I've always been vegetarian but I'm not sanctimonious about it. The way I see it, as my family was vegetarian it wasn't a conscious choice I made. Who knows what I'd be doing if I had been born into a family eating meat and two veg every day. I also have huge space to improve my environmental footprint...the clothes I wear have probably been stitched by kids working long hours, I don't always remember to take a bag with me to the shops, quite a lot of my diet is imported...etc..
My point is, unless we're living off the land and making our own clothes we're all affecting the environment and we can all improve where we can reduce our impact on it.
All that to say....I was watching a show with some friends about how race horses, once past their point of use, are often shot. This was accompanied by protests of "that's so sad, so cruel" etc.
I wondered how it's any different to raising a pig for food and killing it once it's fat enough. Or a chicken for eggs and killing it once it doesn't lay eggs. To me, the horse may even have had a better life than animals raised for meat, since there is an onus on the owner to make sure it's well fed and kept healthy.
Of course, ideally I'd like the horse to live out it's natural life in retirement. I'd like all animals to live out their natural lives. But I can see why that might not be feasible for the owner.
I really don't understand why some animals are okay to eat, but others aren't. Why is okay to eat pig but not dog? Why chicken but not parrot? Why cow but not horse?
Please could you educate me?
