If we had a dime for every kooky, left-wing theory we've heard alleging some vast corporate conspiracy to exploit the treasures of the earth, destroy the environment and poison people with unknown carcinogens all while buying off politicians to cover their tracks, we would be rich.  The problem, of course, is that sometimes the kooky conspiracy theories prove to be completely accurate.   

Lets take the case of the $60 billion ag-chemicals powerhouse, Monsanto,  and their controversial herbicide, Roundup as an example.  For those who aren't familiar, Roundup Ready is Monsanto's blockbuster weedkiller, credited with transforming U.S. agriculture, with a majority of farm production now using genetically modified seeds resistant to the chemical. 

For years the company has assured farmers that their weed killing product was absolutely safe to use.  As proof, Monsanto touted the approval of the chemical by the Environmental Protection Agency (EPA).
