In relation to Noel Fitzpatrick I think the use of bionic limbs in animals is a very good ethical/controversial thing to talk about. Naturally we as humans anthropomorphise animals and their ‘desires’ so many would believe sticking a biopic limb on animals like horses would benefit them when in reality could cause a lot of stress. The same for very activate working dogs, you would probably cause more stress but it’s a deep and emotive topic! It’s also a bit more niche than the standard ones of animal testing, badger culling etc.
Something also quite topical is the breeding of particularly dogs for fashion with Norway banning breeding cavaliers and English bulldogs due to the welfare concerns.
