Mankind faces on-going challenges from rising temperatures and greenhouse gas emissions, both directly and indirectly impacting the planet. Blue carbon ecosystems, particularly mangroves, salt marshes and sea grasses offer a natural and effective solution to combat climate change. This ‘silent green sentinel’ acts as natural carbon storage sinks by trapping carbon dioxide (CO₂) in their silt and storing the trapped carbon within their biomass. Notably, the specifics of the ways in which mangroves store carbon remain a rather obscure issue, which renders the target of the current article worth exploring. This article, therefore, serves as the means to discover the process of carbon storage by mangroves, the challenges that it brings, and the issue of the conservation and, of course, restoration of the mangroves along with the corresponding successful model throughout the country.
