d. fishing

Industrial pollution, wastewater discharge, and fertilizer runoff add nutrients (nitrogen, phosphorus) or other pollutants that directly stimulate algal growth (eutrophication). Fishing alters food webs and can indirectly affect algal abundance, but it is not a direct source of the nutrients that produce blooms.
