"The gross national product does not allow for the health of our children, the quality of their education or the joy of their play."

"A true conservationist is a user, not a preservationist."

"The earth we abuse and the living things we kill will, in the end, take their revenge; for in exploiting their presence we are diminishing our future."

"We're not just after treasure. We're preserving history."

"The mind is humanity's greatest tool."

"A tidy room reflects a tidy mind."

"You can learn a lot about a person by how they keep their space."
