What do you think Sarah McLachlan's song 'World on Fire' means?

Question

Here are the lyrics:
The worlds on fire its more then I can handle
Ill tap into the water try and bring my share
Try to bring more, more then I can handle
Bring it to the table
Bring what I am able

Hearts are worn in these dark ages
Youre not alone in these stories pages
The light has fallen amongst the living and the dying
And Ill try to hold it in
Yeah Ill try to hold it in

Chorus

I watch the heavens but I find no calling
Something I can do to change whats coming
Stay close to me while the skys falling
I dont wanna be left alone dont wanna be alone

Chorus

Hearts break hearts mend love still hurts
Visions clash planes crash still theres talk of
saving souls still colds closing in on us

We part the veil on our killer sun
Stray from the straight line on this short run
The more we take the less we become
The fortune of one man means less for some

Chorus

If I'm not mistaken, this song is in reference to the state of the world today.
