Assuming the harm of both actions to be equal, this is only really a fair comparison if eating meat and punching your neighbour is equally costly.
I’d argue that not-eating-meat is costly, and not-punching-your-neighbour is cheap (or personally beneficial) in the medium to long run. (That deciding not to eat meat is currently costly sucks and should be changed.)
Quick thing anyone could do, to make this book (or any other book you find valuable) more available.
Most university/city libraries offer the possibility to recommend books to them. I`ve done this myself many times (also for this book) and my university library sofar ordered every book I`ve recommended.
