"reducing world population, reducing per-capita resource use, reducing the role of fossil fuels, improving energy efficiency, increasing the efficiency of food production and distribution, "and enhancing efforts to manage as reservoirs of biodiversity and ecosystem services, both in the terrestrial and marine realms, the parts of Earth's surface that are not already dominated by humans."
