USA wiped out malaria in the 50s using DDT which also made the California condor go extinct in the wild. During the 70s-90s DDT became illegal to use in most countries around the globe.

I’m not sure the USA would have been successful eradicating malaria without using DDT or something similar.

DDT caused the Bald Eagle population to drop from about 400,000 birds to just 47 nesting pairs.
