Insensitivity of local administration is another cause for visual pollution. For example, poorly planned buildings and transportation systems create visual pollution.
These can reduce damage and erosion while simultaneously providing ecosystem services such as food production, nutrient and sediment removal, and water quality improvement to society [59] Example of human caused habitat destruction likely capable of reversing if further disturbance is halted. Uganda.
