Global heating affects the water of the ocean. Too high a temperature
is
killing
the kelp forests of Tasmania's coast. This could cause extinction
of the species that shelter in the kelp. That includes many species
that grow much larger, but which start out as small larvae that
shelter in the kelp.
There is no shallow sea region between Tasmania and Antarctica —
no natural place where the kelp could move to. I wonder if it is
possible to make underwater platforms that kelp could grow on. This
would protect the kelp and the other species that depend on it.
They would have to be held up by flotation, as the sea bottom is too
deep for them to rest on. They would therefore circulate around
Antarctica. Perhaps they could use solar power to maintain a stable
latitude.
These might be economically valuable by acting as nurseries for fish
that people would catch. Can anyone tell me whether kelp sustains any
commercial fisheries? Can anyone tell me how to reach people that
might consider this idea?
