Well, start with the conservation status of the birds. Both species are rated as "Least Concern" -- which means no identifiable conservation issues.
In the 1950s there were only 412 nesting pairs of bald eagles in the US, due to hunting and DDT. By 1995 they were taken off the endangered lists, and five years ago they were taken off the "threatened" list. By now there are nearly ten thousand breeding pairs in the lower 48. Half of US states have at least 100 breeding pairs.
From an environmental viewpoint it's quite reasonable to stop treating an occasional accidental bald eagle death as some kind of serious event. For healthy population, an individual removed is room for another individual, just as with reasonable levels of deer hunting. Emitting more carbon in order to stop a handful of eagle accidents makes no sense at all.
