Over the past forty years the Living Planet Index (an indicator of the state of AUDIT OF DEVELOPMENT biodiversity) has fallen by 30% in northern countries and fallen by 60% in the tropics. During this time there has been a doubling of demands on natural systems. Assessing the capacity of the ecological system to continue to provide favorable conditions for civilization must be part of an audit of development. THE BALANCE SHEET FOR GROSS GLOBAL PROSPERITY Biodiversity has been fallen by a rate of 30% in northern countries and 60% in the tropical world over the past 40 years.
