Like it or don't Ehrlich was right back in 1968. He was just off, a bit, on the timing due almost wholly to the exponential growth in petrochemical fertilizers. I don't recall where I read it, and it was a lot of years ago, but one large corn farmer put it this way: "the soil is just there to hold up the plants". IOW, the soil has become empty of nutrients and the only way to grow crops, at scale, is with these petrochemical fertilizers.
Now comes more. It's been known for some decades that subsistence Brazilians have relied on slash and burn farming. Well, the chickens have come home to roost. Of course, the dictators of the world will claim that this is all woke science lies.
Less rainfall doesn't just mean less water for plants and animals. As the forest becomes drier, it becomes more prone to wildfires, which, in turn, eliminate more trees. The region has been plagued by slash-and-burn agriculture, in which fires are used to clear big tracts of land for ranching and farming. Sometimes, these fires burn out of control.Here's the dire truth: the kids of today's 20-somethings may be able to live, but their kids? Not so much. Ole Mother Earth has a finite carrying capacity. Some estimate we're already there A steady reduction in population is the only way out. A plague or nucular war might end up being the only way out. The former did nicely in Europe long ago, and the latter in a couple of towns in Japan more recently. And the notion that most of the population can live the 90210 lifestyle?
There are a few ground truths in econ. The groundest of them all is that the individual's craving for consumption is infinite. What does that mean, in this day and age? That exponential population growth and infinite consumption are fatal. It also means, should we be wise, that economies can keep spewing ever more widgets to a population that is fixed, or even slowly declining. There's a reason that the pharma world loves them their Seniors: infinite demand. Of course, it was the Damn Gummint that handed pharma the Mother Lode by requiring Medicare to cover all drugs (very nearly, anyway). Yeeha!!!
