Trees are the oldest, biggest, and most successful creatures in the world. Using energy from the sun, and carbon from the air, they have thrived on land for more than four hundred million years. Hear about the amazing and unique methods that plants around us use to establish, grow, flourish, and defend themselves. Learn how plants are much more than food, medicine, and wood — they form the living, striving foundation of Planet Earth.
