World Wetlands Day is recognized on February 2, 2021 as a global celebration of wetland ecosystems, some of the most productive ecosystems of the world. The term “biological supermarkets” has been used to describe wetlands, given the immense biodiversity they support. Wetlands also provide several beneficial ecosystem services, including protecting and improving water quality, providing habitat for fish and wildlife, storing floodwaters, and maintaining surface water flow during dry periods.
