The big picture
Six ideas, one chapter.
| Idea | Remember |
|---|---|
| Where things start | Almost everything starts as a plant, an animal or the ground. |
| Shared by everyone | What one user takes changes what is left for the others. |
| Soil | Soil forms slowly. Bare ground loses more soil in rain. |
| Forests | Clearing a patch stops two jobs: animal homes, and roots holding soil. |
| Renewable or not | A renewable resource refills in time. A non-renewable one does not refill in our lifetime. |
| Using less | Reduce: use less. Reuse: use again. Recycle: break down and remake. |
