The supermarket - the modern land of milk and honey! Located just around the corner, it provides us with a magnificent selection of food and beverages: fresh fruits and vegetables from all over the world, meat and fish in abundance, coffee from Brazil, rice from Thailand, beef from Argentina – every product available 24/7. For most inhabitants of the industrialized world, purchasing and consuming food is easy and convenient. No dirty hands, only a few dirty dishes. Food consumption has become so easy and cheap that it is done on an excessive level: since 1980, the number of obesity cases has doubled globally and reached more than 1.4 billion adults in 2008 according to the World Health Organization Fact sheet No. 311 (2012).
