Is it only ethical to eat meat you kill yourself? We interview author and journalist Louise Gray, who spent a year doing just that.We find out what it's really like inside an abattoir, how likely you are to be a psychopath if you work there, and whether the thrill of the hunt is a real thing.  And we ask: should everyone be prepared to kill animals if they want to eat meat?Louise's book, 'The Ethical Carnivore', is out now.Sustainababble is your weekly comedy podcast about politics, prattle and the planet.Music by Dicky Moore from Bearcraft and Dream Themes.Available on iTunes, Stitcher, Soundcloud, and on sustainababble.fish.
