Trouble with a survey like that is the people expressing their opinion do not have the full facts.With a birth rate in this country of 1.7 per family,we are a long way off the 2.1 per family required to even replenish the current population.Population increases are also due to an aging population,living far longer than ever expected when plans were made for their retirement,who need a young population who will be working and paying taxes that will support them.We also have a large immigrant population and a subsequent immigrant baby boom,so you need to take that into account too.On a world wide scale that would be a population decrease in their home country.There's a place for everyone in this world
Human beings are doing what human beings are designed to do.It's not down to anyone else ,let alone a government to tell you you have to sabotage what nature created perfect.Certainly the opinions of 29% of readers of one minor London newspaper do not reflect life in the real world for the most of the country.
Yes,I'm biased,I have 7 children at the moment and intend to have as many as I am given.These are babies we're talking about,potential human beings,not a plague.I have three friends my age who have no intention of and will never have children.They are not alone.There's a balance.
Population trends vary over time and doesn't need interfering with.
