Ok, so they're growing some kind of microorganism. But I feel like for years I heard that spirulina would become an important tool for feeding the planet ... but mostly the people that consume it do so in pretty small amounts, and it doesn't seem to be taking over the world.

Is the scale of production any different?

> SCP represents options of fail-safe mass food-production which can produce food reliably even under harsh climate conditions.

Let's hope we can beat some sense into ourselves before we get there.
