Fire is helpful for cooking food and keeping warm, but can also damage homes and forests, and hurt people. The presentation outlines the three main ways to put out a fire by removing fuel, heat, or oxygen. It concludes by noting fire allowed humans to have settled life, but can be dangerous if uncontrolled.
