If I could go back in time,
I'd stop the Plague from spreading.
But what if that caused overpopulation?
I don't like where that's heading.

If I could go back in time,
I'd prevent the first World War.
But that just makes the Second World War the First.
I must think of something more.

If I could go back in time,
I'd warn against pollution.
But maybe man needs to find out for himself,
Not be granted absolution.

Perhaps it's not the best idea,
To try and change history.
Maybe we should look to the future instead,
And make it the best it can be.
