When was the last time anybody actually managed to starve to death in Great Britain? Great Britain is already a welfare state. It's easy to get paid for not working. If you fall through the cracks of that system there are dozens of charities devoted to helping those in genuine need. In addition, there's a beggar on every street corner. Oh, and there's always the Church, which really should be working on feeding the hungry itself (perhaps by reducing its own gold-plated candelabra budget) instead of sending 'em to knock over Tesco's.

Finally, if you somehow manage to be completely unable to find food anywhere, and you haven't eaten for days and you're actually in danger of dying of starvation, all you need to do is go to hospital, where they'll say "hey, this guy is dying of starvation" and give you free food and medical treatment.

In conclusion, dying for lack of food in modern Britain is very, very difficult.
