The world has sprung a leak.
We'd better get off.
It may be too late.
The hull's starting to cough.

I think it the best
Course to look for another
Place to infest,
Somewhere else in space.

Errant earths
Are very cheap;
Many births,
I am told, keep

Moving things along,
Keep proliferating
New stars, new suns
New inhabitable planets.

But I doubt,
Once we get going
And we're not kept out,
If they can give birth

Fast enough
To prevent the worst:
Keep us off
Before we pollute
The entire universe.
