Jez Lowe's song, Galloways, about the pit ponies after the pits were abandoned.
Si Kahn's song, Aragon Mill, about the town of Aragon, Georgia, after the mill shut down.
Jean Ritchie's song, The L & N Don't Stop Here Any More:

For I was born and raised at the mouth of the Hazard Holler
Coal cars roaring and a tumbling past my door
Now they're standing rusty, rolling empty
And the L & N don't stop here any more

Sam Richards' song, Goodbye to Saint Lawrence, chronicles the end of two industries, fishing and mining. Here's one stanza:

When my old feller had breathed his last breath
Like the others who suffered 'longside him
The Company flooded the mines and pulled out
Too few dollars in St. Lawrence mining
Too few dollars in St. Lawrence mining

Matt Armour's song, Generations of Change, absolutely first-rate song.

Archie Fisher's song, Final Trawl:

Now it's three long years since we made her pay
Sing haul away, my laddie-o
And the owners say that she's had her day
And sing haul away, my laddie-o

Stan Rogers, Make and Break Harbour:

In Make and Break Harbour the boats are so few
Too many are holed up and rotten.
Most houses stand empty old nets hung to dry
Are blown away lost and forgotten

Another Stan Rogers song, Free in the Harbour:

Free in the Harbor; The Blackfish are sporting again
Free in the Harbor; Untroubled by comings and goings of men
Who once did pursue them as oil from the sea,
Hauling away! Hauling away!
Now they\re Calgary roughnecks from Hermitage Bay,
Where the whales make free in the harbor.
