Sushi is the Answer?

Kelp forests, in the oceans, are a surprisingly good way of removing carbon dioxide from the atmosphere (and countering climate change) but these algae are seriously endangered by voracious sea-urchins who can remain viable but inactive at times of food shortage. It is claimed by a company, called Urchinomics, that the solution is simple (https://www.theguardian.com/environment/2020/feb/02/why-sushi-could-be-the-solution-to-a-sea-urchin-invasion-aoe). All you have to do is convince the world populations to develop a taste for sushi, especially the delicacy of sea-urchin gonads. I must admit that it is surprisingly tasty.
