I've arranged to speak to Peter Singer for the podcast I co-host, at some point in early October. The focus will mainly be his upcoming book Why Vegan? but there will be scope to discuss a range of topics besides.
If you have a question you would like to ask him, we would love to hear them. If there are > 5ish suggestions, Luca and I will pick our favourites (weighted by upvotes). Bonus points for originality – would be great to be able to ask some properly novel questions!
