Document Summary

Goods that come from natural resources or services/functions that ecosystems carry out that have measurable economic/financial value to humans. Provisioning: goods taken directly from ecosystems made from natural resources (wood,paper,food) Regulating: natural ecosystems regulate climate/air quality, reducing storm damage & healthcare costs. Supporting: natural ecosystems support processes we do ourselves, making them cheaper & easier(bees pollinate crops) Cultural: money generated by recreation(parks, camping, tours) or scientific knowledge. Human activities disrupt the ability of ecosystems to function, which decreases the value of ecosystem services they provide. This has ecological (natural) and economic (money-based) consequences. Clearing land for agriculture/cities removes trees that store co2 (more co2 in atmosphere = more climate change = more storm damage & crop failure) Overfishing leads to fish population collapse (lost fishing jobs and lower fish sales in the future) Goods/products directly provided to humans for sale/use by ecosystems. Fish, hunting animals, lumber (wood for furniture/buildings) naturally grown foods like berries, seeds, wild grains, honey.
