Environmental friendly hardware addons

Stuff like coca-cola leads to production of million times as much plastic. I believe that's an offtopic. MSX people do not ruin Earth, big companies do - remember teflon used in tefal frying pans, which was produced with use of perfluorooctonoic acid, or PFOA - a carcinogen, hormone disruptor, and reproductive toxin, which is also highly persistent, which means once it enters the environment it does not leave. Compare that pollution with a few thousend of newcly produced cartridges. That's only one example out of tons. But not much of people stops consuming drinks from plastic bottles because of the environment. Sad but true

Thank you for replies,
Of course I understand the pollution of MSX stuff compared to Danone or Nestlé, is just neglectable.
But was another approach to introduce an idea.

Having a modular cartridge, just attach another hardware extension.
It is similar like cartridge slot extender, however using the, for example, 40 pin GPIO header of Raspberry Pi, and attaching boards and boards without using additional cartridge slots.

But over thinking this idea, maybe good solution 30 something years ago.
Because lots of hardware extensions should be redesigned, etc, etc.

Thank you for all replies, and support Ukraine!
