This is so freaken insane! OMG

kinda what hppens when your life is so easy, you run out of real concerns...

Jesus.

I'm going to assume they are being symbolic about deforestation in general, not that particular tree. But yes, it's sad the lengths people will go for a a few trees or a man that died 2000 years ago.

The funny thing is a tree doesn't produce as much oxygen as a newly planted tree. So basically if the lumber jack chops down an old tree and plants 3 younger trees in its place; it's actually better for our environment.

We'll log the rest of the planets later.

Especially if that lumberjack uses varying sizes of internal combustion engines to process the old tree, some of which is converted to charcoal, which is in turn used to grill a few tasty-if-not-very-filling Spotted Owls...

That is a pretty tall claim I call BS. Please cite your source.

Little Known or Interesting Factoids About Tree Physiology
• Trees both produce AND consume oxygen.
• Young forests capture more carbon from the atmosphere than old forests.
• Old forests have more stored carbon in the biomass than young forests.
• The food that trees produce for themselves are sugars.
• The purpose of photosynthesis is to capture and store energy.
• Green light is the only part of the visible light spectrum that plants can’t use.
• The timing of Autumn color change is largely controlled by lengthening nights.
• Conifers lose needles each fall, just the same as broad-leaf trees.
• Trees grow TWO rings each year, one in the spring and another during the summer.
• Swamp trees don’t necessarily prefer swamps.
• Tree species have highly variable requirements for light, nutrients, and moisture.
• Oceans produce more oxygen and store more carbon than forests.

I think you are confusing carbon capture with oxygen production. But maybe I'm reading this wrong.

Well you can look at this study

http://treephys.oxfordjournals.org/content/22/2-3/105.full.pdf

Summary Our primary objective was to present and test a new technique for in vitro estimation of respiration of cores taken from old trees to determine respiratory trends in sap- wood. Our secondary objective was to quantify effects of tree age and stem position on respiratory potential (rate of CO2 pro- duction of woody tissue under standardized laboratory condi- tions). We extracted cores from one to four vertical positions in boles of +200-, +50- and +15-year-old Pinus ponderosa Dougl. ex Laws. trees. Cores were divided into five segments corresponding to radial depths of inner bark; outer, middle and inner sapwood; and heartwood. Data suggested that core seg- ment CO2 production was an indicator of its respiratory activ- ity, and that potential artifacts caused by wounding and extrac- tion were minimal. On a dry mass basis, respiratory potential of inner bark was 3–15 times greater than that of sapwood at all heights for all ages (P < 0.0001). Within sapwood at all heights and in all ages of trees, outer sapwood had a 30–60% higher re- spiratory potential than middle or inner sapwood (P < 0.005). Heartwood had only 2–10% of the respiratory potential of outer sapwood. For all ages of trees, sapwood rings produced in the same calendar year released over 50% more CO2 at treetops than at bases (P < 0.0001). When scaled to the whole-tree level on a sapwood volume basis, sapwood of younger trees had higher respiratory potential than sapwood of older trees. In contrast, the trend was reversed when using the outer-bark sur- face area of stems as a basis for comparing respiratory poten- tial. The differences observed in respiratory potential calcu- lated on a core dry mass, sapwood volume, or outer-bark sur- face area basis clearly demonstrate that the resulting trends within and among trees are determined by the way in which the data are expressed. Although these data are based on core seg- ments rather than in vivo measurements, we conclude that the relative differences are probably valid even if the absolute dif- ferences are not.

So what this means is the older trees can consume more oxygen than it produces.

I like to get in touch with nature too, when I go hunting

Even after reading the study he found, I'm not seeing it.

I can see that replacing 1 old growth tree with 3 young trees might have a result that's more CO2 -> O2.

I disagree. There's a LOT wrong with people who belong to violent extremist organizations like Earth First. And I mean besides just their silly behavior, crying in the woods.

Taking in more CO2 creates more byproduct of oxygen (using CO2, water and hydrogen). So a young tree a sorting more CO2 is creating more oxygen byproduct.

Where is the oxygen coming from? You know, that it's putting out.

Well hydrogen is h, water is h2O, CO2 is CO2. The carbon is scrubbed to pull the carbon into sugars for growth. That would leave the waste being oxygen.

I'm all for the trees, and environment, but sweet something...of someplace! This is overboard.

 

[Denny Crane]

So it's not storing the CO2.

You said the tree sorting more CO2. I assume you meant "stores more"

 

[magnifier661]

Of course it stores CO2. What happens when you burn wood?

But how much is used to burn wood? I would argue wood being cut is used for building, especially trees that size. Also, compost is made from the saw dust or pressed wood. If a house or building using that wood is around for over 25 years, the new trees net way more oxygen

 

[Denny Crane]

It doesn't store CO2.

It takes in CO2, emits O2, and converts the rest to sugar (carbohydrate).

When you burn wood, the carbon from the carbohydrates combines with O2 from the water in the plant to release C02, methane, and a few other things (the methane has carbon and hydrogen).

You are right, but where do you think the sugars go?

Mostly to grow the tree bigger. What it doesn't need is stored like we store fat.

 

[MARIS61]

Over 99% of the world's old growth has been logged, 80% of it in the last century. Not one single tree will ever be replaced.

Each day there are less old trees and soon there will ony be photos for reference.

Bottom line, old trees provide homes, food, protection, flood control, erosion control, hunting grounds, and symbiotic relationships which are unavailable anywhere else on the planet. Species of flora and fauna are going extinct by the tens of thousands as the world's last few virgin forests fall to the axe. Many, if not most, of our most important drugs come from old groth forests and that is where scientists see the best chance to find eventual cures for most diseases.

Ding ding ding! Cellulose and plant parts! All which contain carbon right?
