Is it necessary to airlift blueberries from Peru to Canada in January, and green beans from Kenya to London? The vitamin C and roughage these foodstuffs provide can be secured from many other sources with much lower carbon footprints.

Why not do what can be done, profitably and immediately, rather than waiting for more modeling exercises?
