You can start by using the 300 acres of old coral reef in my back yard, at 4,000’ elevation.
Corals are some of the oldest critters still around, despite multi-hundred foot fluctuations of sea level; several degrees fluctuation up & down of sea temperatures, and MUCH HIGHER CO^2 concentrations during some eras.
Not only do the enviroes try to maintain that our climate is “optimum” and should be stabilized; they say the same about cliff erosion, beach formation; barrier islands, and every other aspect of nature that is in a constant state of flux and change.
They are worshipers of Darwinian evolution, but expect it to stop, now that it has reached the highest state of creation: THEM, and their pet areas.
What is lime? Is that not the deposits from an ocean?
Amazing how lime will neutralize acidity.
So you can actually mine the coral deposits? Are any hard enough to be the kind that they are decrying a loss in the Jewelry industry? The colors that can be polished up?
SD as in South Dakota, Yes? Guess the Indians got the coral from somewhere other than the South Pacific. Sounds like you have some interesting resources. Enjoy!
