Once you’ve decided that other creatures are sentient and that it cruel to sacrifice them for the sake of protein there’s only one place you’ll end up and that’s hungry.
And I don’t just mean that you have to eat an awful lot of Linda McCartney burgers to fill your stomach. Sooner or later someone will prove that plants have feelings too and it isn’t just meat that is murder.
It seems that day is a little closer with scientists at Bristol University proving that plants communicate by passing sound through the ground, while in Exeter others have demonstrated the way plants respond to wounded comrades.
If I were a vegetarian, I’d be worried because the day can’t be too far away when everything is off the menu.
There’s always water of course, although that might also prove to be an ethical dilemma, as illustrated in the Hitchhiker’s Guide to the Galaxy:
Ford Prefect: ‘You’d better be prepared for the jump into hyperspace. It’s unpleasantly like being drunk.’
Arthur Dent: ‘What’s so unpleasant about being drunk?’
Ford Prefect: ‘Just ask a glass of water.’
And as Arthur concludes, you’ll never be cruel to a gin and tonic again.
