Interesting look into the mind of researchers with an agenda.

As onthewater102 pointed out, they have combined "suspected" with actual lead tackle deaths, and throw that figure around as the total for actual lead deaths. If the study were a study and not an attempt to sell an agenda, the "suspected" numbers would be added to the unknown, not those that are provably fishing tackle lead related.

Even the layout of the chart is misleading. Charts quoting percentage should show the scale on a 100% basis. but it doesn't look as dramatic when you only fill a small portion of the scale, so they left off the empty side.

To be honest the thing that stood out to me as the oddest, is why do loons in a fresh water environment attack each other (intraspecfic trauma) but none in a saltwater environment do.
