Invasion imminent

It seems they’ve set their evil plan in motion
And secretly released those greenhouse gases.
The gaping hole above the Southern Ocean
Will spell the end of our collective asses.

The only thing in space they feared was ozone.
The strongest of their missiles couldn’t dent it.
A world with such a layer was a no-go zone
Until they found a way to circumvent it.

And, as the hole grows larger, they’ll come streaming
Through the layer that once protected us.
And we’ll fall victim to their dev’lish scheming
And suffer as a conquered planet does.

It will be a lamentable occasion
When conquered by these warlike Cosmic elves,
But the worst thing in regard to this invasion –
We’ll think we’ve orchestrated it ourselves.
