a couple days ago i was asking why you dont using a oxygen bottle for clean air.There are good areas in various biomes. Trees can act as natural filters, it's true , but I've felt as good in death valley as in dense pine forests. I think the key thing is to experiment with intuition as a guide
you said that pure oxygen can be pretty toxic.
Now i am thinking about it, what kind of oxygen are astronauts in space using then?
