Question

“Wetlands are vital for human survival.” List any three importance of wetlands.

Answer 1

1. Biodiversity Support: Wetlands serve as habitats for diverse flora and fauna, including many endangered species. They provide breeding grounds for migratory birds, nurseries for fish and amphibians, and homes for numerous plants and animals adapted to wet environments.
2. Water Regulation: Wetlands act as natural buffers against floods by absorbing and holding excess water during heavy rains. Conversely, they also help prevent droughts by releasing stored water during dry periods. This regulation helps stabilize water flows in rivers and streams, maintain groundwater levels, and reduce erosion and sedimentation.
3. Water Purification: Wetlands filter and purify water by trapping sediments, nutrients, and pollutants from runoff and groundwater. They play a critical role in improving water quality before it enters larger water bodies like rivers, lakes, and coastal areas. This function is essential for providing clean water for drinking, irrigation, and supporting aquatic ecosystems.
