DDT works and is not harmful to the environment.
Rachel Carson was NOT a scientist or biologist. She was a sensationalist with globalist money behind her to push the one-world agenda, which requires elimination of large swathes of the earth’s population.
Carson scared the bejeebies out of a whole generation, but then it was the 60’s, and that was the period where the public opening of the Leftist agenda was introduced.
Heretofore, it was more insidious and more easily ignored by the sleepy and aspiring middle class, who could have and should have stopped it cold, given they were less than two decades from WW II.
Well, we are awake now.
