the needs of the present without compromising the ability of future
generations to meet their own needs (1984, United Nations

including responsible use of resources (Oxford English Dictionary
Online) Natural Resources materials, and energy that occur
naturally within the Earths spheres. Many are essential for our
survival, while others are used for satisfying our wants.

STEWARDSHIP: the individuals responsibility to manage his life
and property with proper regard to the rights of others Websters
Ninth New Collegiate Dictionary (1987) Stewardship of Earth
Resources Responsible stewardship of mineral resources demands that
we make sensible and fair choices of where, how, and when to
acquire critical resources we need for today and for the future.
inconvenient truths Making these choices also requires that we face
some other inconvenient truths about the earth and our interaction
with it.
