When we stop to think about it, we generally agree that we want our food supply to be sustainable and ethical. When we lived in the UK I subscribed to a brilliant organic fruit and veg box from a local farm that was delivered weekly. I had milk delivered by my local milkman and I tried to shop either at the farmers' market or by choosing British foods at the supermarket. Since moving to Hong Kong, though, I have had a few problems with buying local food.

I wrote before about buying milk in Hong Kong - there were no good options for me. In the months since that post my husband and I have still been trying to find good quality milk. A lot of the time we resort to milk that is flown here from great distances: Australia or the US. This troubles me.
