The link above describes the province Torba, part of the South Pacific island Vanautu, in its decision to halt importing foreign food. The leaders of the province note that the area is self-sustaining, and those who have indulged in western junk food have started to notice health problems.
I think it is fascinating that in the era of globalization there are still opportunities to create local communities with little outside influence. This article also points out a large disparity between the food industry in America and other areas- in the US, eating organic and local is considered a luxury for many; meanwhile, in Vanautu, it is the normal way of life.
Hopefully this decision inspires other regions to follow suit and switch their food systems to more localized alternatives.
