Organic farming would be nice if it was at all sustainable for humankind. I haven't developed this thought much but to me it might be hypocritical to eat organic because it creates the maxim which states that the 90%? Of the worlds population who do not have access to this type of agricultural produce should aim to get it, but if they did the world food production would fail.
Anyways, growing your own food and exchanging subsistence with others is probably the only way to ensure organic... people cheat.
