Save up to $100K through this Eco-lifestyle Adjustment

Slums constitute the living arrangement for one-fourth of today's world population. In the least developed countries, those living in slums exceed three-fourths of the population. Any urban area can descend quickly into slumdom when water and sewerage stop functioning. This can happen in any urban environment where the electric supply is lost for a week or where general mayhem prevails. Take Yemen, for instance. Facing a crisis of war, famine, and social collapse, 14 million people there lack access to safe drinking water or sanitation. The conditions are ripe for outbreaks of disease, which is currently appearing in the form of the most massive cholera epidemic this century. 

Cholera is spread by ingestion of Vibrio cholerae, which lives in the water where infected people have released sewage. If not quickly and properly treated, it can cause death in 50 to 60% of those infected. Currently, the number of cases in Yemen is 200,000 carriers of the bacteria. In the 2008 - 2009 Zimbabwe epidemic, the average infected individual transmitted the disease to 1.1 - 2.7 others. Those statistics are the reproduction rate (R0) of the disease. Predictions of 300,000 new cases in Yemen by August must use the lower of these rates.

It is conceivable that conditions in the U.S. could deteriorate to bring about local outbreaks of cholera or one of the other many diseases associated with lack of clean water and sanitation. Sewer systems are susceptible, but a heavy septic system load in a concentrated area could also become a major source. My own neighborhood is reputed to have 70% of its septic systems in a failed condition (my own included) with a 2000% overload to the watershed due to the concentration of homes. 

If you are one of the approximately one-third of homeowners in the U.S. with a septic system, it would behoove you financially to limit your inputs. The typical septic system fails after 15 to 30 years of service. Replacing it might cost up to $20,000 (not to mention the effect of heavy machinery on areas of your property you never planned for). Extending the life of a septic system by using biodegradable soaps and having the tank pumped every three to five years helps, but an unconventional measure that could allow your system to last a lifetime is to not use it for sewage, period. This simple lifestyle adjustment could save you $100,000 over a lifetime.

Loveable Loo - well worth the $400. Detailed instructions included. (An $18 economy unit also works fine.)

Instead of using your drinking water to flush away sewage, take up meticulous composting with your bodily byproducts. Joseph Jenkins tells you all about it in The Humanure Handbook. In the process, do everything necessary to avoid spreading of pathogens to your environment. Don't let your septic system get to the point that mine is, where it is a major health hazard. Humanure composting, even done half well, is better than this. 

Fortunately, when I found out that my septic system had failed, I was already well along with my humanure collection and composting program. With a little luck, I can restore my drain lines to the point that they will drain "greywater" for several more years and all of our sewage will go into the humanure toilets for composting with the biochar, coffee grounds, and small wood chips that I generously smother it with. If you think that sounds slummy, just wait until your community's water or electricity stops flowing.

Before Letting the GeNe Out of the Bottle...

Applying the Precautionary Principle to genetically modified organisms (GMOs), we support a moratorium until safety can be demonstrated by independent (non-corporate funded), long-term tests for food safety, genetic drift, resistance, soil health, effects on non-target organisms, and cumulative interactions. - Green Party Platform (Agriculture)
The Green Party would probably like to idle CRISPR until we better understand all of the ramifications of making changes to an organism's DNA, but its inventors have come out with a benign version that can be used just to detect a particular disease. It does this through matching RNA of the virus or other pathogen, typically from a blood, urine, or saliva sample. The fact that the new system, named SHERLOCK, can be impregnated into paper and stored there until needed makes it very cheap to produce by the millions for bedside detection of communicable diseases, cancers, and other urgent conditions. Each unique RNA sequence being checked (Zika virus, for instance) could have a SHERLOCK produced within a few days and it would be 1,000 times more sensitive to detecting the virus than the most common tool now in use (ELISA).

This looks like a biotech development that should sail through FDA approval and soon be in the hands of clinics worldwide. That will be a huge boon to the Broad Institute of MIT and its spinoffs, giving them and CRISPR great publicity and more of a chance of approval for wider application. Regulators and lawmakers should move quickly to set limits on genetic engineering. The extent to which the food industry has already taken liberties with biological pollution is disconcerting to many and now can be expected to accelerate unless authorities step in.

The Green Party  is calling for a federal Technology Assessment Office to examine how technology fits with life on Earth, with our neighborhoods, and with the quality of our daily lives. There was such an office for a short while until Congress decided they could politic just fine without looking into risks and unintended consequences. SHERLOCK looks like a wonderful tool to prevent diseases from spreading. While celebrating, let's make sure to look hard at CRISPR and other related technologies before we let that surge of optimism carry us away.

America's Weak Immune System

While weighing the possibilities of launching more Tomahawks on parts uncivilized, Blowhard has paid scant attention to a threat far more perilous than chemical weapons; even far more likely than a nuclear attack, but more deadly. That threat is from viruses in our environment that can mutate, spread, and multiply too quickly for us to respond if we are not organized and prepared. Once a virus is on a rampage, the result of unpreparedness could be millions of deaths in just a few weeks... for months on end.

Those viruses may seem to favor squalid and exotic places, but globalization, decay of our cities and towns, and wild changes in our climate make the U.S. a better breeding ground than we would care to admit. Neglect of the environment only increases the chances of a pandemic. Blowhard is not only guilty of such neglect, he is also failing to appoint officials who can prepare us for any outbreaks that do occur - indeed, he is calling for drastic budget cuts to agencies whose job it is to head off pandemics. Then again, this is a president who thinks that any domestic problem can be solved with a travel ban.

From Esporo
The world's most recent brush with widespread pestilence was the West African Ebola hemorrhagic fever outbreak in 2014. Blowhard was calling for travel bans - in this case, aimed at the medical heroes coming home from the front lines of the fight against Ebola. Any new viral threat would surely elicit executive orders for travel bans. Given Blowhard's craven germophobia, how many responders today would catch a one-way flight to head off that threat? Then, when the disease lands in the U.S. anyway, how many Blowharders would refuse to get their children vaccinated for fear of making them autistic?

America's retrenchment from globalism, while due, will have many drawbacks that leave us less capable of mustering global responses to problems such as pandemics, climate change, and feeding the hungry. There are several indicators that we won't be ready to respond effectively when the next virus outbreak occurs. This aspect of the America First doctrine may be tantamount to genocide by negligence.
