Old MacDonald had a farm…
And apparently so does Hollywood.
Mother Nature Network’s (MNN) blog often talks about green celebrities,
lifestyles and culture. They have several stories on celebrity farmers. As food
becomes more expensive, and habitats being destroyed for industrial farms
around the world, organic, local farms are becoming more popular. Here is a closer
look.
Oprah Winfrey is
producing 145 pounds of produce a week on her land in Hawaii. What started out
as an experiment will be turning into a business very soon. Oprah and Bob Greene (one of her health guru’s)
realized that almost 90% of all island food is flown or shipped in, making it
very expensive and leaves a large environmental foot print. They decided to try
to grow their own food and share it locally.
Right now, according to MNN, she gives the food away, but
that will soon change as they get more involved in the process (MNN, 2013). Follow the
link to read the whole story.
Dylan Ratigan, an MSNBC
anchor gave up his career to become a farmer. He relocated to Southern
California to go into the farming business with a former marine, Colin
Archipley, to start a network of hydroponic greenhouses that will be aimed at
employing veterans. “Their mission has a double agenda: to operate a successful
small-scale organic farm and also help soldiers make the transition from war to
agriculture ... and financial independence” (Breyer,
2013).
James Cameron has
two very successful biodynamic farms. He owns over 4,000 acres of farm land in
New Zealand; and now has an over 100 acre home in Los Angeles, that is turning out
to be quite impressive. This farm provides roughly 90 percent of the food for
the family. He hired consultants and the crops are grown in accordance with the
phases of the moon.
Cameron stated that after he and his wife saw the documentary
“Forks over knives”, they completely switched to embrace a vegan lifestyle (MNN,
2013).
To watch forks over knives (which the library owns), consult

Here is an article to get you started…on what biodynamic farming
is and how it benefits the planet.

Batta, batta, SWING, batta!
Human throwing ability vs. the chimp
Can a chimp
throw the same as a human? Researcher, Neil Roach, at George Washington
University decided to find out. He found that humans are unique in throwing
ability, even when compared to chimps.
Chimps are
very athletic, but can only throw one-third the speed of a 12 yr. old little
league pitcher. Human ability to throw evolved nearly 2 million years ago to
aid in hunting.
Their study
recorded throwing motions of collegiate baseball players, finding the shoulder
acts a lot like a slingshot during a throw, storing elastic energy and
generating fast forward motion.
Applications for the study may help
athletes and injury. Those athletes throw more than our ancestors did, and consequently can end
up with injury (Science Daily, 2013).
There is a more in depth look at the biomechanics of pitching on the Human Kinetics website here.
You can read
a short summary article in science daily (see link below) or read the entire article
listed in the references. Students don’t forget you can research sports or
injury biomechanics and many other topics from our online databases.

How ‘bout a hug?
Scientific validation for hugging trees
image credit Uplift, 2013.
You have all heard the term, tree hugger to describe
environmentalists, hippies and other nature conscious groups. Well, turns out
that there is now scientific evidence to support health benefits from hugging
trees. You don’t even have to actually touch a tree to benefit from it; you
just have to stand close to it.
The editors at Uplift recently published an article
reviewing the book Blinded by Science,
by Matthew Silverstone. The book states that tree hugging has many health
benefits and can improve “Attention Deficit Hyperactivity Disorder (ADHD),
concentration levels, reaction times, depression and other forms of mental
illness. He even points to research indicating a tree's ability to alleviate
headaches in humans seeking relief by communing with trees” (Uplift, 2013).
Research also indicates that children’s cognitive and
emotion functions improve with play in green areas. Up until now, it was the
open green spaces thought to be the contributing factor for these benefits. It
is now shown that the actual trees and plants are beneficial because they all
vibrate. These various vibrations affect biological behaviors.

Saving the European Bison
The European bison (Bison
bonasus), also known as the wisent, is the largest herbivore in Europe.
Historically, the Bison bonasus was
distributed widely throughout Europe. At the end of the 19th
century, the wild European bison (Bison
bonasus) herds were reduced to two populations; Bialowieza Forest (B. b. bonasus) in Poland and in the
western Caucasus Mountains (B. b. caucasicus)[LHN, 2012]. According to Pucek (2004),
the initial decline of the wild bison was due to an over-population of deer
species and drastic reductions of natural food sources. The onset of World War
I and poaching were the final causes for extinction of the European Bison (Bison bonasus) in the wild. At the time
of extinction of wild bison, the captive population consisted of 54 individuals
(29 males and 24 females; with 12 founder animals)[LHN, 2012]. In 1923, Polish
zoologist, J. Sztoleman introduced the idea of restoring wild populations of
the European bison (Bison bonasus)
from captive stocks housed in zoos. Later that year the International Society
for Protection of European Bison (Bison
bonasus) was founded in Germany (Pucek, 2004).
Summary of reintroduction programs
The first reintroduction program of the
European Bison (Bison bonasus) [from
captive populations] began in 1952 (Pucek, 2004) in the Bialowieza Primeval forest
(BPF) in Poland. Efforts resulted in the establishment of a single breeding
population. Following this initial success, additional herds were established
in other areas of Poland, Lithuania, Belarus, Ukraine, Russia & Kyrgyzstan;
resulting in a total of 30 free ranging herds (Pucek, 2004).
Protection of genetic purity was aided by the European Bison
Pedigree Book (EBPB) that had been created in 1932. All crossbred animals were
eliminated from the breeding cycles of the pure genetic lines of bison. The
EBPB is still in use today and every individual born worldwide is entered in
the book. The reintroduction program began with intensive captive breeding
programs in zoos and reserves from a founder stock of 12 individuals.
Contemporary herds are now separated into two distinct genetic lines (Olech
& Perzanowski, 2002). The second phase of the reintroduction began producing
free ranging herds in natural habitat areas. The total global number of
European bison (Bison bonasus) is
approximately 2,900 (1,700 free or semi-free)[Pucek, 2004].
Since inception of the bison reintroduction program in 1952,
staff at the BPF has been monitoring the free range bison populations (i.e.
size, sex and age structure; recruitment; mortality)[Mysterud, et al. 2007]. Population dynamics
analyzed by Mysterud, et al. on the
BPF bison population [from data collected between 1952-2000] report that
recruitment for the entire time frame yielded 741 males and 770 females
resulting in nearly a 50:50 ratio. Analysis of the herd did not find any impact
on recruitment pertaining to climate variations; however mortality rates were
found to be higher in cold winters, as well as lowered reproduction rates
(Mysterud, et al., 2007).
Habitat preservation is essential to the success of
reintroduction of the European bison. The BPF is one of the best protected deciduous lowland forests in Europe
(Mysterud, et al. 2007). Currently
the bison are dispersed globally in 30 countries. Studies conducted by
Kuemmerle, et al. (2011) indicate there
is suitable widespread habitat that is currently unoccupied in Central and
Eastern Europe. Viable population increases are not limited by habitat accessibility.
