Question

Why does eating less meat conserve more water than just eating plants?

Answer 1

You turn off the faucet when you’re brushing your teeth and you definitely don’t take twenty-minute long showers. While these acts, along with the use of appliances that save water like toilets and showerheads, are fantastic ways to conserve water … if you really want to make a difference with water conservation, then there is a bigger piece of the puzzle to consider.
Every food and beverage product we consume: from soda to pineapples to cheese crackers and pork chops, etc. requires water for its production. Obviously, fruits and veggies need water. That’s a given, but surprisingly, there is another group of foods that is the biggest water guzzler of them all and that is animal products. Meat, dairy, and eggs require more water to “produce” than any other food out there.

Answer 2

Answer:

Studies show that eating fewer animal-based products could reduce water use since animal production uses more water than crops do. In addition, reducing the amount of food that's lost or wasted at various points in the food supply chain could feed about 1 billion extra people while simultaneously reducing water use.
