The risks of treating economic management and environmental quality as if they are separate, non-interacting elements have now become apparent. The world cannot continue to deplete the stratospheric ozone layer by indiscriminate use of chlorofluorocarbons (CFCs). Furthermore, damage to the ozone layer affects human health and economic productivity. Few would argue now that we can perpetually postpone taking action to contain the emission of greenhouse gases (GHGs). Our use of fossil fuels is driven by the goals of economic change and that process will affect global climate. In turn, global warming and sea-level rise will affect the performance of economies.
