The planet Earth holds over seven billion humans. Somehow, against all manner of predictions to the contrary, we feed all of them. This would have astounded Thomas Malthus who, in 1798, predicted that humanity was careening toward a demographic catastrophe, despite the world population still being under a billion at that time.
Part of the reason why humanity can now feed itself is because of agricultural advances in the 20th century known as the Green Revolution. Advances in crop yields, land use, pesticides, herbicides, and general efficiency have given us a food supply unlike anything that our ancestors knew. At the forefront of the Green Revolution was a biologist named Norman Borlaug who developed a type of semi-dwarf wheat that saved an estimated billion lives.
