Phase 5: Air
5 Human Impacts on the Environment by Crash Course
5 Human Effects on the Environment
(As described in this video. Other effects include pollution.):
- Deforestation
- Desertification
- Climate Change
- Non-Native Species
- Over Harvesting
Why are ecosystems important?
They provide ecosystem services that:
- Support Services - create a replenish the foundation of the earth's biological systems (carbon, water, nitrogen, and phosphorus cycles)
- Provisioning Services - giving us the raw materials we need to live (for example, food, water, fiber, fuel)
- Regulating Services - ecosystems moderate systems that can be dangerous if they don't function properly (for example, decomposers break down dead organisms, plants help filter water, regulate flood and erosion, and absorb carbon that regulates climate)
- Cultural Services - ecosystems give us places to play, scenes to inspire us, and things to discover and learn about

This phase is all about the current state of nature and the main problems our world is facing. These are the problems that our kids will be faced with. Hopefully, we are giving them the skills knowledge today that they can use to address these problems in the future.

Learn about 5 human impacts on nature. Don't get excited, there are certainly more, these are just the ones that Frank decided to talk about. You'll learn about more environmental problems as you go through this phase. But Frank has a lot of great points to make, plus he covers ecosystems services - what nature provides us for free.
