GMOs, GMOs... leading producers of such, like DOW Chemical and Monsanto...yes, we should really be trusting such to not harm the food supply or hold it for ransom. Right.
Monsanto is still trying to claim Dioxin/Agent Orange doesn't harm humans, thus they have no responsibility for cleaning up the production sites in the southern USA or the results of that production in Vietnam.
They however, lost a class-action suit in WV this year (one of the production sites for AO amongst many other nasty chemicals).

These are not the people we should be allowing anywhere near this type of research, let alone be granting them patents on organisms.
I am all for doing it in an ethical manner, with reasonable testing, etc. Many of these corporations doing this though, have proven many, MANY times over that they are not in the least bit ethical, and love skipping corners to boost share prices.
