In 2017 I bought a ThinkPad with a hidpi screen, which I knew would give me trouble with Linux. Fortunately the Fedora 26 beta had just been released and was using Wayland by default (I wasn’t very Linux savvy to do it myself yet). I’ve been using Wayland on Fedora ever since without issue.
From what I’ve read PLA is only biodegradable under very specific conditions. I looked into it and you have to send it to a recycling center designed for PLA and its expensive to do so. I would assume microplastics would still be present too. Even though it can be sourced from plant matter its still plastic.
