Re: (TFT) Mars - Plants get too hot on Luna.

[Rick Smith <rsmith@lightspeed.ca>]

Oh, yes, plants on Mars will need to be in hot 
houses for the long term.  Plants use oxygen 
during stages of their lives (when germinating
for example, when they are sick and a small 
amount at night).  Also if the CO2 level gets
too high they are stunted.  We can not just
compress the Martian air for plants.  The CO2
level is too high.

There will have to be serious terraforming 
before any 'higher' plants can be put on the
surface.  Litchen, bratchophites (sp?), and
blue green algae would be the first colonizers.
