Population Control: My Prediction

I have a, slightly odd, prediction for how the population will be controlled in the future.

It came to me while watching the BBC TV programme, Protecting Our Children.

I think that at some point in the future there will be a compulsory contraception programme effectively sterilising the human race and that people will have to apply for permission to have families. Much like the adoption process now.

Not quite Nostradamus; just a thought.
