I've been hearing a lot about a "green" revolution. What's that about?

The green revolution is a term used to describe the agricultural advances in the 1960s and 1970s that led to an increased yield of crops, especially in developing countries. It was made possible by the use of synthetic fertilizers, pesticides, and improved seed varieties. This allowed farmers to produce more food for their families and communities, which helped to reduce poverty and hunger.
