Sure, a glass box of plants sounds romantic, but let me spell out why it’s a nightmare in the wild. You’ve got to balance light, CO₂, and water, and any leak turns the whole thing into a floating sauna. Pick plants that actually thrive on the solar panel’s weak spectrum, keep a salt‑water cycle that won’t evaporate faster than you can collect rain, and you’ll still be lugging a whole greenhouse on your back. It’s a neat idea, but the logistics of maintaining a tiny ecosystem outweigh the convenience of a “no‑kitchen” backpack. And trust me, nobody ever leaves a glass box in a blizzard without it breaking.

Yeah, a green backpack would look great on a selfie, but every leak turns it into a swamp, and keeping a solar panel dry while you’re moving? That’s a recipe for a malfunction. I’d rather stash a stove, a water‑filter, and a handful of seeds than a half‑broken bio‑reactor.
