    Algae doesn’t capture it for long. Trees do it for longer but not long enough to be more then a speed bump. Unless we start dumping algae and trees into giant pits and sealing them up three is no long term carbon capture.

      Not true, it depends on how it’s contained. Drying algae and removing the water will stop it from decomposing. Think of seaweed used for sushi except ground up into a very dense powder. Algae will decompose if left hydrated in the sun though.
