Definitely a good point if if doesn’t actually need to be plastic, i highly prefer natural materials overall. But thats not always practical.

I dont get the “someone elses problem” though. If the item is still perfectly usable then why would the next owner not also just want to use it? I personally value a hand me down that “served” my family for ages over “new thing”

If it is broken then it can get a new life by getting recycled.

Under current consumerism the pattern is that shit breaks and you buy it new, which causes us to psychologicly devalue the item (and thus materials) as it ages, i believe this is why so many plastics end up non recycled.

If items where durable, reliable, repairable. People will be more capable to perceive their value and be more concious about what happens to it after it breaks because losing it will hurt. Not quite like but somewhat similar to how we care about what happens to remains after death.

Also things being repairable increases the awareness of the materials because your working with them.
