Overconsumption and overpopulation underlie every environmental problem we face today

All life is part of a complex relationship in which each is dependent upon the others, taking from, giving to and living with all the rest.

No aquarium, no tank in a marine land, however spacious it may be, can begin to duplicate the conditions of the sea. And no dolphin who inhabits one of those aquariums or one of those marine lands can be considered normal.

Overconsumption and overpopulation underlie every environmental problem we face today.
