Talk:Trees cause pollution

Apparently trees do cause most pollution. The comment that the sun doesn't cause pollution is bogus as well. Just look at the northern lights. Huge problems with solar flares. ^{— Unsigned, by: Dpmartin / talk / contribs}

Maybe we should decide what we mean by "pollution"? If we mean "something which could be bad in excess or under certain circumstances" then I'm sure you could argue that "trees cause pollution". But with that definition then everything is pollution.

If we define pollution as "an unwanted environmentally-damaging waste product of an industrial process" then tress don't cause pollution and neither does the sun. Other definitions are possible--Bob^{Spring is sprung!} 11:40, 14 January 2012 (UTC)
