You don't know what's missing when it's already gone. It depends what area you are talking. The "Ozarks" could mean any number of areas. Sure, the deeply forested areas of southwestern Missouri and Arkansas still have a bit more diversity. That diversity is disappearing as people encroach. The invasive species are taking over. Pollinators have died off. Aquatic life is nil in places that teemed with life. A few frogs, snakes, lizards, toads, possums, raccoons, foxes here and there don't compare to what was here 30 years ago. I used to walk down a stream and just grab bait jumping or swimming around as I went. Literally thousands of frogs, crawdads, minnows, shad, snails, water spiders, spiders, snakes, lizards, toads, bugs, fish, salamanders, etc. not to mention all the other micro organisms. Pure, flat rock, worm eaten rock streams with crystal clear water and deep pools. It's dead by comparison now, filled in with gravel that can't support much life, or picked clean of rock by people to make money or put around their house. They have even been trying to put factory farms on the Buffalo River, a national treasure. Do I want to move 2 hours in the boonies to see more, and have better streams, sure, but hard to make a living there. I love the outdoors and I'm sad that future generations have less and less life to experience. My grandpa talked of jackrabbits and roadrunners and there are countless others I'm sure disappeared long ago.
