While a quivering finger of accusation has been pointed at agriculture over its role in generating greenhouse gas emissions, it seems to have slipped peoples' attention that farming serves our cities.
Agriculture keeps cities alive, in the most fundamental sense.
And those cities are not without stain when it comes to pumping out greenhouse gases.
City dwellers will presumably help carry any carbon penalties incurred by agriculture, should ag be eventually included under the emissions trading scheme. But that's some time off, if it happens at all.
In the meantime, where's the talk of smartening up our sprawling, inefficient, polluting urban areas?
Right here, as it happens. Author Juris Greste comments: "Expecting to meet the carbon challenge without adjusting our cities is like telling your doctor you want a lung cancer cure without giving up smoking".
If we're going to be in the business of driving carbon out of the economy, it would be nice to know that we're all in it together.
