"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."

"Imagination is more powerful than knowledge."

"The world is full of wonders if you know where to look."

"You have the imagination of a child, Lucy"

"The world is full of mysteries waiting to be solved."
