This article points out how ecologically immoral and unsustainable overpopulated, modern industrial society is.  Below is an example to show that anywhere near this many people cannot live in a manner that's ecologically or environmentally friendly, nor can we do so by using technology, which is ecologically and environmentally harmful.

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.

Good points, Wolverine.

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.

Get rid of cities. That is Wolverine's solution and is the only way to return to septic tanks for sewage treatment. Next tell us how we should proceed to "greatly reduce" the population.

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

Tilt.

Do you propose shooting them or just starving them to death? Oh, maybe mandatory abortions -that is a democrat party plank, isn't it? Wait, that wouldn't be quick enough.

Since support for mass executions seems unlikely, despite the anti-human bias of this crowd, we will just have to rely on technology to solve the problems of pollution.  But wait, we will stop the advance of technology as we leave the cities, with their Enterprise, Universities and R&D centers, for the simpler life on the land. Of course, then most will die off due to starvation.  Problem solved!    

Providing proper birth control education in schools and free, completely unrestricted access to abortion for everyone would do a great deal to lower human population.  Fully fifty percent of pregnancies are accidental.  Empowerment of women is another thing that needs to be done, because the vast majority of women do not want large families.  Finally, a strong one-child family policy, with both carrots and sticks, would convince most people to limit their families.

Dan Detroit, what the hell are you talking about?
