I think as a society we need to get away from sappy Hallmark channel stuff like this and celebrate the individual. We should not be made to feel like having kids is some transcendental thing.
Studies consistently show childless people are happiest irrespective of age. Parenthood is just a thing to do, nothing more. There's no need to make people believe they want to have kids when it will more likely decrease their happiness, and definitely increase co2.
