Wetlands are crucial for maintaining biodiversity because they provide a unique habitat that supports a wide variety of plant and animal species. The diverse and interconnected ecosystems found in wetlands offer food, shelter, and breeding grounds for many species, including migratory birds, fish, amphibians, and insects. Additionally, wetlands help to filter and purify water, control flooding, and store carbon, making them vital for supporting a healthy and balanced ecosystem. The preservation of wetlands is essential for protecting biodiversity and ensuring the continued existence of numerous species.
