What two deveopments helped increase the food supply?

Two significant developments that helped increase the food supply are the Green Revolution and advancements in agricultural technology. The Green Revolution introduced high-yielding crop varieties, improved irrigation techniques, and the use of fertilizers and pesticides, which greatly enhanced crop production. Additionally, modern agricultural technologies, such as precision farming and genetically modified organisms (GMOs), have further optimized farming practices and increased efficiency, contributing to greater food availability.
