The year before babies turned up with microcephaly in South America a new pesticide had been heavily trialed down there called Naled.
Real science is about Ockham's Razor. "Zika" was blamed for the microcephaly after being isolated since 1947 with no similar effects ever observed.
Guess how they propose to fight "Zika?" By spraying Naled. You couldn't make this stuff up.
