6. Impact
 How does my landscape affect the world?
 Butterfly effect
 Ex: Back to the Future
 Ex: Weather

7. Impacts
 Sensitive dependence on initial conditions
 EX: How does misuse/overuse of chemicals affect our future?
 Landscape is a mini-ecosystem that affects the
surrounding environments (landscapes) and thus the
surrounding ecosystems (world)

8. Parts of the Landscape
 Plant materials
 Hardscapes
 Maintenance
 Other inputs/outputs
