Chocolate lovers beware - its production requires over 17000 liters of freshwater per kilogram!

Global warming and quickly growing water use for human life and activity needs are the major risks leading to depletion of Earth's freshwater resources. Only 8% of water is used for domestic needs, while 70% - for irrigation, and 22% - for industry.
The daily drinking water requirement per person is 2-4 litres, but it takes 2000 to 5000 litres of water to produce one person's daily food. Production of chocolate (17000 liters/kg), beef (15000 liters/kg),cheese (3200 liters/kg) and bread (1600 liters/kg) are among most water intensive food production processes  (see image above).
Over one third of world's population currently do not have access to clean drinking water.
Ice and permanent snow cover in mountains, Antarctic and Arctic represent 70 percent of global freshwater.
