You're not wrong. If one can't afford, then it's just not an option, and I agree it's probably not going to be good for anyone to have a kid in that scenario (whether making a baby or adopting).

That's not what the article is about though. Yes, technically it's not about empathetic people either, but in that case I've assumed that people who want to save the planet are likely to be empathetic (they think & care about their surroundings). I don't think that's too far-fetched.

If you were in a situation where things were affordable, would you get a car?
