In reply to Red Rover:
Hmmmm, perhaps but surely one lesson we can already take from this situation is don't rely on some magic country 'over there' to produce everything.
I think we will all now look at international supply chains much more closely, and surely if we can all start growing veg like almost every generation before us did it's a good thing on so many levels. Good for your local ecosystem, good for your mental health to spend some hours pottering in the garden, good for your plate to be full (well semi-full, OK something...) of lovely fresh veg, good for your taste buds, good for all the food miles and packaging to be lost, good for your kids to get an understanding of where food comes from...
So get planting! Perhaps 'Dig for Victory!' needs to make a come back. I'm certainly going to be trying to get my kids to help me out in the back garden with our veg patch as part of their home schooling, wish me luck. "You can have your pocket money when you've weeded the veg patch!".
Oh, and don't get me started on the recent trend for replacing your lawn with astroturf/plastic grass because 'it's so much easier to maintain'. FFS.
