"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

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

"Then I say the Earth belongs to each generation during its course, fully and in its right no generation can contract debts greater than may be paid during the course of its existence"

Thomas Jefferson, September 6, 1789
