I am still not convinced that local anything is more eco/carbon friendly. Think the Law of Comparative Advantages - in certain areas my lunch will be way more eco/carbon friendly if I only spend the whole day producing guns instead of butter. Also I suspect that huge farms employing high end software, hardware and even weather prediction technology are more eco/carbon friendly than any local farmer can ever be.
