I've found that its just a waste of time. I lived with a dumb roommate that was in your face about her Organic eating habits, she was spending $60-100 more on Groceries than I was. I buy my veggies and fruits from a farmers market and I drink Soy Milk because of my lactose intolerance.. she is no more healthy than I am.
Organic food is just another big fad that sucks people into paying more for stuff.
Just because food isnt "Organic" doesnt mean there are harmful chemicals and pesticides in it. If you are that paranoid, research the companies you get your food from, find out how it is raised/harvested and purchase accordingly.
With that said, I don't purchase meat from Tyson or Purdue cause I know how terribly they treat their animals. If at all possible, I buy from companies that are free range or from farmers at the market who bring the animals and butcher them for you after you purchase...
