ALGAE LOUNGES
If you ever find yourself in a luxury penthouse or even a high end bar, you may stumble upon an algae lounge. These specialty rooms have walls covered in a thick layer of genetically enhanced algae that yields a high oxygen output, allowing guests to enjoy a breath of fresh air. In cities, these are basically the only places to inhale air that doesn’t taste of steel, they’re also perhaps the only places that outlaw smoking entirely. The lounges are often outfitted with plush couches with pillows and blankets to maximise comfort.
