  12. Objectives • To provide our audience with the understanding that fresh water, forests and the biodiversity they supply are already under considerable stress. • We wish to accomplish an educated understanding for our audience that as the human population grows greater stress will be applied to the earths natural resources. • The audience should know that as population increases resource deficits become larger populations can fail (crash).
