The Green Planet

More kinds of plants are crammed together in the tropical rainforests than anywhere else on earth. The result is astonishing beauty and intense competition - a plant battleground. New filming techniques allow us to enter the plants' world and see it from their perspective and on their timescale.

Water plants create some of the most beautiful and bizarre spectacles in nature.

Plants use strategy, deception and engineering to thrive in this changeable world.

Desert plants thrive using weapons, camouflage and strange alliances with animals.

We rely on plants for almost everything, including the air we breathe and the food we eat. Two in five wild plants are threatened with extinction, but people are finding new ways to help them, from projects in Africa to reseed the landscape to the rebuilding of a tropical forest in Brazil, tree by tree.
