...it is not just population that has bloomed. Since 1800, propelled by a 28-fold increase in primary energy use, mostly fossil fuel, real global GDP has increased over 100-fold. World average per capita income (consumption) is up by a factor of 13, rising to 25-fold in the richest countries. As famously observed, Earth is being asked to accept not only more people but ever larger people.
