This was a screenshot I took months ago while watching a Geology Hub upload on YT. It was a lightbulb moment for my understanding of mass extinction events, (the largest was 250ma). I’ve referenced this multiple times, so thought I might share. Perhaps you find it as interesting as I do.
I often wonder about this. Is the increase in CO2 making us dumber?
I’m certain the micro plastics and forever chemicals are messing with us majorly. It’s causing more than just higher cancer rates, but all these things are hard to tease out, especially since global we’re all being exposed to so many new poisons over the same time periods. It’s in the rain, the soil, the oceans, and everywhere else
It all just makes me think - how much potential are we each losing to subtle effects of pollution?
I’d think that the aerosolized lead from leaded gasoline did far worse than any plastic or change in CO₂. There’s still lots of volatile pollutants, like CO and hexavalent-anything out there.
