Lead in the water
Before we get a gale force debate going on lead in the water, I have a couple of thoughts.How much lead naturally occurs in the Great Lakes? Is lead not harmful, in and of itself, and only harmful when ingested?If memory serves me right, I think a .50 caliber slug, prior to impact is right around 1/2" x 2" in size. That's quite a mouthfull.Won't these exercises be taking place well offshore, in deep water, where bottom-feeding is not common?How much lead is there in the dust going overboard when loading taconite and other ore in Duluth and other ports?Are we using a standard that implies that anything man puts into the lake is harmful?Isn't 7000 lbs about the weight of a couple of sub-compact cars? Did we ever lift that Yugo off the floor of the Straits of Mackinac?Is it possible that naval gunnery involves other elements not found in shore side gunnery and artillery?Would we be doing more, or less, pollution to Gaea if we flew/drove these trainees to the ocean to do the same thing? Is the ocean's only difference that it is not in my back-yard or does it actually ingest lead more readily?Lastly. Aren't "serious Canadian concerns" being amply addressed by junior high school debate clubs all across the nation already?
