Explanation
World Wetlands Day is observed on 2nd February every year to raise awareness about the importance of wetlands and their conservation. Wetlands are unique ecosystems that provide a wide range of ecological, economic, and social benefits, including water storage, flood control, soil conservation, and habitat for many species of plants and animals. However, wetlands are under threat due to human activities such as pollution, deforestation, and urbanization. World Wetlands Day is an opportunity to educate people about the critical role that wetlands play in maintaining the balance of our planet's ecosystems and to encourage action to protect and conserve these valuable habitats. The theme for World Wetlands Day in 2022 was "Wetlands and Water".
