The obsession over the carbon footprint is that it is pure waste (like sticking a gigantic space heater in the middle of nowhere and running it 24/7)

It has an efficiency of approx 0%.

And as it gets more successful it gets less efficient and wastes more energy.

And there is no incentive to reduce that energy usage (Facebook would save money if they could make their algorithms more green, for example so they may pay people to look into that).

Bitcoin has to pollute, for the security of the network.

Also there is the manufacture of disposable single purpose hardware for the mining of bitcoin and it’s environmental impact.
