Check out how much water is needed to produce your food

Should I stop eating meat? No need, experts say

World Water Day celebrates its 19th edition March 22 and will be themed around water and food security.

At a time when drought, food and water scarcity are devastating parts of the world -- particularly the developing areas -- water advocates are pushing the notion of measuring your water footprint.

Aside from the water used for drinking, cooking, and washing, a major part of a consumer's water footprint also involves the virtual or embedded water needed to produce a product.

For example, it takes about 1,500 liters of water to produce 1 kg of wheat, and about 10 times more to produce 1 kg of beef. That translates to 7,000 liters of water for steak dinner.
