My problem with these examples is that I see nothing about them that
is unique to transgenic technology.  Similar sorts of problems are
raised all the time by "conventional" technologies, including very
ancient ones like selective breeding.  An analogue to 1 is simply
overuse of pesticides (or antibiotics for that matter), which can
render them worthless in the way you describe.  And 2 in no way
raises ethical issues different from, say, starting a palm oil
industry in Key West, possibly after selective breeding of oil
palms to produce strains that give high yields there.

Indeed, I doubt that there _are_ any ethical issues which depend
_specifically_ on agricultural use of biotechnology as opposed
to agricultural technologies in general.
