But with talk of future space colonies and cities on Mars, there's a good chance that one day humans will give birth somewhere beyond Earth, and that brings up some interesting questions.

但说到未来火星上的太空殖民地和城市，人类有可能在未来某一天在地球以外的某个地方进行分娩，由此也将带来一些有意思的问题。

A space colony must withstand  the harsh conditions of space, but it must also create a safe and comfortable  environment for generations of human colonists.
