I am a water
droplet, two Hydrogen atoms and one Oxygen atom covalently bonded
together. There are many pathways I may
take in life, but a particularly winding one is found along the Colorado River. My family and I began forming the Colorado
river valley about 6 billion years ago and in no time we carved our way through
seven states, formed the Grand Canyon, and worked our way to the Sea of
Cortex. Five trillion gallons of water
rage down this river today; few make it to the end of the river (Zielinski, 2010). With today’s new technologies, it is an even more
rare occasion for one of us to make it to the ocean, but I will get to that
later.
My journey
starts in La Poudre Pass Lake, high up in the Rocky Mountains. From there I begin my journey downhill into
the Colorado River valley. I must pass
through many dams and lakes (both naturally formed and manmade). These dams are formed in order to divert
water toward farmland, large-scale agro-business, and the municipalities of the
area (usbr, 2014). In the past, this was
not an issue; there was plenty of water to go around! However, with increasing population size and
settlement in the southwest, it’s becoming nearly impossible to provide water
for everything and everyone. This has
led to a lot of conflict throughout history.
There are
numerous decrees, laws, contracts, and guidelines about where water from the
river is allocated. There are so many,
in fact, that the Colorado is actually nicknamed “The River of Law.” These laws began with the Colorado River
compact of 1922, which stated how the water would be managed upstream so as to
allow for water use in the downstream states as well. Needless to say, throughout history there
were more law disputes between states than I can count, but today, once my
water friends and I reach Lake Mead, our rations are as followed (usbr, 2011): 1.5
million acre-feet (MAF) of water it to go Mexico; 4.4 MAF to California; 2.8
MAF to Arizona; and 0.3 MAF to Nevada. Along
with this, about 0.6 MAF of the water in the river returns to the atmosphere
through evaporation (Jacobsen, 2014). So,
as you can see, I have the opportunity to travel all around the southwest! However, the problem with this is that right
now the river is being overdrawn by about 1.2 MAF. This means that if there is not a change in
water usage in the southwest soon, the river will simply run out of water
(mid-west here I come)!
Like I mentioned
before, I have the opportunity to visit many different states. I may end up in someone’s shower, in the community
pool, or even a fountain in Las Vegas!
However, it is more likely that I end up going to work on a farm. About 70% of the Colorado River, after reaching
Lake Mead, goes toward agriculture. About
two-thirds go toward irrigation of big crops like corn, wheat, and soy. The other one-third goes toward the beef industry,
which means there’s a one-in-three chance I will be made into a hamburger
(Jacobsen, 2014). While this does sound
like a very exciting ride, it does present some problems.
The further
south I descend, the more contaminants I carry along. As humans’ population is rising and energy
needs are increasing, businesses have begun competing with one another to
extract resources found underneath the river basin. Uranium, oil, natural gas, and oil shale are
being mined and accidentally leaking harmful elements into my water path
(Deacon, 1999). The competition results
in companies putting minimum effort towards environmental safety measures. Also, runoff from farms leaks into streams
and groundwater, bringing along with it carcinogens from chemical fertilizers,
growth hormones, pesticides, and livestock manure. If these contaminants get out of control,
humans are in big trouble! They rely so highly on my water friends and I in the
Colorado River that if unhealthy contaminants appear in large amounts, they
would have widespread detrimental effects everywhere the water is distributed.
Humans have some
opportunities to help me, though! There
are several changes that can be made.
One is the potential use of deionization to purify saltwater, so less
freshwater would need to be taken from the Colorado River. This is the process of removing salts from
water. Unfortunately, it is very
expensive and not very energy efficient (Anderson, 2013). Hopefully, we can rely on technology
advancements to introduce more efficient, less expensive ways of using the
Earth’s massive supply of saltwater, but that hasn’t happened quite yet.
They could
change traditional agriculture methods to indoor hydroponic farming, which can
use just 10% water to grow the same amount of produce (Bradley, 2001). Hydroponic farming is being called the future
of agriculture for a reason; there are many pros and very few cons, and methods
are being constantly updated for energy and cost efficiency! Hydroponic farming is a method that uses just
water and a media of some sort to hold plant roots instead of soil, so precious
water is not wasted by seeping through the soil or evaporation, but instead it
is collected and reused while retaining its added nutrients for the plants!
Using the vertical method, lots of space is saved on an indoor farm than was in
the past, and the environment can be controlled to maximize temperature, carbon
dioxide levels, humidity, and light.
Along with this indoor environment control, pests are not involved as
easily so hardly any additional chemicals are needed! Thank goodness—those
chemicals were dangerous for my water friends and I as they kept following us
around through the environments and into foods humans grow. Also, LED (light emitting diode) lamps can be
used, which produce only the red, blue, and green lights necessary for plant
growth without wasting energy on all the other spectrum colors. Farms can be placed in the middle of cities
or areas of drought so that more people—especially those in the lower class or
those victim to food desserts—can access fresh produce at low costs and
transportation is cut down. Although
there is still electricity required, people can use other environmentally
friendly systems to produce all the energy needed, such as large-scale
composting systems and solar panels. Not
all plants can be grown efficiently hydroponically; tall growing wheat and corn
are better left to the fields. But leafy
greens, tomatoes, potatoes, and other smaller fruits, veggies, and herbs that
are grown in places like California, which is currently going through a huge
drought that will only become worse with global warming, can be moved
elsewhere. Perhaps Detroit, for example,
can grow vegetables with the plentiful freshwater found in the Great Lakes
rather than the endangered CO River!
The ideal side
of using hydroponic gardening is controversial with those humans. After all, traditional agriculture is natural
and beautiful, right? Why should they always rely on technology to come up with
a fix for their own destruction of the environment and consequential
issues? However, sometimes—as with the
case of indoor farming—the technologic alternative to environmental processes
is the best route in order to conserve
the environment for the future. The only
problem is balancing out the economy, seeing as Americans rely on a Capitalist
economy and the “growth machine” in order to keep itself stable, and farms
currently make up a huge portion of the country’s economy, but that’s a
separate issue altogether.
So far, it has
been clear that my journey has mostly had to do with humans. This is likely due to the ideology of
environmental domination- meaning human believe they have the right to control
the environment (Bell, 2012). Americans
have such an individualistic viewpoint of life that they rarely take the time
to notice the impact they are having on the river. People seem to think that our only reason for
existence is to slave away day in and day out making food, looking pretty, and
providing other services. But, I have a
different dream for my journey. I would
like to travel all the way to the ocean and see all the amazing plants and
animals along the way! Unfortunately, at
this point in time a dry and cracked riverbed is all I have to look forward to
at the end of my long road. Of the 5
trillion gallons of water in the Colorado River, zero make it to the ocean. About 100 miles prior to the sea, the water
simply stops. This had led to ecological
degradation, causing the delta’s population of birds, trees, and other animals
to dwindle. Currently, only 10% of the Colorado’s original wetlands are in
existence (nasa, 2014).
But, what would happen if I were able to continue on? Ecologists wondered this same question, and just last year set out to answer it. They cracked opened the Morelos Dam and let some water run through. What happened afterwards was amazing! The river came back to life! Insects that had been waiting years for this opportunity finally hatched, willow and cottonwood trees began to grow, and a new ecosystem showed signs of forming. The humans seemed pretty excited as well… the surrounding communities broke out in celebration for the return of their beloved river (Jacobsen, 2014)! It seemed that both the environmental and social impacts were great; maybe we are more connected than we think.

Unfortunately,
like all experiments, this project had to come to an end. The river once again stops 100 miles short of
the ocean, the land has returned to its desolate state, and the people have
resumed their typical lives in the desert.
Does this mean that this whole project was a failure? What is to come from the results? That I cannot tell, but I can say, we
remember. We remember what it was like
to flow through a lush oasis through the southwest. We remember reaching communities who do not
currently have the wealth and legislation to have a river. We remember, and as this project shows, the
river does not forget.
