Todhunter draws material from scientists to argue that science has not arrived at agreement on this issue. Meanwhile agricultural corporations using GMO technology keep maintaining that the technology is perfectly safe. Of course, the technology is creating vast amounts of wealth for the owners of these corporations.
As I've argued before, capitalists pursue wealth because of its easy convertibility into power over others which is its main objective. The pursuit of wealth is mostly a means to such power.
Another unique feature of the capitalist system is mostly a great secret: the nature of capitalist class power is that it is very indirect so that it usually functions without the use of coercive physical force. Instead capitalists rely more on "market forces". To be sure, ruling capitalist classes have installed powerful coercive forces (militarized police forces, a huge military-industrial complex producing all sorts of lethal weapons, a huge prison system, etc) whenever market forces cannot accomplish their aims. With their ownership/control of media, they are also able to spread lies about their operations whenever the truth gets in their way. Todhunter is a media activist that is putting the lie to messages amplified by corporate media that GMO foods have been shown by scientists to pose no significant hazards to the health of humans or the environment.
The industry's claim that there is a 'scientific consensus' on the safety of GMOs is about as bogus as its claim that this technology is required to 'feed the world'. That too is a deception....
