Remember that over 70% of our oxygen comes from the ocean, not forests

That’s not what I said… I’m just saying that it’s not so harmful or detrimental that trees are cut down responsibly. They are a reusable resource. Also the corn belt in the USA in season provides more oxygen than the Amazon too

Well that's completely different from what the original comment you replied to said. They specifically criticized clearcutting forests, which is not responsible. I think to interpret their comment as anti-christmas tree farm or similar responsible forestry practices is... disingenuous.

I mean clear cutting trees isn’t inherently bad either. Again, they’re reusable and can be planted elsewhere. Clear cutting in certain areas isn’t bad. Indiscriminately clear cutting everywhere would be bad
elencus t1_iudssu0 wrote
I think at the very best you can claim that in some cases clearcutting forests is controversial and provides niche edge benefits. Why you are so insistent to point out cutting trees can be good, I have no idea.

Well-oxygen isn’t the only benefit of forests. Diversity and thriving ecosystems provide services that are critical. I just don’t think you can justify cutting the Amazon to the point of no return is “meh”. That’s just one example. Oxygen isn’t the talking point there.

And what about animal ecosystems?
Hardwood forest take close to 100 years to regrow fully. All those animals that require specific hardwood ecosystems can’t survive if we keep cutting down there homes.
MKQueasy t1_iuerbpa wrote
Those animals should have pulled themselves by the bootstraps and bought the forest as their property after investing in mutual index funds if they didn't want people cutting them down. They can only blame themselves for not participating in our capitalist society.

We do… the US has more trees now than it did 100 years ago
Acrobatic-Rate4271 t1_iuib4dn wrote
That's mostly because originally logging didn't replant trees and so a hundred years ago our tree stock was down from previous levels. States began legislating that logging required replanting so we're starting to get back to pre-logging levels but a plane flight over states like Oregon will give you an idea of just what clearcutting did to our forests before replanting was required by law.
jeoeker531 t1_iuieqkq wrote
Regardless there’s a net gain of trees on earth
Acrobatic-Rate4271 t1_iuihiew wrote
Yes, it's good that we're planting trees but something to keep in mind is that photosynthesis (the reaction that consumes CO2 and produces O2) occurs in the leaves so older, more mature trees consume more CO2 and product more oxygen than younger trees. Even with replanting, the cutting of old growth trees and rain forests results in a net loss in CO2 capture and conversion to O2 unless your replanting significantly more trees than you're cutting. This also ignores the loss of undergrowth associated with logging.
I'm not saying we need to stop all logging, just pointing out that it's not as straightforward as it seems on initial inspection.

And what would be the effect of fucking up 30% of the supply of anything?
jeoeker531 t1_iudgt54 wrote
Not so severe when you can replace it. Trees are replaceable. And supplies of one thing aren’t as vital as supplies as others. So fucking up 30% of something might not always be a big deal. Trees are reusable and don’t provide the majority of oxygen
NemeshisuEM t1_iudheha wrote
Yeah? How long does it take to replace a healthy, mature forest?
Also, have you looked at what is it in the oceans that produces oxygen and what things impact that?
Lastly, please link your post-doc, peer-reviewed source for "meh, 30% is not significant."
Thanks.
jeoeker531 t1_iudhs1j wrote
Trees don’t make 30% of oxygen either. The corn belt in the USA at its height of the year makes more oxygen then the Amazon. And nobodies cutting down all trees not even close. In fact there there are more trees in the US now then there were 100 years ago.
NemeshisuEM t1_iudix7l wrote
So how many new-growth trees equal to 1 old-growth one? Or are you going to tell me a 1' wide tree does the same work as a 10' wide one?
jeoeker531 t1_iudj5nh wrote
Why are we looking at what one individual tree does when we have data for all the trees? For millions of trees?
NemeshisuEM t1_iudjymh wrote
Because you stated "there are more trees now in the US than 100 years ago."
Commercial tree farming does not compare to an old-growth forest in numerous ways, so to compare apples to apples, we would need to know how the oxygen production of the two compare.
Got a link to a study doing that?
jeoeker531 t1_iudm7qy wrote
How much does the comparison of oxygen production matter when the vast majority of oxygen production isn’t been due to trees?
NemeshisuEM t1_iudo1gb wrote
Perhaps you should read up on this before asserting there is no problem.

Where did I say there wasn’t a problem? Can you find that for me?
jeoeker531 t1_iudjcnm wrote
The point is that trees are renewable resources and that even that 1’ wide tree will grow into the 10’ tree
NemeshisuEM t1_iudkfza wrote
But tree farms do not wait until the tree is mature to harvest it. That's like counting male calves as full head of cattle when in reality they get culled at a young age. Using that analogy, it seems disingenuous to compare a 50lb calf with a 2000lb steer. Yeah, each one has a head but one is not like the other.

Not quite.
You can "reuse" trees in a economic sense but that doesn't account for externalities.
You have to also realize that there is life under trees that you just can't replant.
Yes, you can replant trees in a sustainable way but alas, https://en.wikipedia.org/wiki/Pacific_Lumber_Company stuff like this happens.
jeoeker531 t1_iuhmfwx wrote
Yep, but you have to find specific examples of this not working. It can and does work… finding exceptions to the rule doesn’t mean it doesn’t work
r3b3l-tech t1_iuhpsjp wrote
So it's a little bit the same with cattle raising. You can do it sustainably, but it is not as economically viable(you make money, but not as much).
Sustainability is the exception. Companies just want profit.
That's why I am saying "Not quite". Yes, it's a viable option but when you look at all the realities, it is just not happening the way you might envision it.
jeoeker531 t1_iui40bf wrote
Yes companies just want profit, but in capitalism, for companies to make profit and remain competitive they have to have quality and adhere to some degree to what customers want. If people don’t like what a company is doing the company will lose money. Unfortunately when the government gets involved it corrupts and degrades the free market and capitalism
r3b3l-tech t1_iui99ec wrote
Companies can and do make money, with sustainable ways, in a capitalistic economy. There has just been a lot of deregulation going on, which makes the free market unfair.
I don't really understand what you mean with government involvement degrading the free market?
I am currently reading this book: https://www.goodreads.com/book/show/53167676-the-sustainable-economy?from_search=true&from_srp=true&qid=K4gGPesEM3&rank=2
If you are from the US I really recommend giving it a read. I have been very fascinated by it and the author provides lots of sources to verify the information!

Yes, but forests are better for storing Carbon. Oceans storing more Carbon results in carbonic acid formation, reducing marine pH, harming organisms that have shells like mussels, clams and corals. The issue isn’t just O2 in the atmosphere.

It's also important to note the importance of the ecosystem for the production of that oxygen. It's all connected. There are very good documentaries explaining this process in detail.
Also, nearly all oxygen produced by the Amazon rainforest is consumed by the forest.
