End of the world

Here is the situation.

You and your daughter are the only humans left on the planet.
What do you do?

If there were 2 people left on modern earth, it would be only a matter of time before they would die. Man's impact is quite a bit. Even if you were to reproduce, you would be inbreeding inadequacies of already similar genes. The chance of a benificial mutation that would allow population to regrow, overcoming these inadequacies will not happen at the rate at which you can reproduce. Thus, down to a father and daughter, reproduction would be foolish. That is if this was a matter of the preserverence of our race. As for a sexual connotation, they still have their hands...best to leave it at that.
