Let me explain the physical laws of nature deal with things like, oh, they’re also chemical laws. But the physical laws of nature deal with things like the underground water systems and the theory of isostasy (coughs) which is, excuse me. The theory of isostasy is the physical movement of continents. How there’s adjustment. Some land is going up, some lands going down. And there are all kinds of pressures that change (clears throat) the positions of the continents and the whether the sea coast is being eroded or whether it’s being build up, things like that. We have to know about wetlands are incredibly important. That’s one of the physical laws of nature, that water is percolated and filtered through the wetlands, and that you have to have water in the underground water system.
