I think that it seems pretty obvious that while so many chronic illnesses skyrocket, and we have thousands of novel chemicals, and disease skyrocketing faster than major genetic changes could happen, that its likely most chronic illness will be discovered to be the result of pollution or chemicals. this is the contention of robert naviaux

I would not deny the involvement of man-made chemicals in triggering or worsening disease.
Indeed, just prior to catching my ME/CFS-triggering virus, I had a severe chronic exposure to organophosphate pesticides, after a large amount was (unbeknown to me) spilt in my home, where there is no wind or rain to disperse it, so it became a chronic exposure. The exposure was severe enough to cause some major effects in my gonads (which I will not go into!), as well as causing terrible psychological symptoms.
The psychological symptoms triggered by major pesticide exposure are dire: lots of farmers in India are constantly committing suicide, and there is a pesticide link to this (these farmers are not educated to understand that pesticides are very nasty chemicals, and in India they don't have the right protective equipment anyway).
So I am appreciative of the problems caused by toxic chemicals.
However, when you speak to the average person, many feel that environmental chemicals are the culprits behind much of disease. And many people go in for detox diets and such like, in the hope of removing chemicals from their body. You hear people say "this weekend I am not going out partying, I am going to do a detox". So in the common mythology of the people, chemicals are the villains.
However, very, very few people are aware of the enormous potential involvement of pathogens in ill-health. I certainly was not. Pathogens are just not something that appears on people's radar.
Greenpeace and similar organizations will raise awareness of chemicals in our clothes, chemicals in the air, chemicals in our water, etc. But they are totally silent on the issue of pathogens.
And this I see as a major disaster, because if people are not even aware of the problem — if they are oblivious to the fact that pathogens may well be causing untold misery and suffering via triggering chronic disease — then how are we going to even begin to address the problem? Pathogens are the invisible enemy that nobody suspects.
So the issue of chemical toxins is well served by activist groups, as well as by science itself. The issue of pathogens is barely addressed at all. The human race is asleep on this issue.
