The rapid industrialization and urbanization in recent times has altered the climate of the planet Earth. The abrupt hike in the level of GHG has not only affected the temperature, rainfall pattern, humidity, snowfall etc., but at the same time, the biodiversity has also been impacted to a great extent. It is now the right time to develop a register for carbon sequestration activity series by coastal vegetation. In several conferences and conventions, the terrestrial forest vegetation is given priority for studying carbon sequestration. The blue carbon vertical, which basically includes the stored carbon in seaweeds, tidal marshes, mangroves and seagrass meadows, has not yet been emphasized as the potential sink of CO2.
