    The main contributing factor to the recent increase in malocclusion is widely considered to be due to a sharp reduction in chewing stress, especially during critical periods of craniofacial growth.[10][1] Experiments done on non-human subjects have shown that induced nasal blockages and/or dietary changes earlier in life lead to maladaptive morphological change in their jaws, intended to simulate what we are observing globally in human children.[4] Significant craniofacial changes due to diet have even been experimentally shown in pigs during development; researchers fed groups either a hard-consistency diet or a soft-consistency diet, for eight months in total.[11] Drastic differences in jaw and facial musculature, facial structure, and tooth-crowding were observed; researchers directly related the findings to what we are observing more in human populations.[11]

    so too much damn baby food?













  • Sure, in the long run humanity will adapt and survive, but we will definitely have problems to address in the near-ish term like the next 100 years or so. the main problem is causing an inverted age structure. it means there are fewer people paying taxes, and there will be fewer people around to take care of the older generations when they are elderly. Many developed nations are experiencing this and worried about it.

    and ‘sex’ isn’t the issue; with modern education, contraception, etc you have to convince families to want to have kids. It doesn’t seem to be any one particular thing holding people back either, so it’s not as simple as subsidizing childcare or making families more financially secure. Countries in europe give lots of financial assistance to raise kids, but their birth rates are still much lower than replacement levels.
