“The overall legacy we leave to our grandchildren is a combination of the side effects and leftovers of countless individual decisions – on purchases, policies and projects. How wisely those decisions are made determines whether that legacy contributes to sustainability or to further degradation.”

– Robert Gibson

“Sustainabilty is possible only if our activities maintain and repair the ongoing life-supporting functions of our environment, and only if we build social justice and mutual cooperation as well as technological capacity.”

– Robert Gibson
