I've come from far to save your world,
The green multi-eyed alien said,
We've watched you well for centuries,
When this one ends you'll all be dead

Your atmosphere is poison full,
Your oceans are polluted too,
All your stars will vanish from sight,
Your skies no longer will be blue

You have to take more drastic steps,
To change your very careless ways,
And don't take years to do all that,
Think more in terms of months and days

This warning is for just one time,
Because I won't be back again,
If you don't do just what I say,
All your regrets will be in vain.
