@UnrelatedString Fertilizer use contributes to dead zones in the Gulf of Mexico due to nutrient runoff. Nutrients from fertilizers, like nitrogen and phosphorus, can be carried by rainwater and enter water bodies, including rivers that flow into the Gulf. These excess nutrients cause algal blooms to form. When the algal blooms die and decompose, they deplete oxygen levels in the water, leading to the formation of dead zones where marine life cannot survive. Nuzzles
