Yes if it did cost us Bald Eagles etc. I can do without it. Corrmorants will be shot on sight at my fish farm although I have not seen one yet. I do have Ospreys that go for my fish if I don't put up lines across the ponds.
A river near me they found about 50 rusted out barrels of DDT quite a few years back IIRR!
. The city there gets it's drinking water from that river, and it ends up in Lake Erie. Hopefully they were at least mostly empty when dumped!
As far as DDT being retained in our bodies then I must have a bunch. Would be fishing when they would come over and spray from the air!
