Interesting that he mentions those things and not a word about hormones or metabolism...
maybe he sees the decline in metabolisms as a result of our culture and adressing it through diets doesn't fix the cause
i see it like this:
at the moment, mankind is opposing (human) nature: pollution, estrogens etc.
Why? Profit (peat agrees: "capital")
and nature seems to be opposing us because of it (diseases)
How do we deal with it? By hacking nature (through digital culture --> science --> modern medicine)
This has worked pretty well up to a certain point. Not only do we live longer, but quality of life also increased in comparison to medieval ages at least lol.
But it certainly seems that maybe for a few decades now our hacks aren't powerful enough anymore to reverse the negative effects of our opposition to nature. Investments in science (not only medicine) do not yield the same results as they did 100 years before. Paradigmatic changes are harder to come by, and even if something is found, it often remains unclear if it even makes our lives better at the end of the day. More complicated solutions come with more complicated complications.
Would we not be better of using all the money we put into science to understand and hack nature with diminishing returns to actually get our lives closer to nature instead? This could mean higher quality foods, less polution, greener cities, nature bound education, less emf, whatever you can think of. Instead of adressing the roots of problems (say cancer), we put billions into trying to hack them, so that we do not have to change our capitalistic system. This clearly does not work anymore. We have reached modernities endgame. If some guy cures cancer a couple hundreds of years from now, it won't matter anymore because we will be so far from what makes us human in the first place, and our planet will probably be ****88 as well. it's a big ******* joke what we have become. humans are weak as ****
