The Eden Project in Cornwall, England, is an environmental complex designed to educate the public about the importance of plant life to our planet. It is built in a disused clay pit and is home to the world's biggest greenhouse.

The Humid Tropics Biome covers 1.6 hectares and houses tropical plants, a working stream and an impressive waterfall.

The Warm Temperate Biome is considerably smaller (0.7 hectares) and houses familiar warm temperate and arid plants such as olives and grape vines.

The Outdoor Biome represents the temperate regions of the world with plants such as tea, lavender, hops and hemp.
