Zielona planeta

A journey into the magical world of the tropical rain forest, from fast-growing trees to flowers that mimic dead animals. New filming techniques allow us to enter the plants' world and see it from their perspective.

Water plants create some of the most beautiful, bizarre and important habitats on earth. To hold on in torrents, plants use a kind of super glue. While some are armed with vicious weapons to fight titanic battles for space.

Between the tropics and the frozen poles lies a region dominated by relentless change. To survive here plants must use strategy, deception and remarkable feats of engineering. Most importantly, they must get their timing right.

Deserts are hostile, temperatures soar and water is rare. Yet plants find extraordinary ways to survive. Plants have invaded the most dangerous deserts on earth to bring life and colour to these harsh landscapes.

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 rebuilding the forests in Brazil.
