  1. PESTICIDES! Do you have an attitude? Dr. David Shetlar (the BugDoc) The Ohio State University/OARDC OSU Extension Columbus, OH

  2. Where did you get your values concerning pesticides? Parent(s)? Teacher(s)? Peers? Research into Subject??

  3. Watch out for Charged Words! Natural Synthetic Organic Chemical Biological Genetic Engineered Risk Safe Carcinogen Toxic Toxic

  4. The Numbers Games Measuring increases and decreases: Ex: 1 in 1,000,000 versus 2 in 1,000,000 “the incidence doubled” “the rate increased by 100%” “twice as many …..” Yet: 2 in 1,000,000 versus 1 in 1,000,000 “the rate decreased by 50%” “half as many …..”

  5. The Numbers Games Comparing Studies with Unequal Numbers: Ex: 12 of 400 wells in 1992 had pesticides. 10 of 100 wells in 1995 had pesticides. Therefore: 3% of wells in 1992 were “contaminated” while 10% of wells in 1995 were “contaminated” Newspaper headline: OVER A 300% INCREASE!

  6. Common Misconceptions (in my view) Pastoral View – “Older, simpler ways of life were better than today’s” Organic View – “Natural and/or organic products and materials are safer than synthetic.” No Risk in Banning Pesticides View – “There are no real risks in banning pesticides.” or “Life would be better without pesticides.”

  7. What are the Major World Human Diseases? • AIDS? • Cancer? • Diarrhea? • Malaria?
