The human activity that primarily causes excessive blooms of algae in lakes due to the degradation of water quality is use of fertilizer in farming. Fertilizers often contain high levels of nutrients, particularly nitrogen and phosphorus, which can runoff into water bodies and contribute to algal blooms when they enter the water.
