That Neil Ferguson clown from Chinese Imperial College London said Britain had to slaughter ALL of its livestock to prevent the spread of BSE in 2001. ALL of it, not just cows that might be infected, but cows, pigs and sheep just in case it might jump across species and across the country. Britain literally slaughtered and burned 30 BILLION dollars worth of livestock across the whole because of 250 cases of BSE in a single region.
Dozens of experts analyzed what he knew and when he knew it and all came to the same conclusion: the guy was 100% wrong.
Somehow he still has a job and people still listen to him.
That same guy is the one who said we had to shut the whole world down to contain this thing.
