Robert Owen, pioneer socialist and co-operator (and ethical entrepreneur):
Nature requires its own time to mature all things, whether mineral, vegetable, animal or mind and spirit.
– topical as we zoom past the safe operating margins for life on this planet. It expresses three key rules of ecological economics:
2. Extract renewable resources like fish and timber at a rate no faster than they can be regenerated.
3. Consume non-renewable resources like fossil fuels and minerals at a rate no faster than they can be replaced by the discovery of renewable substitutes.
4. Deposit wastes in the environment at a rate no faster than they can be safely assimilated.
(number 1 is : Maintain the health of ecosystems and the life-support services they provide.)
and Owen again:-
The ever changing scenes of nature afford not only the most economical, but also the most innocent pleasures that man can enjoy.
– which recalls the buen vivir, or good living principles of the Andean indigenous movement.
