I remember this conversation because Rush was discussing how people were trying to shut down his residence in Florida due to “BS of lights on the beach and turtle”.
I have lived in Africa and Rachel Carson was doing the work of her Father, the devil, when she wrote that book and used it to shut down DDT.
Rush discussed the DDT ban several times in the run of his show but this was one example I quickly found and he would rebroadcast such calls/monologues when he was on the air because they quickly covered the basics of the issue (that never seems to go away).
If he was still on the air I’d expect him to reference it from his stack of stuff at least once in the current 2 week span of this study getting press.
