If you used water today to brush your teeth, cook or quench your thirst, you should probably thank a wetland. World Wetlands Day, celebrated annually on February 2, is an opportunity to learn about the value and importance of wetlands. This year, it also serves as an opportunity to double down on our efforts to protect these vital natural spaces that are disappearing before our eyes. In a rapidly changing world, the more wetlands we lose, the more valuable the ones that remain.
