If you’re looking for a case made with sustainable materials you can get a Pela Case or Apple FineWoven (I have a FineWoven case and it’s held up really well). The thing with either of those is that I don’t think they’ll last 4-5 years.

I think there is a strong argument to be made for a durable case because reducing your consumption is also eco-friendly. Additionally buying something strong and durable reduces the likelihood that you’ll have to replace your phone if you drop it! Strong and durable category you can consider Caudabe (from my experience, really solid cases).

Some people just want a MacBook Air with a better screen and more ports and they are willing to pay a premium for it. That’s all there is to it.
