Carbon-neutral foods

The biggest problem with modern food production is that it is entirely dependent on oil. We've already seen food costs rise as a direct response to rising oil prices.

Many farmers have profitably moved their food production over to organic methods, I wonder how long it will be before we see certified carbon-neutral foods on our supermarket shelves?

I'd certainly be happy to pay a premium initially in the sure and certain knowledge that as oil runs low my food prices will remain stable.

I can see that there would be degrees of carbon-neutrality. The foods that still use oil, but are carbon-offset, the foods that use no oil in production and the farms that use no oil in production or distribution.

All plants should be fertilised using non-oil derived fertilisers. The by-products of plants such as the unused stems and leaves should be put into bio-reactors to produce fuel or fertiliser. All farm animals should be fed on carbon neutral food stuffs and their by-products should be recycled for fuel or fertiliser.

A collective of farms could work together: One specialising in producing plants for food and fertiliser, another producing fuels and yet another producing meat, fuels and fertiliser. Each farm would work to offset the others' needs.

I don't know when this will happen, I only know that it will have to happen.
