I'll start, if I may. In order to answer that, I need to just lay a little bit of groundwork about what we mean by the ethical use of animals in sport and otherwise, and how we assess welfare. So, I'll do that briefly, if you don't mind bearing with me, please.
There's a lot of discussion at the moment, in the public, obviously, about the use of animals in sport—generally horses as well as greyhounds and sled dogs. There is an argument that has developed that goes along the lines that there is something ethically distinct about humans using animals for competitive sport compared to for all other purposes. And the reason it's ethically distinct is because it's uniquely trivial, and the reason it's uniquely trivial is that the benefits to humans are trivial. So, they are benefits around social factors, enjoyment, and it has also become confounded with societal arguments around betting, which I won't begin to go into now.
I don't accept that starting point that there is something uniquely trivial about using animals in sport compared to using them for all other purposes. I'm using the word 'use' advisedly, because that's what we do when we keep animals for food production, when we use them in medical science, and indeed if we keep them as companions. All of those human uses of animals expose animals to at least potential harms, and in fact, if you think about it, the benefits to humans from all of those, with the exception of using animals in medical science, are also trivial. So, we don't need to eat meat or drink milk. We don't need to have dogs as companions. Many pet dogs get left for hours each day, and so on and so forth. So, that argument around unique triviality, I don't think stacks up from an intellectual point of view.
Now, if you take an animal rights point of view, in which you don't believe that humans ought to use animals at all, and you think that animals have an absolute right to free will, and not to having what they're doing dictated by humans, then it would be consistent to reply to what I've just said, 'Well, that's fine, okay, it's not ethically distinct using animals in sport because it's uniquely trivial; they may all be trivial uses of animals, but none of them are acceptable from an animal rights point of view because they take away the animal's free will and expose them to at least potential harms.' That would be a perfectly valid philosophical point of view if you applied it across all human uses of animals. And, of course, some academics do, and people such as Professor Andrew Knight, who is a proponent of a vegan diet, for example, and very consistent on that, but that's not the majority societal point of view. Generally speaking, we do allow the use of animals, provided that their welfare needs are protected.
And that's where we come to the welfare part of this, which is really important. I do work—
