Wetlands are transitional zones between terrestrial and aquatic ecosystems. They act as natural filters, support unique biodiversity, and play a vital role in flood control and groundwater recharge.
Wetlands are threatened by pollution, land reclamation for agriculture or development, invasive species, and climate change-induced drying or flooding.
Conservation measures include legal protection of wetlands, restoring degraded wetland areas, using constructed wetlands for wastewater treatment, and involving local communities in sustainable wetland management.
