If I'm going to create a false atmosphere on MARS, by genetically engineering a lichen to live in an extremophile environment, then I have to look for desirable genes at the bottom of the ocean.

I need to take the "hardiness genes" from the bacteria that is most genetically similar to the green alga or cyanobacterium. This gene has to come from the bottom of the ocean. So, take that gene (it probably has something to do with metabolizing nitrogen, but that's another story) and incorporate it into the lichen's genome to make it super hardy, so hardy it can live on the surface of Mars with minimal "fuss" and if I play my cards right, the lichen will hence produce large concentrations of oxygen over time. I have to travel to the bottom of the ocean to "green" Mars.

In the end, the change in the concentrations of gases in the atmosphere would never make the air breathable? In my current opinion, it would just make it possible for material science to make a space suit that would be lighter, more comfortable, etc?

I like to pretend like I could do it all myself. OH WAIT, I could. I only need other people's money, other people just get in the way.

Today I was thinking about the potential problems a genetically engineered lichen could pose to humans, from a human health standpoint.

Long story in cleaning out lots of moldy shit from the fridge. I'd have to go ahead and assume that since the organism would be such extremophile to cold temps (low O2 concentrations) perhaps in this case a 98.6 deg temp would be an even larger asset, allowing for complete resistance to infection and/or colonization; until eventual mutations which occur @ frequency/time.

Mycology would be such a fun field of research...

SO, I guess it wouldn't matter if mutations occurred at frequency/time if there were enough geneticists sampling current populations of the organism frequently enough to catch any potential mutations that could enable the extremophile to colonize tissues...
