The concept of sustainable development implies limits to growth – those imposed on environmental resources by the present state of technology and the effects of human activities on those resources.  Currently, pollution of the atmosphere, destruction of forests, soil erosion, mineral extraction, watercourse diversions and agricultural practices and are all examples of human impacts on natural systems during the course of development.  These interventions were previously limited in impact but now occur in large-scale projects leading to more drastic environmental effects.

Sustainability does not imply reducing our standard of living.  However, if we are to practice stewardship of the environment, the right choices have to be made in our approach to living responsibly.  This challenge must be accepted if we intend to leave the world a better place for future generations.

The paradigm shift required in our thinking must incorporate alternative sources of energy as a standard approach to cost effective planning and design.  The use of solar and wind power are natural considerations in the Caribbean.  Solar water heating of homes is well advanced technology established over the past 30 years and in 2007, the fully powered solar prototype home was exhibited in Barbados.  Conservation and recycling of water is also cost effective and should be implemented through rainwater storage tanks, water treatment and reuse through automatic irrigation systems to help reduce monthly demand. Energy saving devices should also be used in buildings particularly in tourism driven economies where wastage and high consumption practices exist.  Needless to say, ongoing public education programmes will be a necessary aspect of these initiatives.
