- Weaker o-zone layer
- Vaccines
- Climate change
- Rise in c-sections and pain medication for labouring women
- Diets (gluten free, dairy free, vegetarian, etc.) where there is limited medical necessity or study that proves their effectiveness
- Increased pollutants
- Blanket use of electricity and/or batteries (constant aural stimulation, if nothing else)
- Processed foods and the need to find ways to speed reproduction to please the masses
- Use of factory-made hygiene/beauty/cleaning products, not all of which are regulated
- Plastics created and used everywhere for nearly everything
- The average person works longer hours and gets less rest
- Greater use of medications where a change in lifestyle could be the better way to solve the problem
- Use of machines (planes, trains, cars, etc.) for transportation
- Tanning and hairless bodies became a beauty standard
- Daily showering is expected as the norm
- Smoking and drugs became cool
These are just some things I came up with; there are countless others. I think it's worth considering. There have been a lot of changes, and we should be careful when blaming one element of change for problems we are encountering in excess without significant proof of their fault.
