The song's title refers to deforestation (ie using the word 'stand' in its sense as a group of trees) as well as implying a desperate ultimate effort, in this case a plea to humanity to hold back the rate of consumption and environmental destruction before the damage is irreparable.
The reference to breathing is in the context of 'Conscious Breathing' as a metaphor for the Will to Live.
Today, the undeniable evidence that Climate Change is occuring as a direct result of human activity makes the song perhaps even more poignant than it was at the time it was written.
Last Stand James Hollingsworth February 1989
You can breathe Breathe the air
Feel the warm sun Shine in your hair, but...
You won't breathe Realise your potential,
In your mind, you're doing what you can, but Is it circumstantial? The bodies on the shore
They're a warning of what could happen if you don't,
No, no no, no,
Breathe the air, brave if you dare
The helplessness of necessity The guilt of new propriety
'til you can't breathe Where's the air?
Where's the lifeblood? The cure?
Oh, you know the cure? It's gone.
With... Gone with the ashes, oh! the dust is here to stay,
Ah, but couldn't we have seen? to feel? to know!
To listen before it was too late...
Too late to breathe, Too late to listen to the voices,
