Morals of buying apples

[mr_hanky]

A quick question:

In your opinion what is the most valid ethical reason to buy locally produced apples over imported nicer tasting apples flown in from Africa?
a)supporting local economy?
b)environmental?

My thoughts are that buying locally produced apples supports the local economy, providing jobs to local people etc. But buying apples from Africa supports a foreign community that would probably benefit more from the money.

Buying locally produced apples has a smaller impact on the environment compared to flying them in from Africa (the carbon emmisions per apple are probably at least 10x less).

thanks
