Is it possible to protect your body from air and water pollution in a big city like Chicago? I have thought of water filters, air filters, juicing vegetables, mostly raw food diet, and occasional fasts to help keep toxins out of my body. Also certain house plants. Does anyone know what impact these protection measures would have? Also does anyone have any other ideas? I'm thinking about moving to a high rise apartment building (maybe Marina City) downtown Chicago for about a year to try it out. I've had some pretty serious health problems but feeling better lately because of eating healthy and taking a medicine. That's why I'm concerned.
Thanks

(side note - Japan is very polluted and at the top in life expectancy)
