Wetlands play a crucial role in the environment by providing various benefits such as flood control, water purification, habitat for wildlife, carbon storage, and erosion control. They act as natural sponges, absorbing and storing excess water during heavy rainfall which helps in reducing flood risks. Wetlands also filter and purify water by trapping sediments and removing pollutants, thus improving water quality. They provide habitat for a diverse range of plant and animal species, contributing to biodiversity. Additionally, wetlands store carbon, helping to mitigate climate change, and their vegetation helps in preventing soil erosion. Overall, wetlands are vital ecosystems that support both the environment and human well-being.
