I feel the same in a way too and wish much more land with that old growth was still around for everyone to see what it was like and experience the ancient trees and rest of the ecosystems before human damage
would concrete be preferable? was it unused or used as a rich mans palace. I kinda assume it was like hotel as most things like this end up in that kinda way.
The problem with concrete is that its usage emits a lot of CO2 and it’s not really recyclable whereas wood, as long as you plant new trees, is roughly CO2 neutral and easy to recycle.
Last I heard concrete was recycled by simply using the rubble as stones to throw into new concrete. Usually sorted by size to adhere to certain regulations or something but never without new concrete. Can you give me a source for anything else?
heard about a net-negative carbon concrete recently, havent bothered to look into to see whether they’re legit or using some carbon-credits bullshit to pretend to be net-negative.
Their website doesn’t really provide any details. Looking at some older articles (2016), it looks like MgO cement was often made with coal and the final product was not CO2 negative if looking at full lifecycle. Pratana launch in 2021, so maybe feedstocks changed.
Regardless, it seems like a somewhat new product, so adoption would be slow while confirming all performative characteristics for engineering compared to well documented Portland cement.
Yes. The trees you use to build actually store carbon while they’re still the building. However, as buildings aren’t actively taken out of the ecosystem, their carbon will eventually be set free as well, because they burn down or are left to rot or something, so these buildings aren’t net negative unless you later take care of the raw materials and take them out of the cycle. If you don’t, it’s roughly a zero sum game (roughly because your work usually emits done CO2 as well, so it’s not completely 0).
I’m reasonably sure that a timber building is probably still better than a concrete one, for the same capabilities, when total environmental impact is measured.
My objection is that this is clearly built from massive old growth trees. These may technically be renewable compared to oil but they really aren’t in practicality since it takes multiple lifetimes for trees to grow that large. I don’t have an issue with using younger trees and replacing them but once you’ve seen an old growth forest irl, you realize how tragic it is that most of them were cut down.
Ironic, given that you are ignoring the historical context of this photo to make a weak point. When a tree falls, it contributes back to the ecosystem throughout its death and decay. The land wasn’t needed for anything beyond the standard manifest destiny development of the hotel. These trees were specifically cut down for their lumber, they would not have been wasted because they wouldn’t have been felled otherwise. Moreover this was long before anyone was planning long term sustainability goals. This was in no way sustainable removal of old growth.
The amount of trees killed to build this monstrosity is infuriating.

Giant ancient trees,
Stood millions of years before,
Homo sapiens
Exactly

Seems not the bad to be honest. But ive only read the wikipedia article. I dunno much about this center
https://en.wikipedia.org/wiki/World_Forestry_Center
Local Portland resident, the center is very well run and right next to the Oregon Zoo.
It wouldnt have burned down. Checkmate.
I don’t understand the problem with concrete. What are we supposed to build things out of?

Concrete is extremely recyclable. Like, more than Aluminum even.

How is that not recycling?
The issue is that you still need lots of new concrete this way. You don’t end up with a circle of your resources.
It’s not a bad idea but it isn’t climate neutral unless you come up with a climate neutral way to mix new concrete.
also iirc it requires special beach sand, which means that beaches around the world are being harvested.
Angular sand, which supply of is environmentally limited leading to black markets: https://www.scientificamerican.com/article/sand-mafias-are-plundering-the-earth/
Obligatory reminder that tree plantations aren’t equal to old-growth forest. So the latter needs to be left alone.

Burning trees is CO2 neutral because trees are part of the active carbon cycle (you’re not digging it up from deep underground to burn).
Yes. The trees you use to build actually store carbon while they’re still the building.

👍

Of course it is. By miles. I didn’t mean to suggest anything else.
I think we’re vigorously agreeing :-)
Where does the CO2 come from?
Mostly the cement.
Seems like it would be easy to capture, just no one makes the concrete companies do it.
Marble. Greek this shit up
it has a carbon footprint and building from wood sequestors it for a time. Not saying its necessarily better but its not a bad building material.
Cross-laminated timber and bricks.
Which I’m sure are not appropriate in many cases but it’s what I could think of 🤷🏼
bricks - fired clay?
Ye, good ol’ bricks.
The amount of trees killed for the log cabin part is 54, but I can’t find a source for the amount of lumber in the framed upper segment.
As opposed to what other renewable building material?

So?
What happens when a tree reaches the end of its life cycle? It falls down and maybe damages other trees as well.
There’s nothing wrong with sustainable removal of old growth.
Or the land was needed for whatever was being built and they used the trees for this instead of wasting them.
You’re complaining over nothing with no context.
Dead trees are wildlife habitat.
