  • A lot of the trees being cut down are old growth forests, there are nearly no old growth forests left on the whole continent and some animals specifically need old forests with their diversity of species and with different ages of trees throughout. Things grow back differently when you clear cut a section than when an old tree died and falls here and there or is harvested sparingly without destroying the surrounding trees and underbrush, so the lack of selectivity when harvesting is also harmful. Cutting down everything and replanting one species that grows ok in a clear cut area doesn’t restore the forest. Look at longleaf pine forests, for example. Nearly the entire southern US used to be longleaf pine and now it only exists in 3% of its former range. The southern US is still covered in pine, but it mostly got replaced with loblolly pines. You can replant some trees, but you can’t replant a whole complex forest ecosystem, and many of the trees people replant are ones they think they can personally profit from like the fast growing loblolly pines rather than slow growing species that need special care and land management practices to maintain good growing conditions.






  • All of the big hotel chains use the same plastic key cards that are credit card sized, they are durable and can be reused many times but also cheap enough to not fret over them if a customer forgets to return it before leaving. As a former aircraft maintainer myself, I don’t personally think it would be an issue if Boeing or its contractor ordered a bunch of standard hotel card blanks for seal testing, but if they were meant to use that as their test device it should be documented , there should be a part number for that card and authorized suppliers, and there should be a specific procedure to follow when using them. The article mentions the lack of documentation, so this was probably an unauthorized improvisation on the fly. I doubt these were being used to measure a specific tolerance, this case was probably something stupid like “the cabin pressurization check failed after we replaced the door, let’s poke a card along the seal to find where the gap is and squeeze extra sealant in that spot.” My specialty was avionics though, so I will admit I don’t really know much about the pressurization checks and seals, I was always at the plane for some other work whenever I encountered them.
