Why there is rapid algae growth?

Rapid algae growth, often referred to as algal blooms, typically occurs due to an increase in nutrients, particularly nitrogen and phosphorus, in water bodies. These nutrients can come from agricultural runoff, wastewater discharge, and stormwater. Additionally, warm temperatures and ample sunlight further accelerate algal growth. Such conditions can lead to harmful effects on aquatic ecosystems, including oxygen depletion and the production of toxins.
