There’s an excellent piece here on Sp!ked by Rob Lyons demolishing the case for “local” food – and, by implication, beer:
Let me state my position baldly: there is no problem to which local food - or at least buying your food within some predetermined distance of home - is a good solution. Despite the claims of some campaigners, local food won’t save the planet, it won’t make us healthier, it won’t restore traditional communities and it doesn’t offer greater food security.
The big claim usually made in terms of the environment and local food is that we should be trying to reduce our ‘food miles’. It seems to make sense that the shorter the distance between fork and fork - between the one in the soil and the one on our plate - the better. The trouble with that theory is that transport from field to warehouse to shop is just one small part of the total environmental impact of our food.
Insisting on local food could actually increase the environmental impact of what we eat.
