the fundamental “problem” -- is there enough land for everything?
| Grade | Discipline | Core Idea |
|---|---|---|
| 6-8 | ESS3.A: Natural resources |
Humans depend on Earth's land, ocean, atmosphere, and biosphere for different resources, many of which are limited or not renewable. Resources are distributed unevenly around the planet as a result of past geologic processes. |
| 6-8 | ESS3.C: Human impacts on Earth systems |
Human activities have altered the biosphere, sometimes damaging it, although changes to environments can have different impacts for different living things. Activities and technologies can be engineered to reduce people's impacts on Earth. |
| 9-12 | ESS3.A: Natural resources |
Resource availability has guided the development of human society and use of natural resources has associated costs, risks, and benefits. |
| 9-12 | ESS3.C: Human impacts on Earth systems |
Sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources, including the development of technologies. |
