The early part of this video provides an excellent summary of some of the key elements regarding Monsanto and Nestle. In the case of Monsanto, it mentions, amongst other things:
* Their history with DDT and Agent Orange
* The doctrine of substantial equivalence, which is the wide open barn door through which GMO product flows unrestricted into the American food chain (and any attempts to label foods containing GMO products in the US are vigorously resisted by Monsanto and others)
* The revolving door between Monsanto and the FDA and other so-called regulators (this practice is not limited to Monsanto nor the FDA)
Some good journalism here, in my opinion.
