Green and Brown water floweth

The water in Western Samoa is crystal blue with touches of green. The water in the Columbia River is a brownish color that is most definitely not clear. My friend says that in the future big money will be made in (keeping) water clean. BIG money. I believe her. I wonder where the brown water stops and the crystal blue water begins, and how fast the brown water is eating the blue water. We humans are f$%^#$& this earth, slowly. The big fires, floods, tornadoes are only the beginning. I think it will get worse. The area where I live is waiting for a big wave (to smash all the beach houses to bit and pieces and nothingness). I miss the crystal blue.
