Interesting links. I quickly browsed all three of these. Tell me if
you
see it differently
but what I get from these is: Some trees do produce pollution but
most
trees also
absorb CO2 and "clean" the air.

I don't consider CO2 a pollutant. Those that do should just off
themselves
and stop polluting the air by exhaling.

Perhaps you should seal yourself in an environment with elevated levels
of CO2, then.
