What do we do with algae?

Ever seen a fish hatchery? They have huge, open-air tanks full of water. These tanks must grow huge amounts of algae because they're pretty large and are full of fish shit, which would provide plenty of nitrates. So why don't we pay fish hatcheries to scoop out and bury that algae? EZ sequestration.

Because it's a liberal shithole that is spreading its liberalism to previously-conservative states.

But it's also the state that barely keeps you out of being third world

Farm it for fuel

How about spin it incredibly fast to produce Astaxanthin.
