In recent times, environmental stewardship of mangroves has provided the impetus to protect and restore these ecosystems for their inherent ability to protect coastal regions from climate change, sequester carbon dioxide as rich blue carbon, and support human well-being through a multitude of ecosystem services. Perhaps the most significant current direct impact is camel browsing. Common direct impacts to wetlands include filling, grading, removal of vegetation, building construction and changes in water levels and drainage patterns. Some of the most obvious results are loss of fisheries, increased flooding, increased coastal damage from cyclones, and increased salinity of coastal soils and water supplies. Mangroves are important to people because they help stabilize Florida's coastline ecosystem and prevent erosion.
