What it means is there is less fuel essentially. Carriers are having to take measures to conserve fuel at airports where they are low and tanker in fuel when serving some destinations on the East Coast.

They've essentially abdicated responsibility for fuel economy to the automakers.

It's the Shreveport-Shanghai advantage, ... It shows that at $2 a gallon for fuel, carriers like American and United have the ability to make money.

We as a nation have no choice but to conserve fuel to the best of our abilities or be prepared for harsh measures like steep price increase, if the need so arises.

measures ... sanctions, or other kind of barriers to our markets.

To me, conservation means trying to preserve this open space, to improve on it and conserve what's here by controlling invasive species, repairing the waterways, things like that to keep landscape and habitat healthy.
