The world shortage of energy and materials resources poses a continuing challenge to engineers, particularly automotive engineers, to evolve designs which stretch critical materials usage and eventually replace these with more plentiful ones. To carry out their mission, engineers must educate government officials, business leaders and the public-at-large on a global basis to the necessary compromises; and engineers must share new knowledge in this area with their colleagues in all nations if mankind - in generations to come - is to enjoy a comfortable standard of living.
