the greening of Mars continued

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...
