Ecosystem Services
Rivers, streams and groundwater systems – replenished by rainfall – produce water that sustains all living things. Pollination allows fruit trees to produce fruit and other agricultural crops to grow. Forests sequester carbon, provide timber for wood products, and serve as home for wildlife. Fisheries are a source of food for humans and other species, and estuaries serve as nurseries for fish, shell fish and other marine life. All living creatures depend on such “ecosystem services” or the regular functioning of natural systems that contribute separate but connected strands in the web of life. Diverse and healthy ecosystems and the services they provide are key to sustaining life on Earth.
