Any species that has to rely on its own excrement, solid or fluid, for its survival is no longer capable of sustaining itself at the growth rate at which it has become accustomed. Water Treatment is just a metaphor for the fact we have gone well beyond sustainable numbers.

In relation to that information, the link I’ve included is to a lecture on a mathematical proof of the population/carrying capacity relationship. The lecture is by Dr. Albert Bartlett of the University of Colorado at Boulder. Simple concept, grade-school math–anyone can figure the results.

The lecture is in 8 segments but the first 3 segments(roughly 25 minutes total) most aptly apply to the situation of growth in any area(the Boulder, Colorado/L.A. example is attention catching). By the way, he address SEWER Treatment Plant at the beginning of segment 2. You can do the math yourself and see how many DRINKING water treatment plants will be needed.

I hope this information can be useful. I’m just a concerned citizen. We face the same problems in Washington State, where I live.

Thanks for your time.
