The impact of nutrient pollution on aquatic plant communities can be severe, often leading to algal blooms and reduced biodiversity. Excess nutrients, primarily from agricultural runoff and wastewater, can cause uncontrolled algal growth, which depletes oxygen levels in the water as the algae die and decompose. This process, known as hypoxia, can lead to dead zones where aquatic life struggles to survive. Additionally, shifts in plant communities favoring fast-growing algae over native species can disrupt food webs and overall ecosystem health.
