Algae blooms primarily cause decreased oxygen in the water. When algae die and decompose, the decomposition process consumes a significant amount of oxygen, which can lead to hypoxic (low oxygen) or anoxic (no oxygen) conditions. This can have detrimental effects on marine life, leading to fish kills and negatively impacting other organisms in the ecosystem.
