“Every vegan seems to have their own lightbulb moment when something clicked and they stopped eating animal products,” says Cambridge University archaeologist Dr Pía Spry-Marqués – who committed to a plant-only diet two years ago as she researched the history of pork.
‘I started thinking about how it’s weird to drink cow’s milk.
I was writing the book and researching factory farming and pigs nursing piglets and it was all too much.
I decided that I would go vegan the next day.
And that was it’.
As Dr Spry-Marqués immersed herself in the history of pork – from the Paleolithic era to now- she learned about how pigs are relatively sensitive social creatures which can express empathy.
And about the extremities of industrial farming where pigs are castrated without pain relief and kept in harsh cramped conditions.
And how the byproducts of this process end up in all sorts of items from paint brushes to medical gauze to yoghurts and bone china.
