'We'll all'?... Where the hell do you think these 'kitchen gardens' will be given that most families can barely afford to buy a flat, that renting won't allow them that option, and that new builds have gardens like pocket handkerchiefs?
That's without considering the time that is needed, or the skill (I've tried growing veg and not done hugely well). The only option then is to pay someone to do it for you.
So, an option for the affluent retired, but families will no longer be able to give their kids fresh produce.
Alright! Point taken, I didn't think it out that far, should have said "Some of us will have kitchen gardens in the future". I did say I'd never tried it but I know lots of people who've grown runner beans, tomatoes, onions, carrots and other stuff - e.g. potatoes and asparagus - in a small garden. As well as fruit. Yes, I agree impossible for people in flats with no outside space and you're probably right that it takes a lot of skill and dedication, I wouldn't know. Maybe I'll find out in the future.
It's also possible to buy fruit and veg grown here which will mean only when in season, I do when I can. Great big gooseberries and rhubarb spring to mind, better than from supermarkets. On the edge of London there are plenty of farms and small shops stock their produce as well as farmer's markets.
It may not come to that though, let's hope. I haven't yet given up hope of Brexit not happening.
I fail to see what any of this (Brexit) has to do with religion or lack of. Agree with Trent.
