Wetlands are among the most productive and ecologically significant ecosystems on the planet, providing a multitude of ecosystem services that support both environmental health and human well-being. These ecosystems, which include marshes, swamps, bogs, and mangroves, function as vital interfaces between terrestrial and aquatic environments. Their complex structure and dynamic nature allow wetlands to offer a range of provisioning, regulating, supporting, and cultural services that are crucial for maintaining ecological balance and supporting biodiversity. One of the most apparent benefits of wetlands is their role in water purification and filtration. Wetlands act as natural filters, trapping sediments, nutrients, and pollutants from surface water before it enters rivers, lakes, or groundwater systems. This filtering capacity reduces the load of harmful substances such as nitrogen, phosphorus, heavy metals, and pathogens, thereby improving water quality and protecting downstream aquatic ecosystems. Plants and microorganisms within wetlands absorb and break down contaminants, making wetlands highly efficient in detoxifying water and mitigating the effects of agricultural runoff, industrial effluents, and urban wastewater. In addition to water purification, wetlands play a crucial role in regulating water flow and reducing flood risks. Their ability to store large volumes of water during periods of heavy rainfall or snowmelt helps prevent flooding in surrounding areas. Wetlands act like natural sponges, absorbing excess water and releasing it slowly, which stabilizes water levels in rivers and reduces the severity of floods. This regulatory function is particularly important in low-lying areas prone to seasonal flooding or in urban regions where impervious surfaces increase runoff and flood hazards. Similarly, wetlands contribute to groundwater recharge, allowing water to infiltrate slowly into aquifers, which sustains water availability during dry periods and supports agricultural and domestic water supplies. Carbon sequestration is another critical ecosystem service provided by wetlands. These ecosystems are capable of storing large amounts of carbon in their soils and vegetation, particularly in peatlands and mangroves. By capturing carbon dioxide from the atmosphere and storing it in organic matter, wetlands mitigate the impacts of climate change and help regulate the global carbon cycle. Mangroves, for
