🔴 🌍 **Global gridded population datasets systematically underrepresent rural population**

_“We find large discrepancies between the examined datasets, and, without exception, significant negative biases of −53%, −65%, −67%, −68%, and −84% for WorldPop, GWP, GRUMP, LandScan, and GHS-POP, respectively. This implies that rural population is, even in the most accurate dataset, underestimated by half compared to reported figures.”_

Mass extinction may not be as we think. Palaeontologists and scientists are now thinking that mass extinction did not affect the land as much as it affected the seas. Meaning that pockets of ecosystems continued creating stability of the food chain and assisting terrestial animals.
