but truthfully, yes we are being exposed to greater amounts of pollution (and messengers are probably most at risk for this), but a healthy diet / a select few special foods and herbs (i'm thinking those asian sea vegetables that some vegans eat, and milk thistle) will do a good amount to counteract those effects. also your genetic / physiological makeup and how well your liver filters out toxins / poisons.
