GMO’s Jeremy Grantham is back to his Malthusian best. I should remind you that he said almost exactly the same thing in 2010 before an enormous commodities bust.
I disagree on decarbonisation being “spectacularly resource intensive”. In fact, the impact on consumption of extractive commodities is mild as recycling booms too. China is also about to turn much less commodity-intensive over decades.
That said, infinite growth is an impossibility so Grantham has good point.
