ABSTRACT

The diversity of (and interrelationships among) plants, animals and other organisms form the basis of the “web of life” and the biogeochemical processes that circulate matter and energy throughout the biosphere. The “ecosystem services” provided by nature include atmospheric and hydrological regulation, clean water, soil formation, erosion control, food, timber, biological control, genetic resources, waste sinks and a range of social, cultural and aesthetic values. The value of these ecosystem services to humanity in 1997 was estimated to be in the range of US$16-54 trillion per year (Costanza & Arge et al. 1997).
