Corrected entry: All throughout the movie humans are dying because they can't breathe on the planet. But then at the end of the movie all the humans are being ushered out without any masks or anything (specifically, when Parker looks at the camera you can clearly see he is not wearing a mask) and are breathing fine?

Correction: Don't know what version of this movie you are watching. Every human has a mask on at the end on the retail Blu-Ray disc release.
