This is a contentious issue recently given the rise of environmental awareness corresponding with overpopulation and the economy.

In China there is already an example of this kind of policy: the One Child Policy, introduced to curb overpopulation in 1979. Estimates have it that without this policy, China's population would be 300-400 million higher than what it is today.

In a world where you can't jump on a plane without cries of "think about the carbon emissions!" is this something other countries should look to adopt?

Or is it immoral for governments to intrude on family life?
