". . . the precise water footprint of chocolate depends on the the origin of the cocoa and the methods of production but based on global average figures, a 100g [3.5 oz.] chocolate bar takes 1,700 litres [ca. 450 US liquid gallons] of water to produce."

How Much Food and Water is Wasted in the World?
The FAO World Food Clock
-- The Food and Agriculture Organization (FAO) of the United Nations
"How much food is being consumed around the world right now? It's a vast question that can be answered by the World Food Clock. This interesting website draws on information provided by the Food and Agricultural Organization (FAO) of the United Nations and presents a streaming set of data on global food consumption, global food waste, and other informative topics. It's visually arresting and users can scroll down to look through different "clocks" that track statistics such as the land used to grow wasted food and the stages of food waste, which include production, processing, and consumption. This is a wonderful tool for folks with an interest in food security, environmental studies, public health, and international relations. It could also be used in any number of design courses to illustrate a range of techniques and visualization strategies." KMG, The Scout Report
