How Algal Blooms Affect Aquatic Ecosystems and Water Quality
Algal blooms, characterized by the rapid overgrowth of algae in water bodies, are a growing environmental concern worldwide. These blooms, driven by natural and human-induced factors, significantly impact aquatic ecosystems and degrade water quality. This article explores how algal blooms disrupt aquatic life, alter ecosystems, and affect the availability of clean water. What Are Algal Blooms? An algal bloom is the excessive proliferation of algae in freshwater, marine, or brackish water systems. These blooms are often triggered by nutrient pollution, warm temperatures, and stagnant water. While some algal blooms are harmless, others, known as harmful algal blooms (HABs), produce toxins that pose serious threats to ecosystems, animals, and humans. The Impact of Algal Blooms on Aquatic Ecosystems Oxygen Depletion Algal blooms consume oxygen during decomposition. This leads to hypoxic (low oxygen) or anoxic (no oxygen) conditions, suffocating fish, shellfish, and other aquatic organisms....
