You are absolutely correct. The banning of DDT was all based on junk science.
Ruining birds eggs and its bad effect on humans were disproved.

"The environmental movement used DDT as a means to increase their power. Charles Wurster, chief scientist for the Environmental Defense Fund, commented, "If the environmentalists win on DDT, they will achieve a level of authority they have never had before.. In a sense, much more is at stake than DDT."

To entice you to read what I posted on reply #60, here is the section on the bald eagle:
VII. Bald eagles
DDT was blamed for the decline in the bald eagle population.
Bald eagles were reportedly threatened with extinction in 1921 -- 25 years before widespread use of DDT.
[Van Name, WG. 1921. Ecology 2:76]
Alaska paid over $100,000 in bounties for 115,000 bald eagles between 1917 and 1942.
[Anon. Science News Letter, July 3, 1943]
The bald eagle had vanished from New England by 1937.
[Bent, AC. 1937. Raptorial Birds of America. US National Museum Bull 167:321-349]
After 15 years of heavy and widespread usage of DDT, Audubon Society ornithologists counted 25 percent more eagles per observer in 1960 than during the pre-DDT 1941 bird census.

Statistical analyses of Audubon Christmas Bird censuses. Letter to New York Times, August 15, 1972]
No significant correlation between DDE residues and shell thickness was reported in a large series of bald eagle eggs.
[Postupalsky, S. 1971. (DDE residues and shell thickness). Canadian Wildlife Service manuscript, April 8, 1971]
Thickness of eggshells from Florida, Maine and Wisconsin was found to not be correlated with DDT residues.
