Why does organic food cost so much?

Good question, Greg. This could be a very very long answer, but here's a short version.

1. Organic food is simply more food, as it has consistently been shown in scientific analysis to contain more vitamins, minerals, phytonutrients and general goodness.
2. On average, organic food grows more slowly than non-organic food, because the reason non-organic farmers spray chemical fertilisers on their crops is to speed up the process. Time is money when your making anything. Longer growing time is also one of the reasons that organic food tastes better, as the produce is allowed to ripen more naturally and to get the tasty nutrition it needs from the soil.
3. Buying cheap non-organic food hides the fact that you're paying for it once at the checkout, once again through your tax subsidies, and yet again through the tax money the government spends on cleaning up all the mess caused by chemical pollutants from non-organic farming.

The very very short answer is quite simply, you get what you pay for.

But if you want highly nutritious, highly delicious food that is humanely made and doesn't cost an arm and a leg, I strongly suggest you find your local organic box scheme or farmers' market, as they're often far cheaper than supermarkets for higher quality organic produce.
