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.


Some of it depends on what you consider
"pollution" and what you consider "cleaning". Overall the statement that
"Trees
cause more pollution than automobiles do." is probably incorrect at worst
and
misleading at best.

In certain cases, for certain substances, trees probably do produce more.


Still, it just goes to show that there are almost never simple answers. It
takes research
and critical thought to properly asses most issues. It is my belief that
there are plenty
or people on all "sides" that should research and think a lot more before
speaking or
else just shut up.

You mean like algore? (as in the shutting up part)


Thanks for the links.
