Incororating resistance to Roundup & now a couple of other herbicides (beca=
use weeds also becoming resistant) in GMO crops has one huge effect on wild=
life that I don't see discussed much or at all: the complete obliteration o=
f weedy species over massive areas, not seen much in NS but go to Que and O=
nt where field after large field of GMO soybean, maize and cannola are grow=
n, and they are virtually dead except for the crops; even after the crops a=
re taken off they remain free of weedy species. Under traditional managemen=
t, weeds were set back by tillage to allow crop to get established, then a =
diversity of weedy species grow up in the understory, flowering and providi=
ng food for pollinators, seeds for wildlife.. and after the crop is taken o=
ff, groundcover. No more so. The farmers like the GMO crops because of the =
simplified management, but with selection of appropriate cultivars, some me=
chanical management, reducing some types of tillage...weeds can be controll=
ed without eliminating them and our farm fields can be more supportive of w=
ildlife.=C2=A0
Glyphosate is toxic to plants and bacteria, so has huge effects on the micr=
obiotia also..

David,no confusion here. Listserve focus is on nature not human safety. Atr=
azine article deals with human safety concerns not biodiversity.If we want =
to take a stand on pesticides it would be for their biodiversity implicatio=
ns of which there are tons. Roundup is an example but there are manyshowing=
impacts of other pesticides on native bees and other pollinators.Nick

Some of you, more knowledgeable than I, might want to send them some feedba=
