Nah I think all the microplastics, metals, food preservatives and other various pollutants are the cause for all the mental health problems many suffer from. Ppl usually brush these things off because they think "well everyone else is getting contaminated and they're all fine! (They aren't*) so it must be some unique problem with me!" But they're wrong, these pollutants fucking us all up need to get more attention because ppl civilizations hundreds of years ago pre-industrialized society didn't have all these problems.
Even primitive tribes excluded from modern industrialized society in today's time that have been studied don't have half of the health issues as us "1st" worlders
