What is the main ecological risk of converting land to cropland despite productivity gains?
|
Loss of carbon sinks and soil degradation |
|
converting land to cropland can cause soil degradation and carbon sinks. |
Soil degradation from cropland can be caused my the roots and the nutrients from the soil being downgraded from plants before.
also carbon is going down into the soil too. |
