Ridge-Reef-Responsibility II In lieu of the more ecological conservationism themes of the previous lab trips, it seems that I can still continue with this ridge-to-reef preservation narrative. As rain falls, it brings whatever it catches down the hill into the stream with it. Whether it will be silt, nutrient-fixing bacteria, or biohazardous pathogens; if it gets caught in the stream, there is little to nothing that will stop it from reaching the water lens, sea level, and ultimately, the human population. In many tropical island nations, and many places that receive large amounts of rainfall, the freshwater lens and the surrounding reef downstream from affected streams are periodically threatened by contamination. The freshwater aquifer contained in the porous limestone geology of places like the northern half of Guam are susceptible to nasty pathogens found in animal feces, the chemicals and heavy metals of careless, illegal dumps, and other runoff from roads and automobiles...
