volume of water in the cow and multiply by 100. The answer is about 0.00025 billionths of a per cent, or 0.0000000000025 per cent.
