Abstract
M.A.
Sustainability has become a household word in development. Economic benefits
however, overshadow the restraints sustainability places over development (Van Riet,
1989). To take action on unsustainable development, a country should have some sort
of measurement tool to determine the condition or progress of unsustainable
development. To determine the impact South Africans have on the ecology has been
studied intensively but the actual measurements of these impacts have been neglected.
This study proposes a practical tool to measure the effect of human impact on the
environment.
