Most of the mining is done in countries like Iceland where electricity is cheap and clean (geo-thermal).
So the pollution angle doesn't come in at all.
I do not think even mining is done in some other countries that banning of mining is possible. Because people mine with their own cost of electricity. May be government push for new regulations for standard emission control rules for ASIC miners to reduce the heat generations.
in the meanwhile we all know that carbon emission is not doing shit to the climate and the global warming is all a big scam to fill the pockets of big corporations.
And granting more power to the government so they can use it for wars and spying on us.
