Episode 660 Marine Permaculture

Brian von Herzen, the CEO of the Climate Foundation, describes his project – the development of large seaweed farms in the oceans around Asia (their first one is near the Philippines). The algae are anchored to a circular platform that is lowered at night so the algae can absorb the nutrients that lie in the deeper levels, and then is raised in the daytime to use photosynthesis and provide food for the increasing human population.
