| what are the 4 types of ecosystems | Provisioning, regulating, cultural and supporting |
| Define the ecosystem service Provisioning | Any type of benefit to people that can be extracted from nature. |
| Define the ecosystem service Regulating | The benefit provided by ecosystem processes that moderate natural phenomena. |
| Define the ecosystem service Cultural | Non-material benefit that contributes to the development and cultural advancement of people. |
| Define the ecosystem service Supporting | Earth helps sustain basic life forms, and the whole ecosystem and people. |
| Give an example of Provisioning | Drinking water, timber, woof fuel, natural gas, oils, plants for clothes, other materials for medical benefits |
| Give an example of Regulating | Pollination, decomposition, water purification, erosion, flood control, carbon storge, climate regulation |
| Give an example of Cultural | Local, national, global cultures, building of knowledge and the spreading of ideas, creativity born from interaction with nature (music, art, architecture). |
| Give an example of Supporting | Photosynthesis, Nutrient cycling, creation of soils, water cycle. |
| What are 3 examples of a natural capital? | Air, water, land. |
| Define non-market values | values not included in the price of a good or service. |
| What does the ecological footprint measure? | How fast we consume resources and generate waste compared to how fast nature can absorb our waste and generate new resources. |
| Define sustainability. | Living within our planet's means, such that earth and its resources can sustain us and the rest of earth's life indefinitely. |
| Define living sustainably | Living off natural income replenished by earth's ecosystems, and not depleting/degrading the earth's natural capital that supplies this income |
| Define carry capacity | The maximum number of individuals of a given species that a given area can sustain indefinitely w/o depleting/degrading those resources. |
