The "food miles" theory says that the further food has to travel to reach its destination - such as food imported to Europe from New Zealand - the worse it is for the environment because of the greater quantity of pollutants emitted during transport. Researchers in New Zealand, where farmers and ranchers had a good deal of revenue at stake due to their remote location, put the theory to the test and came up with some interesting results.
Their overall conclusion was that the number of miles a food had traveled was not a reliable indicator of its environmental impact. Many forms of produce, as well as dairy and sheep meat, were found to be more energy efficient even when travel to Europe was taken into account. A similar study in the UK produced the same results.
This does not mean that buying goods from far away is necessarily "better" than buying local goods. It simply means that the method of production is what counts, not overall distance traveled, if environmental factors are a primary consideration when purchasing food. Locally produced food may be better in some cases, but it might not be if it is not responsibly produced in the first place. Buying local is a great way of supporting the local economy and keeping revenue within the community and for consumers who make that a priority, local still might be a better choice.
