How would humans most likely function in an atmosphere that was 19% oxygen?

• They would suffocate in an atmosphere below 21.5% oxygen.

• They would be very healthy; our current atmosphere is 18% oxygen.

• They would be at risk of oxygen deprivation in an atmosphere below 19.5% oxygen.

• They would be exposed to toxic levels of oxygen; humans require an atmosphere of only 12% oxygen to

  survive.
