Identifying human impacts on the environment identify whether each of the following descriptions are true or false. to sustain fossil fuel resources, alternative sources of energy should be used. drip irrigation uses more water and is not in sustaining water use. limiting erosion, disposing of mining waste, and limiting water pollution from the mine sustain land use. deforestation is in sustaining trees.

In order to sustain the resources of fossil fuel, the alternative sources of energy like renewable sources of energy should be used. Thus, the given statement is true.  

Drip irrigation refers to the kind of micro-irrigation mechanism, which possesses the tendency to save water and nutrients by permitting water to drip gradually to the plant roots, either buried below the surface of the soil or from above the soil surface. Thus, the given statement, that is, drip irrigation uses more water and is not helpful in sustaining water use is false.  

Disposing of mine waste, restricting erosion, and restricting water pollution from the mine assists in sustaining the use of land is true.  

Clearance or deforestation refers to the removal of the stand of trees or a forest where the land is afterward transformed into a non-forest use. Thus, deforestation cannot be considered helpful in maintaining trees, hence the given statement is false.
