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

"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

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