Broad spectrum revolution

The broad spectrum revolution is a big change that happened in the way that people got food. It happened a long time ago and changed the way people ate. People used to get their food from hunting animals and gathering plants from the environment, but during the broad spectrum revolution, people started to grow their own plants and raise their own animals for food. This made it easier for people to get enough to eat, and it also made it easier to trade with other people. This revolution helped people live better lives and grow bigger and stronger communities.
