Global warming can exacerbate water pollution in several ways. Warmer temperatures can lead to increased algal blooms in bodies of water, which can create toxins and deplete oxygen in the water, harming aquatic life. Additionally, heavy rainfall events, which are expected to increase with global warming, can lead to more runoff carrying pollutants into water bodies. Warmer temperatures can also cause more bacteria and pathogens to grow, potentially affecting the safety of water supplies.
