"You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete."

Buckminster Fuller, philosopher, futurist and global thinker (1895 - 1983)

Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

The Report of the U.N. Brundtland Commission, Our Common Future, 1987

"If there are to be problems, may they come during my life-time so that I can resolve them and give my children the chance of a good life."

Kenyan proverb
