Falmouth, England, May 7, 2009--Clambering inside the Eden Project's tropical "biodome," rope-access technician Robin Teagle prepares to trim an errant balsa tree.

The tree, grown from seed ten years ago, had outgrown the biodome and was threatening its roof.

The Eden Project, a pair of domes housing a hundred thousand plants of all shapes, sizes, and origins, opened to the public in 2001.
