Answer 2

Soil is a renewable resource because soil erosion ensures that there are always nutrients available to feed vegetation.

• Soil replaces itself during soil erosion, and so nutrients are freely available for vegetation to grow.
• The rate of soil formation exceeding degradation of soil makes soil a renewable resource.
• We need to ensure there is less degradation of soil, so that the benefits of soil erosion, are fully absorbed by the soil.
• There are plenty of nutrients in the soil, and the fertility of the soil needs to be maintained.
