Thanks, Melanie, or a once-again very carefully researched piece. Lots of interesting details - I got hung up on the fact that wheat had to be bred to hold onto the seeds so it could be harvested. That little piece had never occurred to me before.

I'm worried about what a shortage of wheat from the Ukraine crisis will mean for worldwide food...

Thanks, that little detail about the way wheat holds the seeds seems so tiny but is so important. The detail that caught my attention was the bit about higher carbon dioxide levels affecting water uptake. The world is such a complex place. I admit I'm worried too, the impacts are so huge from this war.
