Spanish flu?
a global wamingist, save-the planet dude’s wet dream, indeed.
Yep. The 1918 Spanish Flu Pandemic killed off 50 million evil, CO2 exhaling, planet-warming humans.
Why was it called "Spanish Flu"?
Because it first received widespread media attention in Spain.
The flu epidemic had started during World War I in 1918. The warring countries had press censorship and censored reports of outbreaks of the flu. Neutral Spain has no wartime press censorship so the rest of the World learned about the flu from Spanish press reports of a flu epidemic in Spain.
