Pollution

I have briefly perused your great website. I am looking forward to reading it in-depth. This probably sounds silly. I have not asked anyone else this question. 
I feel very inhibited by the pollution in the Northeast US. I have chronic sinusitis and definitely need to do breathing, but I feel like I am also taking in more pollutants (indoor and out)! Can you show me the flaw in my thinking here? 
Thanks for the information and support.

From Mike:
No flaw. You are in a classic double bind. Wanting to breathe better and worried about what it is that you are breathing. Feed it, develop it and protect it. If it is THAT bad, go to work to change the environment or LEAVE it. The latter is probably the most direct and effective. Antioxidants are also a way to offset
