Trees,generally,are used to remove carbon dioxide from the atmosphere.Other methods need to be considered.NASA(National Aeronautics and Space Administration)uses iron lime to increase the plankton uptake from the ocean bed.We can remove the carbon through the practice of shellfish farming.In French Polynesia,oysters mean pearl oyster farming.An independent assessment of the shellfish industry would be required to determine the carbon sequestration and generate carbon offsets through this method.CO2 sink in pearl oysters shell,called MOP(Mother Of Pearl)can be allocated into precious button and objects or powder in poultry farming.
