The UN’s Food and Agriculture Organization estimates that the global meat production will double from 2000 to 2050. The reasons behind are two-fold:

  1. The world’s population growth is expected to settle around 9 billion in 2050.
  2. The global GDP is estimated to quadruple towards 2050.

It’s obvious that more people means more mouths to feed, but less obvious is the fact that meat demand grows with income: As peoples’ wealth increases so does their taste for meat. In fact, this economic growth is the main driver behind our 100% increase in meat consumption.

The trophic level of an organism is the position it occupies in the food chain: 1 is a plant, 2 is an animal that eats plants, 3 is an animal the eats animals that eats plants. The human trophic level (HTL) is 2.3, meaning 30% of our calories come from animals that eats plants. As income increases, so does HTL. PNAS
