Ever hear of DDT?? The EPA banned its use in 1972. It's use was responsible for the birds having soft shells on their eggs. They couldn't reproduce. The EPA and it's endangered species list, and it's ban of DDT has everything to do with the return of the bald eagle (and the peregrine falcon) to the northeast.
Yep, I’ve heard of DDT… I’ve even used the stuff… But, I thought it was the use of lead shot in my shotgun to hunt ducks that was killing the predatory birds? Oh yeah, that’s right… I forgot… When, after the ban on DDT, the birds didn’t return as fast as predicted they had to find another “thing” to blame it on.
So first let’s set the record on DDT straight. The whole DDT scare got started in 1962 when bleeding-heart tree-hugger Rachel Carson published her book
Silent Spring. In her book Carson claimed that chemicals (not just DDT) were poisoning people, wildlife and the environment. This best seller book, based on zero scientific fact, near single-handedly started what many of us call the “Environmental Wacko Movement”. In 1967 a bunch of these bleeding-heart wacko scientists and lawyers formed the “
Environmental Defense Fund” (EDF). Around the same time a guy by the name of Peakall (spelling?) had been studying egg shell thinning, finding higher DDT levels in some of the eggs. There wasn’t any scientific proof that DDT was the cause, just a suspicion… but the EDF ran with it, screaming for a DDT ban and filing law suits.
Finally, in 1971, the EDF found a sympathetic judge in the U.S. District Court who ordered the EPA to look into it. After 6-months of study the EPA
refused to ban DDT, stating they had found no danger to humans, wildlife or the environment. Well, the tree-huggers didn’t let up, and bowing to public pressure the EPA held hearings lasting into 1972. Much like the “Man-Made Global Warming” and “Lead Shot” issues, scientists from both sides gave opinions and (so-called) evidence. There still wasn’t any sort of scientific proof, just opinions and correlations… but in the end the EPA banned the use of DDT.
Now here’s the
REAL evidence… Several recent studies have shown that DDT levels have fallen dramatically during the 40-year ban, yet egg shell thickness has not increased. The egg shells from predatory birds
remain 10-12 percent thinner! So how can anyone claim the EPA saved the eagles when the ban on DDT hasn’t fixed what it was supposed to… namely, the egg shell problem?
Here in the Midwest we’ve seen the increase and return of many predators, feathered and fur bearing. Eagles, Hawks, Owls, Buzzards, Wolves, Cougar, Badger, Black Bear, etc., etc, etc… As well as non-predator species such as Turkey, Dove, Mink, Partridge, Deer, and whatnot. Eagle populations (as well as all other predator populations) have increased as their prey species has increased. We don’t shoot them on sight like we used to, and they and their prey species are managed by state and local agencies… such as the DNR. It is the actions of state and local wildlife/natural resources agencies that have brought back the eagle… the Feds (EPA) failed.
