There are occasional stories of this tone for different kinds of terrain: boreal forest, savannah, woodlands, wetlands and so on.

We need a cheap fast way to turn vacant or underutilized commercial property into carbon sinks. Like some way to fill up an empty parking lot at an empty office park or strip mall with portable self-watering containers that contain something like grass or bamboo or de-THC hemp. No need to re-zone anything, just roll up with it while the land is not being used, soak up some carbon, and then move on if the land gets used again.
