You have probably heard of Monsanto, the leader of GMO engineering. The company is infamous for developing the Orange Agent used by the US Army during the Vietnam War and other cancer inducing products such as Round-up and PCB. To sum it up, a company with a past full of lies and death for money sake.
In case you would like to discover more about this multinational, I strongly recommend you to watch the documentary 'The World According to Monsanto' made by a French journalist, Marie-Monique Robin. This shows the urgency of closely monitoring the company activities and counter them when their actions endangers the environment.
