  • I shall tell you the story of FrankenPod. One iPod had a broken hard drive; one had a tear in the connector to the screen. I managed to reassemble a funtioning iPod from the pieces of each. Eventually, though, it became too onorous to find the old-style iPod charging cables, so I had to move on. But I do miss FrankenPod.








  • Except it doesn’t hold up in the elements all that well, though (at least in a form that is still usable, the plastic is still there, just in little pieces and/or without the desired structural integrity). Plastics degrade when exposed to sunlight and oxygen (photo-oxidation). Combine that with mechanical action of waves, and now you have a bunch of little plastic bits floating in the ocean that are even harder to clean up (but easier for the bacteria to eat!). A glass or metal bottle will hold up much better than a plastic one, over a long enough time period.

    But they even break down when exposed to temperature cycling and mechanical stress over long periods of time. I’m sure you’ve also noticed old plastic food containers, get harder and harder to clean and start getting cloudy: that’s the plastic breaking down and micro-fissures appearing on the surface, thanks to repeated exposure to dishwashers, freezers, and still-hot leftovers. Once again, a glass dish is gonna hold up much better.

    They have to use special additives for plastics intended for long-term outdoor use (the additives are like sunscreen for plastic, they absorb the UV so that the plastic doesn’t) to combat these reaction pathways. And I’d bet money that if plastic-eating bacteria end up becoming a problem, there will be additives we can use to discourage them for appropriate applications.

    But you’ll notice that in the case of plastic in landfills, there’s no UV light from the sun, basically no oxygen, and any mechanical stress or temperature cycling isn’t enough for fast breakdown of the plastic polymers. These conditions are also very different from, say, your kitchen counter or hospital storage rooms. If the plastic-eating bacteria prefers the landfill habitat (or literally cannot thrive in any other environment – which is not an uncommon phenomenon; in the article, they mention difficulties culturing bacteria for study in a lab environment), then we have a perfect tool for breaking down landfill plastics that won’t impact in the slightest the plastics things we want to keep. Similarly, the kind of bacteria that could be useful for ridding us of fishing lines and nets floating around in the ocean would most likely not be well suited for non-aquatic environments.






  • Absolutely. I did not mean to imply that small daily-life changes are all that is necessary, just that we shouldn’t count them as useless just because they are small impact. At the very least, it is a tool i use to keep climate-change-induced depression and anxiety at bay enough to make “real action” something i’m mentally capable of.

    Yes, but making changes in my own life (as small as they may be in the grand scheme of things) helps me feel a little less depressed about the whole thing. So many of the most impactful changes are outside of my control. Yes, i can, to some extent, make my voice heard and push for policy changes, and I can refuse, to some extent, to purchase from or invest in companies that are the biggest polluters and carbon-users. But I’m not a CEO of a multinational oil and gas conglomerate, nor am I in charge of making policy decisions for the country (hell, I live in a very red state, so my vote essentially doesn’t count, outside of local elections).

    But I do have the power to set an example. It is always good to make changes that you can, even if it’s comparitively negligible. I think if everyone made the effort to live more sustainably, the people that actually have the power to make big changes may feel more pressure to do something (people asking “if i can do it, why can’t they” when voting or making purchases or investments could have a big effect if we all did it together). It would also help show the greenwashing that a lot of companies engage in as a facade (people that actually know what it takes to reduce their carbon footprint would be more aware of what does and doesn’t have an impact). Possibly… Maybe we’re all screwed and there’s nothing we can do about it and civilization as we know it will come crashing down around us. But I think hope is a good thing to hold on to in the meantime, and doing what I can in my own life gives me hope.






  • I really enjoyed playing Hades, but I just didn’t have the skills or patience to progress at the pace I wanted. So (after realizing that being prideful about difficulty settings in my hobbies that i do to have fun is a dumb way to live), I turned on God Mode. You get extra stacks of damage resistance every time you die, capping at like 80% or something, and you can turn it on and off as needed. After that, I was having so much more fun, and the rate of progression was much better for me. I felt like I was finally playing the game that everyone else was loving so much.
