Appreciating Nature's Services looks at an array of life-support services that humans receive from biologically diverse natural systems. The vital benefits provided by healthy natural economies include photosynthesis, plant pollination, maintenance of soil fertility, water purification, erosion and flood control, control of population and disease, genetic diversity, and recreational, spiritual, and aesthetic enjoyment of nature.
