I wouldn't say 'all' genetically modified foods.
Ever.
I'll check out these videos sometime. But with the addition of some 'franken foods' crap i saw on the playlist... makes me not want to watch it anyway.
Lets say you make a virus which makes corn grow 13 ears per plant instead of the average 3-5. How is this bad?
Higher crop yield per acre is... what exactly? The devil's own work?
This is the kind of crap the 'franken foods' people spout at you. (I know, I've questioned them.)
He actually explains why genetically modified food is bad in detail. It's the process in which they "inject" the wanted genetic code into the existing DNA to produce the desired affect. It can cause random mutations in the existing DNA, which sometimes can inhibit extraordinary protein release, which can sometimes cause the process for such things like cancer to evolve in the body.
There are other explainations that he does give to support his argument though, I personally thought the videos had a lot of merit, although I'll have to get more information to make a better informed decision.
