It’s a short scene. Wall-e and Eva are zooming around outside the spaceship trying to rescue the plant from earth. (SPOILER ALERT!) And they do rescue it. But then Wall-e takes it out to show Eva while they’re both still outside the ship.So what's the problem with that? The problem is that space is very cold (-270°C), and dry, and a vacuum. Would that kill a plant? That probably depends on how long the exposure is for. I haven't actually seen WALL-E yet, so I don't know how long the plant is exposed to space, but it probably would actually survive if the exposure was short enough. Heck, even humans could likely survive space exposure for 30 seconds or so, and plants have the advantage of being able to grow back from
That’s right. In a movie that’s basically about the ecological consequences of our failure to properly manage our planet, the heroes wave a plant around in space. And the plant’s none the worse for it.
There's more discussion on whether the little plant would survive at Ask Metafilter.
