Bioenergy: fine, if from side streams
Why cannot we lift all barriers for the use of bioenergy? Because the energy sector is much larger than the food sector. The 20 billion tons of fossil fuels that mankind uses each year, is equivalent to 40 billion tons of biomass; whereas our yearly harvest for food is 9 billion tons, of which 3

Can we engineer life? 4.1 Hunger in the world increases
In September 2017, the FAO released a report on hunger in the world. According to this report, in 2016 11% of the global population experienced hunger, i.e. 815 million people, 38 million more than in the preceding year.
