Renewable Resources Can be depleted or degraded.

Sustainable Yield: the highest rate at which a renewable resource can be used without reducing its supply.

Example: over-farming the land leading to soil erosion, clear-cutting forests.

Environmental Degradation: when we exceed the natural replacement rate of the resource.

Example: groundwater depletion, water pollution.
