Plants are important to us. We use them for wearing, writing and reading.
Plants cure our sicknesses, provide us with food and shelter and give us energy. What would we ever do without plants!
Land plants have been around for about 400 million years, long before dinosaurs ruled the earth. After they died, they were buried by layers of dirt and rock. When the pressure and heat within the earth's crust was just right, many of the plants turned into coal! Coal is a fossil fuel that is used to make electricity.
