Is/was there anything (device, animal, plant, etc.) on the International Space Station that will be destroyed/dead if that object returns to Earth? (Assume that thing/animal is brought in, for example, the Soyuz with the astronauts in a soft re-entry)
It could be either fabricated/manufactured/born there or traveled from the Earth and changed with the time.
For example, if you bring an Anglerfish to the surface of the ocean, it will die because of the pressure difference.
Note: I am NOT saying what part of the ISS is going to be destroyed (or not) when the ISS reenters.
