I honestly can't tell if that's supposed to be satire or not. Section 1 basically boils down to "Well, you live in the first world! Who cares if some farmers in Africa die from climate change? _Your_ kids will be fine!".

Besides that, all of the arguments that are presented seem to start from the perspective that having children should be the default. The author makes no claims that the world will be a better place for them, and therefore I see no reason why anyone would want to bring more suffering into the world, and cause more harm.
