I love pineapple and buy two or three a week sometimes when they're cheap. Got a massive one for 65p today (and it's really nice as well, they usually are this time of year) and I started thinking about the actual labour of growing them, harvesting them, trimming them up, shipping them all over the world (this one from Costa Rica)... how can 65p cover that without a lot of suffering involved somewhere near the beginning of the farm-to-table pipeline? No way that a 65p pineapple is being grown and harvested by someone paid a living wage. And of course this applies to other fruits and veg too, even most tinned tomatoes are grown and processed by trafficked people in Italy in slavery conditions.
I became a vegan many years ago for moral reasons and I'm starting to see that I've only scratched the surface of ethical consumption.
