Mangroves play a crucial role in combating estuarine acidification by stabilizing sediments and reducing acid sulfate runoff. Their root systems trap organic matter, promoting microbial processes that neutralize acidic conditions. Mangrove vegetation absorbs CO2, helping buffer against pH drops caused by elevated carbon dioxide levels. By improving water quality through filtration and nutrient cycling, mangroves create a more stable estuarine environment. Additionally, they act as a protective barrier, mitigating the impacts of external pollution that could exacerbate acidification.
