Agreed. We already have BT resistance where BT is used like a conventional
insecticide -- e.g. diamondback moth in cabbage. There is also evidence for
European corn borer resistance to BT.
My memory is that when the BT toxin genes were first cloned into plants it
was meant more to be a test of the technology of genetic engineering than a
prelude to mass marketing BT genes. Right now it looks more like an
experiment in real life. I am not sure that this is all bad. With every
technology you have to start some place, and in this case it looks like BT
will be sacrificed to get the real world data.
There are many other insect pathogens out there, most not so well known
outside the realms of insect pathologists and biocontrol specialists. I
think that the tradeoff for the loss of BT needs to be funding to develop
these other microbial alternatives. Perhaps some sort of set-aside scheme
where the BT-replacements will not be used for genetic engineering. Thus,
preserving a microbial reserve for farmers.
The trick will be to get the farmers to use these other microbials wisely.
Even among organic farmers, too many that I have met use microbials like BT
and other natural products in the same way that many farmers use chemical
pesticides. i.e. they spray far too much, thinking that because it is
organically approved it can be used three times per week.
<2. I'd be interested in hearing Peter Drucker's thoughts on this,

The fulltext of the Drucker interview article, as well as the Monsanto
biotech article can be found on the Forbes web site or the Forbes
Compuserve site [GO FORBES]. It is the 10 March 1997 issue. As I reread the
article, Drucker seems to be referring more to the population trend in the
industrialized world, e.g. Europe, Japan. I don't what his thoughts are on
the so-called developing countries.
According to Forbes magazine, Drucker says: "The population is already
peaking. It's beginning to decline. By the end of the next century there
will be no Italians left. Very few Spaniards -- and very few
Japanese...These are official forecasts, not mine. The birthrate is not
increasing. The reproductive rate is down to almost 1 in southern Europe
and about 1.5 in Japan...There won't be enough people to work. There'll
only be older people. There won't be enough producers. The main reason for
the decline in births is the enormous burden on people of working age
supporting older people in retirement who are hale and hearty." BTW,
Drucker is 87 years old and still active.
