I mean, you'd lose most of the Appalachian Mountains which as one of the oldest mountain ranges in the world means losing a ton of ancient fossils that helped piece together the biological history of Earth. I'd also be curious how the glaciers would be impacted given how heavily they shaped much of North America
You also lose several major cities including Toronto and St Louis, Canada loses most of its habitable land (assuming the climate isn't significantly impacted by the existence of a second Mediterranean Sea, which it definitely would be) Chicago is going to be quite different but probably an even more important port city in such a world. Las Vegas is now a port city, so probably less casinos and more just major city. My wife would be sad because the Quad Cities (a metro area on the Iowa/Illinois border) wouldn't exist and she really likes that area. I'd be sad because the Mississippi River would be much short and therefore way less cool. But it's a really wild concept that gets crazier the more you think about it


I setup my wife's old Android phone to be super locked down via parental controls. Only approved apps, no installing apps, time limited etc. set it up so my kids can use it on days when we need them to zombify for a bit in the afternoons
Its kinda mind blowing how YouTube Kids is their go to and they don't move to any other apps until they've run out of time on it (family had already let the cat out of the bag about the existence of YouTube so I had to limit rather than block) and we still have had to block a number of concerning channels they kept watching. Its crazy how they'll just zombify staring at YouTube but then for the age appropriate games they're so much more engaged and actually seem to have a healthier interaction. Its also sad how some of the content I see the kids watching on YouTube Kids has writing and direction about on par with Disney's current crop of age appropriate shoes for 3-6 year olds (and from what I've seen Nickelodeon isn't much better right now). My kids primarily watch PBS Kids and a handful of shows we carefully selected on DVD because we want to minimize the brain rot (as well as minimize annoyance for us)
