Revealing mistake: When Bond hits the button to throw the space station out of its gravity and sends everyone out of position look at the command console manned by the two Drax henchmen, the prop used for the console laughably moves back and forth during the commotion.
Continuity mistake: When Bond is looking at the airport through the telescope in Rio he sees the Drax cargo plane coming down the runway but just seconds before in the wide shot of the whole airport there is no plane on the runway or anywhere near it.
Revealing mistake: When Jaws brings Bond and Holly to the command center of the space station Drax is sitting down in his chair then suddenly in the next shot he's standing without having moved.
Continuity mistake: Bond manages to shut off the gravity in the whole station, but when the bad guys begin their battle with the Marine astronauts the bag guys are walking towards the airlock hatch as if they have full gravity.
Factual error: There are way more Marines in the American shuttle than it should be able to hold.
Audio problem: When Drax greets Bond on the island, as he's saying the part about the snake, you hear him talk, but his mouth isn't moving.
Revealing mistake: When the passengers disembark from the shuttle the camera appears to be on the side of the space station, but look at the stars on the bottom of the screen - they are moving a lot faster than the stars on the top of the screen, both sets of stars should be moving at the same speed.
Continuity mistake: When Bond throws the chain over the cable there are two handles attached to the chain, but when they slide away the handles on the chain are gone.
Other mistake: Bond is pushed from the plane without a parachute, but can see he wearing a altimeter on his wrist.
Revealing mistake: When the shuttle ejects the engines you can see the support wires used to pull off the boosters.
Revealing mistake: During the boat chase with Jaws the close up of Bond driving the boat reveals at the bottom of the screen part of the camera rig holding the camera in place. In other long shots these brackets are missing from the boat.
Continuity mistake: When Bond's gondola goes under a bridge an encounters the hearse, the canal they're in changes completely. The street on the right disappears and is replaced by a brick wall.
Continuity mistake: When Bond arrives to Venice he grabs a card from Venini Glass. From the immediate opposite angle the cards is gone.
Visible crew/equipment: After Bond/Roger Moore's stuntman throws the pilot out of the plane, a safety bar connecting the plane and the stuntman's body is noticeable.
Visible crew/equipment: When the pilot aims a gun at Bond, there's a black bulky object reflected (filming crew or equipment) on the ice cube which disappears in the opposite shot.
Continuity mistake: Before Bond jumps out of the boat with the delta wing glider, the sky swaps from sunny to cloudy and back to sunny, between shots.
Continuity mistake: After Bond and Goodhead jump on the grass and he says "for saving my life" her arm swaps from being around his nape to by her side.
Continuity mistake: After Jaws' cable car crashes and everything explodes, he appears inches away from a table and chair with a 7UP ice cube on. A shot later a girl comes running and the table is 3 meters away, lying fallen on the floor.
Revealing mistake: During the cable car scene, when Bond and Goodhead are sliding down, not only is the image in the background a still image (check the boat left of the island, and the waves next to the coast on the right), but the very same shot of them sliding downwards is used twice.
Factual error: The station's gravity is turned on and off several times before and during the battle. The film establishes the gravity is on because the station is rotating. Bond and Holly turn off the gravity to prevent the Americans from being shot down. Then, after the American Marine shuttle docks, gravity is restored and is never seen being deactivated again. However, the station begins to take on serious damage from the battle and literally begins falling apart. Even setting aside the fact that the mass shifts would affect the station's ability to produce gravity, the external shots of the damaged station don't indicate it's even rotating anymore, but everyone inside is still able to move around as if gravity is still active up to the final destruction of the station.
Answer: They would die or escape and go feral, as would zoo animals, farm animals etc.
