    Food should be produced at a local level People should eat real food, not processed food. Smarter ways of farming sustainably.

    Local does not equal sustainable Real is relative. At 9 B we may all be eating crickets and bio-protein.

Living in a Crowded World

Population growth is the most significant driver of the demand for food. As of July 2015, the world population stood at 7.3 billion and is estimated to grow to at least 9 billion by 2050. In the current ‘business as usual’ mode, feeding a population of 9 billion would mean a dramatic simultaneous increase in the need for food, energy and water in the next decades. 60% more food, 50% more energy and 40% more water by 2050.

Adapted from work by Prof. Nicholas Jordan, University of Minnesota (2015)

“During 2016, it is estimated that 83,000,000 people will be added to the world’s total population.”
