* Coal: Non-renewable. Coal forms over millions of years from decomposed plant matter, and we're using it up faster than it can be replenished.
* Dirt: Renewable (sort of). Dirt is made from weathered rock and decomposed organic matter. While the rock takes a very long time to break down, organic matter replenishes at a faster rate, making it more renewable. However, topsoil erosion and depletion are significant concerns.
* Evergreen Trees: Renewable. As long as we manage forests sustainably, evergreen trees can be replanted and harvested for their wood and other products.
* Oxygen: Renewable. Oxygen is constantly being produced by plants through photosynthesis.
* Silver: Non-renewable. Silver is a metal found in the Earth's crust and is mined. It's a finite resource.
* Tomatoes: Renewable. Tomatoes are plants that can be grown and harvested repeatedly.
* Trout: Renewable. As long as fishing is managed sustainably, trout populations can be replenished naturally.
* Water: Renewable (with caveats). Water is constantly being cycled through the environment through evaporation, precipitation, and runoff. However, clean, freshwater sources are limited, and pollution can make them unusable.
In Summary:
* Renewable: Evergreen trees, oxygen, tomatoes, trout, and water (with limitations).
* Non-renewable: Coal and silver.
* Partially renewable: Dirt.
