"To those who resist the notion that increasing food production also means increasing human population, consider this. In 1950, the global population stood at about 2.5 billion people. The Green Revolution was about to explode into global agriculture, substantially increasing crop yields on the back of profligate fossil fuel inputs (for fertilizer, mechanization, energy for irrigation, transport, processing, etc.). Let’s say this tsunami of energy and technology had not arrived on the agricultural scene, and that moreover a global edict (“magically” followed) held annual food production at the 1950 level thereafter. Would we have 8 billion people today? Impossible. We would still have 2.5 billion, correct? In 1950, the world produced enough food for 2.5 billion people, so that same amount of annual food would sustain 2.5 billion people today…or perhaps 2 billion taller, heavier people; or 3 billion people with more equitable, modest distribution and less waste. But you get the point: hold the food supply steady and you essentially hold the population below some cap. Inarguable. Those additional 5.5 billion people were made possible by a technological wave of food increase."
