Well, wool is particularly bad, emitting way more greenhouse gases than most other textiles for equivalent fabric output. And sheep farming has quite a shocking impact on biodiversity. https://www.vox.com/future-perfect/24008053/wool-marketing-e...

This is interesting, thank you for sharing. Would you happen to know where the data for this table comes from? https://platform.vox.com/wp-content/uploads/sites/2/chorus/u...

The article links to this study, and the diagrams seem to be adaptations of figure 4. https://www.dropbox.com/scl/fi/4tyqsnuof548f1wio7dgf/Factors...

Edit: I don’t think cotton is the best replacement. I’m no expert, but I think hemp, flax, and tencel are the “best” replacements in terms of sustainability.

These are two of the coolest and most fascinating comments I’ve read. Idk if you are a professional …. Astrogeologist?? or just a really smart person but I would like to subscribe to your newsletter for sure. Thanks for sharing this!

No, I am an electronics engineer. However, I happened to have some relationships with a few professional astronomers, because my father had worked for many years in an astronomical observatory, and I keep following the research publications in this domain. There are a few such facts about the history and the diversity of the world in which we live that deserve to be known by more people.

You have a talent for writing in a way that's both approachable and full of information. It comes across as super knowledgeable without losing that wonderful sense of childlike curiosity, which I think makes it particularly approachable or even inviting. It reminded me of PBS Space Time.

It's an artful balance that is so rare—especially online—that I think some of us just savor it when we do find it. I actually went through your older comments (sorry) just to keep reading what you had to say...

flared yourself. just use another DNS. edit: https://news.ycombinator.com/item?id=38373137 root cause: https://hn.algolia.com/?q=cloudflare+archive

I don't use anyone's DNS. I just think it's ridiculous for an archive to be behind crimeflare's MITM-as-a-service.

Then it would be interesting to see if these specific problems still persist if would use another DNS. Since they are typical for using cf. Maybe your upstream does, without you having noticed so far?

Cotton is a terrible replacement for cold/wet. Not sure any of those other are great though. Don't know much about tencel but the manufacturer's advertising certainly doesn't frame it as a cold/wet clothing material.

I would like to know how do you not use anyone's DNS.
