Surprise surprise... These businesses have rebranded themselves as biotech companies, but they are essentially chemical and pharmaceutical companies – many with a very dark history.  When it comes to a dark past though, Monsanto takes the cake, having produced the carcinogens Agent Orange, DDT, Dioxin and Lasso. It also produced rBGH (recombinant Bovine Growth Hormone), a hormone given to cows which has made them sick, and made humans who consume their milk sick too. However, Monsanto bribed the FDA to the tune of $1-2 million to get it legalized. Monsanto also took over the development of aspartame, an artificial sweetener with 92 reported health side effects, including irreversible brain damage and death.
