Largely as a result, scarcities of renewable resources will increase sharply. The total area of high-quality agricultural land will drop, as will the extent of forests and the number of species they sustain. Coming generations will also see the widespread depletion and degradation of aquifers, rivers, and other water resources; the decline of many fisheries; and perhaps significant climate change.text/plainen-USIn CopyrightFisheriesRenewable energyForestsAgricultureWaterPopulationScarcityClimate changeEcosystemAbstractCopyright 1994 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
