World Wetlands Day, 2023

Wetlands support a wide range of biodiversity and help to maintain natural cycles. They replenish water resources and protect coastlines. They account for 4.7% of the Indian Geographical area. Today 30% of the Indian wetlands have been lost. And 35% of wetlands have been lost at the world level. To create awareness about the importance of wetlands and protect them from degrading, the UN and other international organizations celebrate World Wetlands Day.
