Tragedy of the Commons
In December 1968, a scientist by the name of Dr. Garrett Harden coined the concept called the “Tragedy of the Commons” in his article of the same name published by Science Magazine. “The Tragedy of the Commons” is a problem that occurs when a resource –such as the ocean, water, and air- is open to everyone. The following video clips will help you apply your experience from today's "Happy Fishing" activity to the concept of “Tragedy of the Commons”. The goal of this blog assignment is to help you understand the difficulties associated with managing shared resources.
Assignment: Watch the following video clips and write a one-paragraph (minimum) summary for each clip (Chalk Talk 1 & 2 count as one clip; so, three paragraphs total). On the top-right corner of a piece of looseleaf paper write your name, the class, the period, and the date. On the top-left corner write the name of this assignment "Tragedy of the Commons- Blog Assignment". Due Friday Sept. 4th

Using Camera Traps to Protect Big Cats and Their Habitat
Biological conservation researchers have increasingly
found camera traps to be a useful tool in collecting data on elusive species of
interest. A camera trap is not a
physical trap; rather it is a camera set up, usually on a tree in a remote area
where a species of interest is believed to exist. Animal body heat activates an infrared sensor
that triggers the camera to take a picture of the animal when it is near (WWF Camera Traps, 2015). Members of Felidae, the cat family, are a
particularly troublesome group of animals on which to collect data. This is due to an interplay of factors such as
large home range, mysterious behavior, and low population density to name a few
(Silver et al., 2004). The World Wildlife fund reports that camera
traps have been used in Indonesia to gain a greater understanding of tigers;
their behavior and specific threats to their survival as a species (WWF Camera Traps, 2015). Watch the embedded YouTube-World Wildlife Fund video clips below to get an idea of the type of footage that camera traps have captured.
In 2013 biological researchers Maputla,
Chimimba, & Ferreira used camera traps to conduct a mark recapture population
survey of the leopard population in Kruger National Park, South Africa. These researchers cited that camera traps
were appropriate for surveying leopards because of their mysterious and
independent behaviors, which make them hard to find (Maputla, Chimimba, &
Ferreira, 2013). Using camera traps, the
team estimated that there were nineteen leopards within a 150 km2 area of Kruger National Park (Maputla,
Chimimba, & Ferreira, 2013). Maputla,
Chimimba, Ferreira (2013) discussed several challenges to the precision of
their population estimates using camera traps; resulting in “unequal
catchability”. Some of these challenges
were: the cameras were too far apart and the camera placements were biased to
preferred paths of male leopards Park (Maputla, Chimimba, & Ferreira,
2013). Finally, Maputla, Chimimba,
Ferreira (2013) stated that similar research on tigers suggest that they had
the inclination to avoid the camera locations.
Another team of researchers, Silver, Ostro, Marsh, Maffei, Noss, Kelly,
& Ayala (2004) used
camera traps to conduct a mark recapture abundance estimation of populations of
jaguars in the forest of Belize and Bolivia.
Using camera traps, the Silver et al research team (2004) was able to estimate population
densities of jaguars in these areas to be between 2.4 and 8.8 per 100 km2. Silver et al explain that using camera traps
for estimating population density provides precious data that conservation
managers can use to make decisions pertaining to minimum viable population
sizes and habitat/range estimates that can be used to support and justify
conservation arguments in efforts to allot more protected areas for Jaguars (Silver et
al., 2004).
A topic of interest to me
is environmental degradation due to mining for sulfide oar. Camera traps are being used to provide
justification for protecting wilderness in the Santa Rita Mountains southeast
of Tucson, Arizona. This is the location
of a proposed Rosemont Copper Mine site. In 2013 Tony Davis of the Arizona Daily Star
reported that camera traps, set up by the U.S. Fish and Wildlife Service, took
five photos of a Jaguar roaming in an that has been federally proposed as critical
habitat for the endangered jaguar (Davis, 2013). The photos provide evidence of the existence
of this endangered species and help to propel the U.S. Fish and Wildlife Service’s
argument that the Rosemont Copper Mine site is “likely to adversely affect
the jaguar” (Davis, 2013). Camera Traps have great potential to provide invaluable data and indisputable evidence to justify protection of big cats and their habitat.

Global Warming's Canary in the Coal Mine
In the early days of deep coal mining, miners
would take a caged bird, often a Canary, into the tunnels with them.
Wiktionary explains the reasoning behind this: "If dangerous gases
such as methane or carbon monoxide leaked into the mine, the gases would kill
the canary before killing the miners, thus providing a warning to exit the
tunnels immediately." Furthermore, when people use the phrase "the
canary in the coal mine" they are suggesting "something which warns
of the coming of greater danger or trouble by a deterioration in its health or
welfare". ("canary in a coal mine ") When it comes
to global climate change, glaciers serve as a “canary in the coal mine” or in
other words an indicator that global climate change is occurring.
Glaciers, the world’s frozen reservoirs of
water, are shrinking. The basic concept is that as the Earth’s
temperature continues to increase, due increased human produced greenhouse gas
emissions (see Figure 1), the glaciers melt faster than they can accumulate
water, ice, and snow. The Union of Concerned Scientists (UCS) contends
that: “The volume of ice in a glacier and correspondingly its surface area,
thickness, and length is determined by the balance between inputs (accumulation
of snow and ice) and outputs (melting and calving)” (“Early Warning Signs”). How
much are the world’s glaciers shrinking? The UCS's online article
provides this example: “Since 1850 the glaciers of the European Alps have lost
about 30 to 40% of their surface area and about half of their volume.” (“Early
Warning Signs”).

“Mountain regions cover
approximately 25% of the Earths’ land surface and source between 60% and 80% of
Earths’ fresh water. All of Earths rivers have their headwaters and origins in
them. They are also known as the ‘Water Towers’ of the world. They provide
critical storage of fresh water in the form of glaciers, ice and snow. Many
streams and rivers would cease to flow entirely if their headwaters and
watersheds were not fed by the seasonal melting of these snows. Such valuable
storage of fresh water is vital for all life on Earth. However nowadays
glaciers and mountain snows are retreating, shrinking and thinning rapidly in
all regions of world, threatening the fresh water and food supply for
all.” (Joy, and Joy)
The fact that the Earth's glaciers are
shrinking surely "warns of the coming of greater danger or
trouble". ("canary in a coal mine ") That trouble or
danger is the threat of losing the source of 60% of the Earth's fresh water
supply. Currently, there are a handful of organizations that are
dedicated to research, conservation, and awareness of the condition of the
remaining mountain glaciers. One such organization is the American
Climber Science Program
(ACSP). Because mountainous regions,
particularly glaciers, can be treacherous, the ACSP combines groups of
experienced mountain climbers with climate scientists for a series of annual
research expeditions. As it is stated on
the American Climber Science Program webpage,
“The ACSP works
to link scientists and climbers to help provide the knowledge necessary to
preserve the alpine environment.” ("Empowering Climber Scientists") More information on
