I was issued with a challenge the other day:
ok you show me that as veganism has increased, animal slaughter has decreased.
Which in my mind is nonsensical, because
There are other factors at that could push numbers up (e.g. cheaper/more convenient meat)
It's the basic rules of supply and demand
It applies equally / more so to vegetarianism
but I feel I should answer it; he has asked me to give him some sources after all and he is a good friend of mine, so I can only assume it comes with some sincerity...
I was wondering if anyone had some good sources to go with here. I found some good ones myself, like this, this and this and I think the US one is in fact pretty damning (when you look at the drop between 2014 and 2017) but the UK statistics (my country) are not as helpful, partly because they stop at 2014.
I wonder if there is a stronger way I can show this correlation or perhaps I should approach it as proving the dynamics of supply and demand? I would love to say "why does Nokia not manufacture the 3310 any more?" but of course they recently started doing that again haha. Has anyone got a really good example of something that was really popular that has now effectively died out due to lack of demand?
