I'm a bit active about sustainability, renewables, cleantech, recycling, reducing use, re-using, food politics, climate change politics, actually doing things ourselves to turn the tide, speeding takeup of EVs and renewable energy, and basically getting us out of the hole we're currently in. To do that I've several websites with useful and thoughtful content, several blogs each with a fairly specific topic among the above, I have 3D printables files for things that convert waste plastic into useful and valuable new things or are the machine that you can build to do the converting. Most end up here for a token fee, and are also on public repositories. Any item I post here for the token fee, I'll generally include a link to the free version on public repositories as well.
