It looked different from the formatting I did on my notes.
eSIM reduces plastic and shipping use.
Using older computers has to be weighed against the newly developed efficiencies in the latest cpus/gpus. Windows 11 is dropping computers that are like 4 years old. That is way too soon for perfectly good computers.
Synthetic cloths are used a lot currently so using microfibre filters is a stop gap measure until we have biodegradable cloths.
Since the commercial launch of SIM cards three decades ago, approximately 4.5 billion SIM cards are sold and shipped each year industry-wide, accounting for more than 560,000 tons of carbon dioxide and 18,000+ tons of plastic waste annually.
18,000,000 kg / 7,000,000,000 = 0.0025 kg per person on earth. 2.5g per person. Its not a big number at all.
Granted, not everyone has a phone or sim, so the number may be 2-4x higher, but we are talking about such a tiny amount of waste that its a rounding error in the scheme of things.
See, to me, those numbers just dont seem that bad in the scheme of things, annual medical waste in Victoria, Australia, is 3x that (Vic is a state of 7-8M people, we are pretty small). I bet the single use plastic shopping bags tossed annually dwarfs this by many orders of magnitude.
Many phones dont support eSIM yet, so an individual switching means throwing away an otherwise fine phone, and that doesnt seem worth it to save on 1 credit card sized peice of plastic.
Using windows is also massively wasteful, it spends probably more than half of the processor usage on analytics and tracking stuff. Linux or other free kernels are much better in terms of power usage, on old and new hardware
