The camp near Trier is made up of some 10 cabins and shacks that are centred around a large three-story tree house mounted on stilts. Photos: Harald Tittel/dpa

Meier heads for a tree house, 10m above ground. It's bed time. The young man straps himself into his harness, then feels his way along a rope to his spot.

The tree house is a great place to sleep, says Meier, 20, as it has a good view across the whole of the activists' camp below.
