A vastness, receding

I wrote the following poem for the Climate of Our Future blog. My post there (Lake Superior disappearing) includes both the explanation and inspiration behind it, in case it's too abstract.

A vastness, receding
by Francis Scudellari

A vastness, receding
Too far, ceding
Its depth, ceding
Its breath, ceasing

Fresh source, all life losing
Too soon, loosing
Vapor, loos’ning
Its grip, less’ned

Superior, slipping
Too low, sloping
Shallows, lifted
To be swallowed

Up-down cycles, breaking
To spirals, brought
Burdens, brokered
Its costs, broadened

A greatness, receded
To nothing, lost
Its essence, slipped
To bed, broken
