We have met the enemy and he is us!
1. Lead kills us and there is no safe level for lead. Before the 1990's the thinking on this was very different. Now the CDC and other health organizations tell us not to handle lead. We ingest it if we smoke or eat snacks after handling it.
2. The British experience. Swans on the Thames River made a dramatic come-back after lead in fishing tackle was banned. The swan numbers were spiraling downwards prior to the ban.
3. Birds such as loons will ingest items looking like food. Therefore, flies with lead are more likely to be consumed by loons than lead shot from shotgun shells.
4. If WE are not part of the solution, then WE are part of the problem.
" Fishermen, hunters, wood choppers, and others,
spending their lives in the fields and woods,
in a peculiar sense a part of Nature themselves,
are often in a more favorable mood for observing her,
in the intervals of their pursuits,
than philosophers or poets even,
who approach her with expectation."
Henry David Thoreau
