The best scientists have open minds, open ears, and humility.

My favorite bugbear is the intellectually dishonest  use of =E2=80=9Cno =
evidence=E2=80=9D to disprove or discredit a hypothesis.  All =
=E2=80=9Cno evidence=E2=80=9D means is =E2=80=9Cno proof.=E2=80=9D =20

=20

Either way.

Hi Lance

The time frame what I referred to was the 1950/60s.

I talked to them then and was told I didn't know what I was

talking about! It was over hunting.

Glad to see they came around to the truth - only took 50 years!

Like when coyotes came to Nova Scotia. Oh no, they wouldn't

kill deer.=20

Have a nice winter

Paul

Hi Paul,

You may find a small amount of comfort knowing that that isn=E2=80=99t =
always the case. In a 2012 environmental assessment report of the impact =
of the realignment of the Trans-Canada Highway in PEI the following can =
be found:

=20

=E2=80=9CRoad salts that contain inorganic chloride salts are considered =
=E2=80=9Ctoxic=E2=80=9D as defined in Section 64 of the CEPA=E2=80=A6 =
Environment Canada determined that the development and refinement of =
Salt Management Plans is the best mitigation against potential =
environmental effects from road salt use.=E2=80=9D

=20

Also, Environment Canada has issued a number of bulletins regarding road =
salt as well. This from an August 2000 bulletin:

=20

=E2=80=9CBehavioural and toxicological impacts have been associated with =
exposure of mammalian and avian wildlife to road salts. Road salt =
increases the vulnerability of birds to car strike and may poison some =
birds directly. To relieve thirst, birds may ingest snow which could =
have negative energetic consequences; consumption of meltwater =
containing high concentrations of salt may increase salt ingestion =
rather than alleviating salt toxicosis. Road salt may also affect =
wildlife through its impact on habitat, with reduction in plant cover or =
community shifts that could affect wildlife dependent on these plants =
for food or shelter.=E2=80=9D

=20

Of course whether decision makers heed these warnings is another =
question entirely.

=20

All the best,
