Quote:Simply for the reason that outcasts cant rely on the cardi-supply through their masks forever, they need to get back to the planet from time to time or they will die as well.
Logic failure there.
The air on Malta has some cardimine in it due to the grass.
The cardimine in the air is what would keep Outcast's alive without masks.
Why would a mask, which is a pure source of Cardimine, be well..worse for them?
The logic in your statement means that they need oxygen too..which they get everywhere.
