Though they play a vital role in sustaining the eco-system, the country's natural wetlands are falling prey to rising pollution and urbanisation The World Wetlands Day (WWD) was observed sporadically across India on February 2 and yet many of us are not aware about the richness and necessity of wetlands in our lives. While wetlands are nature's water storage and water purification zones, they are also a paradise for wildlife, fishing, angling and bird-watching, water sports, relaxation and rejuvenation. Scientists believe that wetlands are the kidneys of nature. Unfortunately, wetlands today have become mere dumping grounds for garbage, rapidly throttling the water bodies.
