ABSTRACT
This chapter discusses learners new to the concept of sustainability need grounding in its definition and the underlying scientific principles. Teaching the science, even to non-scientists, is not that difficult. Overcoming misconceptions, prejudice, disinformation and guilt are the real challenges. Alternatives to 'sustainability' include Zero waste, Green building, Green chemistry, Community health, Social responsibility, Triple bottom line, Resource efficiency, Product certification and Enlarged definition of quality. Organisations often confuse sustainability with other 'green' or environmental programmes. Organisations at this level are primarily concerned with avoiding legal liabilities and may view environmental issues as a source of additional costs and headaches. Organisations focusing on eco-efficiencies have discovered that saving resources not only helps the environment but also their financial bottom line. One of the biggest psychological barriers is despair and helplessness. Many people feel guilty about their lifestyles and choices; they know about the environmental problems.
