Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO).
