The American Prairie Reserve is planning to create a grassland reserve in Montana where 10,000 bison may roam.

MALTA, Mont. — On fields where cattle graze and wheat grows, a group of conservationists and millionaire donors are stitching together their dreams of an American Serengeti. Acre by acre, they are trying to build a new kind of national park, buying up old ranches to create a grassland reserve where 10,000 bison roam and fences are few.

The privately financed project — now a decade in the making — has ambitions as big as the Montana sky, tapping private fortunes to preserve the country’s open landscapes. Supporters see it as the last, best way to create wide-open public spaces in an era of budget cuts, government shutdowns and bitter battles between land developers and conservationists.
“It’s a once-in-a-lifetime opportunity,” said George E. Matelich, the chairman of the conservation group, American Prairie Reserve, and a managing director of a New York private equity firm. “It’s a project for America.”

Our Mission

EnviroFlight Aims to Lead Transformative Change in Our Global Food Supply
The world population is expected to increase from 7 to 9.3 billion in 2050. The 2012 Organisation for Economic Co-operation and Development (OECD) and the United Nation’s Food and Agricultural Organization (FAO) states that food production must increase by 60% in the next 40 years to meet the projected global demand.
The 2012 data on food and nutrition security worldwide reports that 870 million people are chronically undernourished. Moreover, 2013 data states that in 2008, more than 1.4 billion adults, 20 and older, were overweight.
FAO estimated yearly global quantitative food losses and waste at roughly 30% for cereals, 40-50% for root crops, fruits and vegetables, 20% for oilseeds, meat and dairy, and 30% for fish.
EnviroFlight’s mission is to develop sustainable animal and plant nutrients using regionally available, low-value materials, emphasizing:
  • Production of nutrients in a socially responsible way
  • Eliminate toxins, hormones, and antibiotics from our food supply
  • Reduce the environmental and financial costs to our food supply
“We produce the insect proteins to feed the fish, to feed the people.”

eBay and Craigslist Battle is now in Court

eBay and Craigslist Battle is now in Court

eBay and Craigslist Lawsuit
eBay and Craigslist Battle is now in Court
12/9/2009    by John
The battle between eBay and Craigslist has finally reached the courtroom. At issue is did eBay use the information it obtained by being on the Board of Craigslist to help it create a stronger competitor and should have Craigslist diluted eBay as a result.
Back in 2004 eBay paid $32 million for its stake in Craigslist. Of this sum $16 million to Philip Knowlton (a former employee) and $8 million each to Craigslist co-founder Craig Newmark and CEO Jim Buckmaster. In return eBay obtained 28.4% of Craigslist, a board seat and special rights that included an ability to block the issuance of new shares.
eBay created a competitor to Craigslist, Wijiji, and launched the site Internationally in 2005 and the US version in 2007.
The launch of the US site was kept from Craigslist despite concerns from the top eBay attorney. One of the eBay representatives how held the Board seat, Josh Silverman, went on to lead the International Classified business of eBay.
The lawsuit presently underway is specifically about whether Craigslist did wrong by issuing additional shares and diluting eBay to only owning 24.85% of Craigslist. A shareholding below 25% resulted in eBay losing their board seat.
great Wired Magazine article about the court case highlights the role of Meg Whitman who is hoping to become the next Governor of California.
The trial started on December 7, 2009 and is expected to feature the founders of both eBay and Craigslist.
Interesting times.

The Theory Behind Aquaponics

  • The Big Picture

    All energy for living organisms is ultimately derived from the sun.  Autotrophs using the sun's energy create organic molecules through photosynthesis (Calvin Cycle), and do not require exogenous (external) organic compounds.  Our fish food is made by autotrophs...and the produce from our gardens is made by autotrophs.  Heterotrophs derive energy by breaking down organic molecules made by plants (Krebs Cycle).  Humans, our fish, and the bacteria in our systems are heterotrophs...(sadly) we can't use the sun's energy and atomospheric gases to generate organic compounds.


    Autotrophs produce macromolecules in the following way:
    Specialized plant cells use glucose as energy to convert minerals and other atoms into cellulose, sugars, starches, organic acids, antioxidants, medicines, and plant fats & proteins. Cellulose, sugar, and starches are actually polymers of one chemical....glucose...only chained together differently.  Although any AP system should have basline levels of certain minerals, the types of plants will determine frequency of supplementation.  For example, systems that produce spinach will require more frequent additions of supplemental chelated (Kee-lay-ted) iron.

    Mineral supplementation is a hotly debated issue, with some asserting "as needed/symptomatic" dosing, "scheduled" dosing, pre-made commercial mixes, mineral+commercial base dosing, vermicompost "tea", using hydroponics concepts, NOT using hydroponics concepts....I'm confident that there is no one method that is perfect.  However, if certain practices provide results I'm sure it would be beneficial to learn from the failings/successes of others.  Entire books could be/have been written on this subject.  As I learn more I will add posts regarding mineral supplementation.

    Atoms plants need to build macromolecules (protein, fat, carbs) are necessary.  Cellulose = fiber...made from glucose but we can't digest it.  Sugars and starches = digestable forms of glucose.  See the formula above, that's all you need to make it.  Fats contain the same atoms as sugars:  oxygen, carbon, hydrogen.  Nothing extra needs to be added for formation of fats.  Proteins contain the same atoms as glucose, but ALSO need nitrogen and sometimes sulfur (miniscule amounts).  Nitrogen will come from your nitrates, and sulfur can be added directly to the system or via fish food.

    Another autotroph (but NOT a plant) evident in your system is algae.  A general rule is that if it's green, it uses chlorophyll, and is an autotroph.  Just like grass, if you remove light, it will die/subside.  If  you have alge in your growbed, add more growth media, shorten your stand pipe, or fill you tank under the growth media.  Most fish will eat aglae, so growth in the FT is desireable.  Also, snails eat algae...and fish eat snails, so it's a double whammy.  If you're using clear tubing and algae is clogging the tubes, cover it with foam tubing insulation, spray paint tubing, or replace with rigid PVC.


    Heterotrophs require organic molecules from other animals to power their cells and synthesize their biomass. 

    Bacteria. Oddly enough, the bacteria of interest in our AP systems are also heterotrophic. The difference is, rather than consuming the biomass of other lifeforms they consume the waste products of other lifeforms. Of primary concern is fish piss (or ours, for that fact). Primary contents of piss are water and urea, among other electrolytes. Healthy urine is sterile, and is necessary for nitration to occur.

    Here is a graphic illustrating how you, me, the worms, and the fish process the products of autotrophs to make ATP, which powers our specialized cells to synthesize muscle, nerve, guts, and/or bone.

    Worms.  The next tier of animal complexity is the red worm.  This guy is a major contributor to the system in that he breaks down organic solids, such as insoluble fish waste and vegetation, into soluble matter that the plants can readily absorb. It's important to pay particular attention to these guys because they will actually decrease your need to add much commercial nutrient and supplementation.  In grow beds, they are placed direcly into the growth media, along with vegetation and compost from the kitchen.  Another way of using worms is through vermicomposting.  However, composting requires a higher degree of nutrient, moisture, and temperature control to be optimally effective.

    Fish.  The fish are, by far, the most complex heterotrophs in the system. Without the fish, you would have to pour chemicals or piss and crap into the system to get it to work, which is pretty unhealthy for vegetation consumption.  Remember all of the spinach/e. coli recalls in the news? All are the result of using the manure of warm-blooded animals...which is avoided using fish manure.  In an AP system, these animals require oxygenated water, water filtration, fish food, pH control, and temperature control.  Beyond this, they don't require much, and a well-designed system can correct for the almost all of these factors:
    - Venturi aeration solves oxygnation.
    - Grow beds solve water filtration.
    - Inulated tanks and environmental controls solve temperature control.
    - Commercial base solves pH.
    - Commerical fish pellets solve fish food.

    Stay tuned. More to follow.

  • It’s all about water

    Acid and base chemistry has its roots in the actions of water.  Water (H2O) does not solely exist as H2O as it sits in a glass on a table, but rather splits into its ionic (charged) parts.  H-OH breaks into H+ and OH-.  H+ is a hungry proton, looking for another compound to attack to balance its positive charge and become neutral.  This is what makes acid “acidic”, and why hydrochloric acid (HCl) will eat your flesh…it’s all about those hungry H+’s looking to balance their “+” charge.  Similarly, OH- is a hungry hydroxide looking to balance its charge by attacking other compounds.  This is what makes bases “basic”, and why lye will eat your flesh…it’s all about those hungry OH-‘s looking to balance their “-” charges.

    How water is the acid

    Let’s say your fish tank is full of water sitting at room temperature.  Some water will remain as H2O molecules, while some dissociate (split) into H+ and OH- ions.

    Let’s add 4 parts hydrochloric acid (HCl) to the water.  Acid will also dissociate into H+ and Cl- ions.

    The hungry H+’s from HCl will attack the OH-‘s in the water, turning them back into H2O.

    Since 4 OH-‘s are removed from the solution, we now have an excess of H+.  Thus, by HCl making H2O less basic…it becomes more acidic. Our extra choride ions are just floating around, doing nothing as spectator ions. 

    How water is the base

    Now, let’s add 4 parts ammonia (NH3) to the original neutral water in the fish tank.  Ammonia is uncharged, so it dissolves but doesn’t dissociate in water.  However, nitrogen is famous for having an extra pair of electrons (negative charges) that are hungry for positively charged species.

    The hungry electrons on ammonia (NH3) will steal 4 H+’s from the water, turning it into the positively charged species ammonium ion (NH4+).  Since 4 H’s are removed from solution, we have an excess of OH-‘s.  Thus, by ammonia making H2O less acidic…it becomes more basic.

    Where does pH come into play?

    pH is based on logarithms.  Specifically, it is the negative log of H+ concentration.  The pH scale only goes from 0-14.  There is nothing more or less.

    If concentration of H+ is 10-14 in a solution, that means its concentration is 0.00000000000001.  This is a VERY weak acid.  Calculate -log(10-14) = pH of 14.  This VERY basic because not much acid.

    If concentration of H+ is 10-7 in a solution, that means its concentration is 0.0000001.  Calculate -log(10-7) = pH of 7.  This is neutral, like pure water.

    If concentration of H+ is 10-1 in a solution, that means its concentration is 0.1.  Compared to 10-14, this is a VERY strong acid.  Calculate -log (10-1) = pH of 1.  This is VERY acidic. 

    So why bother using pH at all?  Consider this:  An H+ concentration of 10-1 is 0.1.  An H+ concentration of 10-7 is 0.0000001, which is 1,000,000 times LESS than 10-1.  Rather than making it difficult for the layman with calculating exponents and logarithms, pH makes things easy by saying pH 1 and pH 7.  Let’s recap:

    Acid = LOW pH (below 7)

    Base = HIGH pH (above 7)
