Did you remove the native flora?

There's your problem.

They did a lot more than that.

Frequent tillage, monocropping, the use of chemicals that killed the soil biology that let's plants actually grow.

And their erosion actually reduces the water holding/penetration capacity of the soil which means more erosion.

IIRC, Indiana was covered with forest before white people took over. There was also a giant swamp, the Great Black Swamp, in NW Ohio.

The Midwest has got to be one of the most thoroughly human remade landscapes in the world right now, so yeah, it's not gonna be like it was.

"Not this shiat again."

/ Say, we are about 100 years removed, about ripe for a rerun.

Iowa was just native prairie, very little woodland. But just swapping native grasses with corn (itself a grass) for a hundred years eroded something like 95% of the natural topsoil.

I bet we've barely scratched the surface of understanding how badly we've truly contaminated the groundwater--and the domino effect it had on the rest of the soil biome. There are probably entire classes of soil microbes that were once critical, we never really identified them, and now they are completely extinct.

If you want the common clay of the Midwest to care you have to talk about it in terms they understand:  Not only is Mexico taking your jobs, but their gulf is taking all your dirt.

Meh. Red states. They need no help. Market forces will fix it.

The entire eastern third of the USA was a hugely forested area until we built railroads and basically cut down every tree to fuel locomotives.

You're not like the other people in the trailer park, Stuart.

No, The Dust Bowl is NOT a PAC-12 football championship game.

I suppose considering the duration of habitation by agrarian cultures it deserves an honorable mention at least.

I know what's really going on. I know it's the queers. They're in it with the aliens! They're building landing strips for GAY MARTIANS! I swear to God.
