The Green Planet — Season 1

Tropical rainforests are plant battlegrounds. New filming techniques allow us to enter the world of plants to see it from their perspective and on their timescale.

Water plants create beautiful, bizarre worlds. Flowers smother rivers and lakes. Plants fight and hunt. A river bubbles like champagne as plants create the atmosphere itself.

The strategy, deception and feats of engineering that plants use to thrive in the changing weather of different seasons. In the face of conditions ranging from ice and snow to raging fires, survival is often a question of perfect timing - particularly when contending with intense competition and surprising predators.

Desert plants spend decades in suspended animation waiting for rain, or they travel to find it. They survive using weapons, camouflage and surprising alliances with animals.

Two out of five wild plants are threatened with extinction. Today people are finding remarkable ways to help them, and so make our world a little greener and a little wilder.
