Environmental impacts of low-density land development -- aka Sprawl:
		• Water pollution:  reduction in water quality    through creation of impervious surfaces * Air pollution:  On-road vehicles impact on    urban health and add greenhouse gases * Soil erosion * Habitat loss and fragmentation: loss of local    biodiversity * Loss of farmland * Inefficient resource use: and depletion of non-    renewable resources (e.g. petroleum);    increased energy consumption
