EX,

Monsanto won't warrantee the yields of the round up ready crops if round up type generics are used. Try getting Holden to warrantee when non Holden parts are used.

Considering that seed is produced separately from normal crops, whether GM or other wise, a farmer changing to non GM crops is unlikely to grow more than a tiny fraction of GM. Likewise Monsanto won't prosecute for tiny percentages.

The cases in Canada prosecuted had percentages so high that "accidental pollination" was possible but extremely unlikely.

As patents expire, any registered patent from a 3rd world plant will become available to all with all its research within a generation.

And in spite of all of the negative GM press the farmers are prepared to pay the premium to plant it. The increase in profits far outweighs the negatives.

Once again, everyone has the choice not to use it.
