> if spread across croplands globally

That’s a big if! Reminds me of “the market for comics is $32 billion a year. If NFTs can capture just 1% of the market that’s $320 million per year.”

Also what are the CO2 emissions of transporting all these rocks??

No kidding. I’m struggling to think of any technology or technique that’s ubiquitous globally. Not to mention the labor and emissions required to harvest, transport and spread heavy rock across even a small percentage of fields.
