this part about rain and ground cover! If you look at satellite imagery of spain, most patches resembling desert are those used by convential agriculture. And still they plow. There is no top soil loss, it's been washed away many years ago. This is plain erosion, the land is "melting" with each rain event.

Doing what little we can on our own plot or neighborhood has a big impact. So much life returns so quickly after adding some mulch and stopping to plow.

It's beautiful, makes sense and gives back so much.
