>Mfw the one thing we need most in life is the one thing that we die from in which we can't escape death.
Oxygen.
I know this may sound ridiculous but can there be a substitute to oxygen?
has anyone ever tried?

There is anaerobic respiration, but we wouldn't be able to have the same energy output.

use sensible English and role again.

How does Oxygen kill us?

>> No.4051051

Oxygen is bad shit at high pressures.

But still, I refuse to try to answer such a poorly worded question.

Your body is full of a powerful solvent that can dissolve rock. The oxygen in the air is the least of your worries.

You could try another potent electron acceptor. A full range of sulfur-based life is possible, but the ecosystems tend to be unstable and low-energy. Molecular oxygen is a gas but molecular sulfur is a yellow solid, and that's kind of a PITA for living things. Sulfur life winds up using hydrogen sulfide a lot, but that's an acid and also kind of a PITA.

If you wanted to get really alien, you could have fluorine-based life with bones made out of Teflon...
