I think we need a cultural shift, where the burden of proof should be on pr=
oponents to show that a potentially harmful activity or product causes no h=
arm. Too often, now, those affected are expected to produce evidence to pr=
ove said harm, and that is usually unfair.
100% incontrovertible proof is almost always a theoretical construct, and =
=E2=80=9CNo evidence=E2=80=9D of a phenomenon has far too often been twiste=
d to imply that the phenomenon doesn=E2=80=99t exist.
Really, all =E2=80=9CNo evidence=E2=80=9D means is, =E2=80=9CNo convincing =
proof, so we don=E2=80=99t know for sure.=E2=80=9D
As Donnie Rumsfeld saif, =E2=80=9CThe absence of evidence is not evidence o=

Hi Nick & All,
With respect to Atrazine, and pesticides in general, I would guess that=
roughly 95% of the research effort has been directed to environmental prot=
ection. Have a look at Pesticides in the Soil Environment: Processes, Impac=
ts, and Modeling, Soil Sci. Soc Amer. Book Series No. 2., ed. H.H.Cheng, 53=
0 pp.,1990.
Spray and weigh trials are fairly straightforward but making sure that =
materials and their degredation products do not lead directly to environmen=
tal harm is a huge undertaking.

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