Main issue I see with this is:
you say yes:
multinationals start genmodding everything possible
they tag their own genmods for trademark/copyright/patent issues(no I won't use the completly undefined intellectual property meaning, since they are 3 distinct sections not a single one)
they then release viruses to kill off anything not gentagged by them... And there you go...
The end of natural life... And a new master-slave system is born.
(taken from a book(though sadly can't recall the title).
So yes genmodding should be outlawed.
How to make farmers more profitable? kill off their subsidies for growing unprofitable
crop etc... Have a bit of a mix in with the companies that buy from farmers to make it
an even playing field. Free market is an illusion... If you have a free market you get
mono- or duopolys since that's what a fully Free market strives for. A proper market that
benefits all is one that is regulated by authorities(or one). Giving farmers more subsidies
for growing unprofitable crop makes no business sense at all. Forcing just one side to
do something won't make a difference. This has to be tackled in all areas at once.
