Canary

Our space is limited
It's getting crowded
The river has dried up
The air is looking clouded
Please come back, friends
We really messed up
Please come back, friends

We say "Don't you judge how we live
The Earth will always give and give
There is no end to our riches
We'll keep building streets and ditches"
Now those pigeons are all gone
Nevermore to block the sun
With their flapping wings of glory
Oh that death so strange and gory
