March 22nd is World water Day. 

This is a good time to reflect on the fact that this life-sustaining resource is, unfortunately, not infinite.

Switching to a more plant based diet will significantly reduce the amount of water you consume indirectly.

The water footprint of foodstuffs varies enormously, depending on location, weather conditions, soils, species and production techniques.

Researchers have nevertheless been able to evaluate the amount of water required to produce one kilo of various foods. The illustration below shows that beef, for example, requires a lot of water.
