Emission Of Smog Ingredients From Trees Is Increasing Rapidly

Trees, Trees produce the pollution. Trees!

[clee1]

I can just see the eco-nuts rush out to advocate clear-cutting old-growth forests.

[Texas Eagle]

Ronald Reagan was right!

[xJones]

Between the trees and gaseous cows, we are doomed.

[GSlob]

Wasn't it discovered some 20 yrs ago by Ronald the Great's Interior Secretary Watts? What these princetonians are doing now is not a science proper, but a humdrum repetition in an attempt to catch up.

Two major sources of smog-producing chemicals are automobile tailpipes and natural emissions from tree leaves.

I always knew it was a good idea to log. Gentlemen, start your engines.

There is a definite contradiction in this article.

They do not define "pollution." Naturally released chemicals do not logically fall under such a heading.

Re: Naturally released chemicals

Explain your point. I'm having trouble understanding.

   Trees, Trees produce the pollution. Trees!

Looks out across the 'landscape' of our city, Dallas for instance, and witness the abundance of ... TREES!

Trees that only exist b/c of the extensive watering system (every house and homeowner PLUS commercial watering system) for as far as the eye can see from any 20 story building!

Didn't use to be that way "pre-man" ...

Although scientists knew that trees contribute substantial amounts of VOCs to the atmosphere, the rate of increase in recent decades was previously unrecognized.

"It's just one of those biological correlations," said Purves. "What you want is a fast-growing tree that doesn't produce a lot of VOCs, but that doesn't seem to exist."

The article is about how chemicals released from trees and other vegetation are a primary cause of "pollution."

My point is that such naturally produced chemicals cannot logically be classified as "pollution."

Encyclopedia Britannica: "Pollution is the release of harmful environmental contaminants, or the substances so released. Generally the process needs to result from human activity to be regarded as pollution."

[xJones]

You live near Dallas, too? Oh, man, we are done for. Consider the flatulent cow emissions also. bloviating bovines.

We might as well end it all; send all the cattle in Texas to the Amazonian rain forests and get it over with.

[JSteff]

"While clean-air laws have reduced the level of man-made VOCs (volatile organic compounds), the tree-produced varieties have increased dramatically in some parts of the country, the study found."

Didn't Reagan get mocked by the press for saying this very thing? Hmm?

[Restorer]

Flying across the eastern half of the country, mostly what you see looking down is ... trees.

I read a bit ago (somewhere) that there are more acres of forested land than there was at the beginning of the 1900's.

[Restorer]

New England and much of the southeast has been reforested as farmers in more favored areas such as the midwest become able to grow much more food per acre. 150 years ago, New England was almost all plowed fields. Today it is mostly forested.

Reminds of the time the greenies made a stink about oil on Oil Creek here in Pennsylvania and tried to force a clean-up. Only problem it isn't called Oil Creek for nothing, the stuff is natural, seeping right out of the ground in front of their little greenie wienie noses.

Doh, never mind.

[endthematrix]

Yeah. And those damn deer and geese too. Sportsman due more to support natural habitat than the "tree huggers."

What will they hug now???

Yeah but .. we didn't used to have much of an air quailty issue - when the wind stopped blowing - like we have now; nowadays, all the outlying suburbs around Dallas are populated, with man-planted, deciduous, fast-gowing trees like Maples et al; net result, if this article is true, additional emmissions into the atmosphere ...

The 'trees' that uses to inhabit the plains here in Tejas were much more protective of the water the would allow to 'evolve' from their leaves, not so with most of the varieties that are planted now ... the natural trees growing in this area have to be darned near desert varieties, given some of the droughts I've seen ...
