Chemicals in southern California wastewater are sneaking past sewage-treatment plants and into the ocean, where they can seriously wack out fishy hormone levels, according to preliminary research. Flame retardants, PCBs, residue from long-banned pesticide DDT, and other chemicals from pills and beauty products have all showed up in the water, via human pee. An ongoing study of a flatfish called the hornyhead turbot (hee hee) finds that some males of the species have abnormally high levels of estrogen, while one hearty male had actually produced eggs. Activists urge that treatment plants be upgraded to catch more chemicals.

The city government of San Francisco is currently taking public comments on how to rebuild its old sewage system. The first choice is whether to continue with the one pipe system wherein rainwater drains into sewage pipes, causing discharge of less treated sewage during rains exceeding certain amounts. The upside is that all water gets at least some treatment under this method, but the downside is obviously discharging only partially treated sewage. (If runoff is not treated, it gets discharged as is, which includes motor oil, gasoline, pesticides, etc.) If a separate system were built for rainwater, that water would just be discharged without treatment with all the runoff pollutants. Additionally, water "treatment" is not some natural process, but is instead a chemical process that creates its own environmental and ecological problems, such as use of chlorine, which is highly toxic and very ecologically harmful, despite massive propaganda to the contrary that has obviously brainwashed the masses.
Conclusion: We need to greatly lower our population so that there are not massive amounts of human waste, and we need to live a lot more simply and naturally so that we use the waste or dispose of it in ecologically benign ways, such as septic tanks, which do not work with large populations.

It is not easy to see what is to be done, right away. Obviously, our numbers, plus the things we consume, plus the way we dispose of excess, intentionally or inadvertently, are a terrific ecological problem, with all kinds of bad consequences.

Water treatment not a natural process? Tell that to the aerobic and anaerobic bacteria that do 95% of the treatment.
