If social control/authoritarianism is something to be avoided - what do you propose be done about population growth?  (expanding the discussion focus to total global population)
I think that government interference in reproductive rights infringes on liberty but as is becoming apparent - we are entering into an age of consequences for our refusal to confront and solve problems and in many cases we are left with no palatable choices as to solutions, what do we do?

1. Declare it a non-problem and ridicule those who say it is? (the FoxNews approach)
   
2. Repeat that any attempt by 'authority' to control reproduction is evil? (ignore the question)
   
3. Refer to some sort of market based self correcting 'thing' that will solve the problem but leave out any explanation of how that is going to work (or distract/derail attempts to discuss solutions)?
   
4. Ignore the problem and be confident that the coming civilization train wreck will 'probably' happen after you die so what do you care if the shit hits the fan then (then repeat #2)?
   
5. Subscribe to the idea that IF the problem is real THEN a massive die-off and global civilization meltdown is inevitable (aka the Rapture/Eschaton/party over) - so keep making money, doing nothing to avoid disaster, fight any proposals to do anything about it, and hope you don't live to see it?
   
6. Other?

Perhaps we could have a law whereby the more kids you have, the closer to Ethiopia you have to live.

It's the end of the world as we know it, and I feel fine

Generally speaking, it is good to allow individuals to make their own choices about their own lives; we all value our personal freedom.  So the idea that people should be free to have as many children as they want to seems very reasonable.  Still, that freedom is what has given us a world of over six billion people.  I personally can remember when there were only three billion, so the change is very dramatic within my own lifetime.  And what if this continues?  What would life be like in a world of twelve billion people?  I won't live to see it, but your children may.  And I predict that if they do, they won't like it.  There will be terrible shortages of food and water (there already are in many countries, but they will get worse everywhere), the world will grow ever more polluted, housing will become more scarce, all resources will become more scarce, people will increasingly fight over access to scarce resources of all sorts.  Problems of global warming will be impossible to solve, because even at a reduced level of consumption of resources, twelve billion people will consume too much and produce too much waste.  So we need to think about the larger picture of what the human race needs, and not just about what you personally want.  And this need, realistically, is more important than individual freedom of choice.  Sad to say.

I suspect they're worried about the reproductive rates of those evil immigrants.  Because Britons have an average family size of 1.79 children per woman which is under minimum rate for maintaining a population level.
