Dried-up Arctic ponds evidence of global warming, study says

A University of Alberta scientist has uncovered dramatic evidence of climate change in the Arctic, where ponds that have been part of the landscape for more than 6,000 years are drying up as global warming has nearly doubled the length of the brief northern summer.

Imagine for a moment that we bought food in the way we currently buy electricity. We might order from a supply list with no prices marked and have whatever we fancied delivered to our door whenever we pleased. A single, un-itemized bill would arrive in the mail once every couple of months covering all the food ordered and delivered during the billing period. How would our food bills probably compare to what they are currently? How would we go about reducing our food bill in order to save money when we know nothing about the cost of each act of consumption? If the 'Ministry of Food Supply' were worried about the amount of food available, reliance on expensive imports or whether the delivery system might not be up to the task, what could they do to encourage a 'food conservation culture'?

What is missing from our hypothetical scenario is real-time price feedback, which would allow consumers to take responsibility for their own consumption. Its absence makes the task of trying to reduce demand much more difficult, both for consumers and for those trying to manage the supply. If we are ever to introduce a conservation culture, the tradition of passive consumption must first be challenged.
