You're saying the CO2 risk is OK, because they have oxygen masks.

That's like saying, increasing the risk of crashing a car is OK, because we'll have airbags.

What I'm saying is (unless you're PETA), the welfare and safety of your fellow human beings will trump most other things.

There's a reason the crew already has oxygen masks.

The masks are there to survive sudden cabin decompression at high altitudes where the atmosphere is too thin to breath. There is only enough oxygen to last a few minutes.
