I believe we already import a lot of wheat. There was a program about it last year, we as a nation are suffering from a lack of selenium in our diets because quite a lot of wheat is coming from Cnada which doesn't have selenium in it.
And drinking anti-dandruff shampoo for the Selenium isn't much of an option. It's interesting that you can tell by someone's molars where they lived most of their life because of trace amounts of various isotopes being different in the soil.
I wonder however how much of the dearth of wheat in the UK is due to tariffs and subsidies having caused farmers to grow different crops, and how much of it is actually due to climate shift.
(For the record, I'm not one of those people arguing against climate change in face of overwhelming evidence - particularly with record drought in the NL at the moment and my airco running pretty much the entire day just to keep sane.)
This amount of awesome cannot be from concentrate.
