The emissions add up: Ammonia production consumes about 2% of the world's energy and generates 1% of its CO2.

2% not 20%

> Bitcoin currently consumes around 110 Terawatt Hours per year — 0.55% of global electricity production

Ok it’s in vicinity of 5 percent and not 20 percent, still quite large, And ammonia used for what ? Fertiliser?

These sort of stats are useless without cost benefit analyses.

Suppose that 0.00015% of all ammonia production goes to chemical weapons manufacturing.

Boom, analysis complete.

Do you think that making fertilizer that literally feeds the world is comparable to bitcoin?

Your comment is just whataboutism:

You point out other ways to improve our energy consumption to avoid touching to your beloved crypto mining. While it could be both.
