As far as the lead issue again, do we really need a study to tell us exactly what is going on here? is there a number of loons that die per year from lead ingestion that is acceptable to everyone? like if only 100 die per year then oh that's ok, so long at it's not 200? if there's a chance that something i leave in the environment could be responsible for wildlife dying, that's good enough reason for me personally to make a commitment not to leave it. lead is proven to be deadly if ingested. doesn't it make enough sense that we shouldn't be leaving chunks of it in lakes and rivers?
See, this is the point - what is the level of the impact? Again, I feel kind of weird taking up the devil's advocate position here, but degree is something that should be addressed.
We kill fish and various wildlife all the time when we go recreate, be it by discharge of gas and oil from our motors, or fishing line fouling up birds, or any number of things. So if the criteria is it kills some loons and so should be banned, then we better get ready to just sit in our rocking chairs and do nothing.
I think the word LEAD has such an ugly connotation to it that we mistake the banning of it as doing something meaningful when in fact there may be other more effective ways to protect wildlife. For example, how many birds die from fishing line every year? I'm going to take a guess that it is far more than from lead. So let's ban all fishing line that isn't biodegradable and out of the environment in say a 6 month window. Now we are talking about a REAL impact on wildlife mortality. If you're in favor of a lead ban, I'm sure we can start coming up with a nice list of things to ban that are much more harmful every year. Not picking on you Nik, just wondering sometimes how we as a society prioritize different actions to take.
Here's an interesting bird mortality study on various human interactions with birds:
Bird Mortality
And the author's conclusion statement:
"Based on existing projections and projections made in
this paper, annual avian mortality from anthropogenic
causes may be near 1 billion".
