Good points... I had free-floating sargassum in mind,which is washing up in volume on beaches around the world, rather than kelp or something that has to be ripped up off the seabed. Sargassum is in a state of hyper-growth around the world. something has created optimal conditions for it. I suspect that whatever was taken from the ocean would quickly be replaced. Is there a calculable upper limit to the amount of sargassum that could be produced by the ocean if it were aggressively being removed? Not saying this idea is practical, but the goal was to be more practical than covering half the Sahara with algae growing ponds.
