All animals produce CO2 just by breathing. Should we cull their populations? Sterilise the largest mammal species so they can become extinct? To revert global warming, the breathing of animals such as ourselves is rounding error. Furthermore, reducing population is only useful to the extent that the population is assumed to have a carbon footprint (breathing excluded) which is still unsustainable as is that of the current population. It is a measure that can have an effect on the macro policy level of "promote the conditions that will encourage demographic transition" [0], not on the micro "don't have kids" scale. Honestly, the idea that having kids is irresponsible because "population growth causes global warming" is a prime example of an infantile idea.
