CAT: Centre for Alternatives Tecnology
The patron saint of Wales, St David, had an enormous respect for nature: the earth was the main source of food for his simple and healthy diet, and he taught his followers the importance of living in harmony with the environment that surrounded them.
In more modern times Gerard Morgan-Grenville founded the Center for Alternative Technology (CAT) in Machyllneth, Mid Wales, which over the years has become the central point of the Welsh environmental movement.
