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).
