Major choices with seeds are, GMO, hybrid and heirloom. It is about market share between those seed types. Most, not all but most, everything I've read so far on the anti-GMO/Mansanto is hype to gain market share. Doesn't matter if someone says GMOs are bad or patents on seeds will be bad or Mansanto will have a monopoly. It is all about market share! Getting rid of GMOs or keeping them but not patenting them or getting rid of Mansanto will not stop corporations from making money.Off topic for this thread but it is possible to hold conflicting ideals, I certainly do. As a generalisation I myself am anti capitalist but I am a realist and pragmatic about my views. I don't like the philosophy of the corporations (i.e. making money) but I accept it as a fact and move on.
Anyway, I think you are simplifying the sides in the GM debate. To be anti GM does not mean you are organic although it seems most of the arguments come from organic farmers. I do have a general anti-GM stance (yeah it may not seem it) but I am far from being totally pro-organic as I believe chemicals do have a place in agriculture.
Sorry, reading that back it all sounds like total pants.
I just need more than, they make you sign a contract to be worried. Farmers are smart, they have lawyers, they talk to other farmers. If these contracts will end up hurting farmers they will know and not sign them.
