The $68k Fish: The future of salmon in the Pacific Northwest
> Biologists determined that not one of them was hatchery-born—they were all wild fish, whose robust natural paternity and hardy stream upbringing had given them a distinct advantage in surviving the return trip to Idaho. The hatchery fish were weaker, raised in tubs and selected from a narrow genetic slice that lowered their adaptability to a changing climate. Even though they outnumbered the natural-born salmon by millions, the failure rate in this case was so high that the vast sums of money spent in upper Idaho had not purchased a single hatchery success.That's a pretty good metaphor for the cost of coddling our children that Jonathan Haidt goes on about. By valuing our offsprings' safety so highly we're effectively raising hatchlings in tubs, as opposed to wild fish gifted with a hardy stream upbringing.
