So, are fruits produced by DNA tampering no different from fruits that
have formed from natural mutational changes? And is there any reason why
such fruits or vegatables that have to be propagated by other means are
less nutritious or contain any more toxins, etc. Do you think the
increased sugar in some of these fruits is natural sugar? I think I may
be on the wrong track thinking that genetically altered fruits might have
altered forms of sugar. Same question for Beefalo which I believe was the
resuslt of man's tinkering with the mating of buffalo and cattle? Isn't
human selection natural selection?
BTW, I believe I was wrong about those hut-shaped coconuts. The lady in
Chinatown said the hut-shaped exterior is natural. I see no sign of
tampering and the milk doesn't taste like refined sugar or set up any
cravings for more.
My best, Ellie
