Thanks for this link, re Bird Flu: a virus of our own hatching by Michael Greger.
Had a look at some of the chapters; seems over-excited – working towards the flu’s gonna kill us all (or lots of us) scenario: so John Oxford liking it not real amazing, as among the folk who evidently build careers and reputations from scary flu stories.
Mentions re flu evolving in chickens – fair enough.
But then, seems no real consideration of flu also needing to evolve in humans: we aren’t going to die from a pandemic chicken flu.
Any chickens who are reading should be scared – tho factory farmed chickens might think the flu could help put them out of their misery.
Readers who are humans should take with very large pinch of salt.
