Hi Kevin,

I am being told that the night time respiration excedes the day time 
inspiration.... The biologist feels that these plants, being invasive, 
are crowding out other indigenous plants and prohibiting biodiversity 
and therefore man should intervene to remove them and to replant a 
variety of plants....

I will attempt to make the argument that according to the Gaia theory, 
the earth is intelligently choosing the exact plants she needs in exact 
quantities to repair, restore, regenerate and reorganize itself and 
that furthermore the principle of succession is well established and 
that therefore a plant's inasiveness is only as long lived as its 
uselfulness in  preparing the soil for the next generation...
