Not having children because of climate change is irrational.

So, not having children purely due to climate change is irrational. Here are the reasons why:

• Climate change does not impact, for better or worse, the individual responsibility being a parent requires. Climate change, whenever it affects us or does or does not happen , is on a society / world scale. Parenthood is on a very local, adjacent scale. If your baby is hungry or needs milk, climate change doesn't change the requirements needed to raise that baby.
• One's childhood is largely determined by ones parents and how they are raised. Regardless of temperature outside, there are children that have good parents in the hottest and coldest parts of the world. Just like with the pandemic, the people that suffered the most were those in abusive relationships (locked inside, can't go out), while the people who did the best were those in loving relationships and families. In the event climate change did begin to majorly change society, the same would be true then.

Aside from the above two, I find that people claim to be child free due to climate change still go on trips frequently via flying , and generally are not trying to cut their carbon emissions much anyways. So it seems like a status symbol more than anything.
