Blog Reflections Blog #4

Question #1: What role, if any, should zoo's play in conservation and education?

     I believe that zoo's do exist as a place to preserve and protect some animals, and play a part in educating youth and adults on the issues surrounding wildlife.  However, I also feel that zoo's do not accommodate all of the animals that might live there.  I feel as though keeping animals in captivity is not fair to the true nature of the animal.  Zoo's can act to help a threatened species, but I feel as though this can hinder the animal if it was to be released back into the wild. 

Question #2: Is it ethical to keep animals in zoos?  If so, what size or type of animal or zoo?

     I do not believe that it is ethical to keep animals in zoos.  It is not fair to keep an animal caged, and deprived of its natural lifestyle.  I believe that the natural instincts of animals can be lost when they are kept in captivity.  Instincts, such as hunting skills, and basic protection against predators.  Since animals are not exposed to a natural ecosystem they lose the functions.  I do not think that any animal, big or small, belongs at a zoo. 

Question #3: Do you enjoy visiting zoos?

     I can honestly say that I am not a fan of the zoo.  It might be interesting to see the animals in person, but they are not immersed in their natural habitat so it defeats the purpose of seeing how the animal might behave.  It is sad to see animals in small quarters, yelled at all day, and put on display for large crowds.  I would much rather go out into nature and experience animals in their natural environments, this way I can gain a true sense of the animals and their surroundings.

Other Comments

      I really enjoyed taking this course.  I found the topics that we covered to be interesting and insightful.  I thought that the vocabulary terms given out were a great way to keep us thinking about the class, and the issues associated with the environment.  I learnt a lot about environmental issues that I was not familiar with before.  I also found the waste audit assignment to be very successful for myself.  It was a great way to look at my waste production, and the environmental action allowed me the opportunity to improve my waste habits.  Overall, I got a lot out of this class, and am grateful that I got the chance to take a class centered around current issues that our society faces.

Ted Talk: Wish to Protect Our Oceans / Sylvia Earle - Activities Blog #4

Summary
     This talk by Sylvia Earle is centered around the importance and preservation of the ocean.  Earle discusses her history and experiences with oceans, and through the use of her personal views Earle is able to highlight the importance of the ocean as the main life support system on Earth.  Earle delivers a strong introduction, with alarming facts about the degradation of the oceans ecosystems.  She states that everyone is connected to the ocean, and it shapes the earth, climate, and is the key to the human life cycle.  Earle makes it clear that humans are responsible for the loss of ocean assets, and that the impact is severe.  Another aspect Earle touches on is the benefit of technology, and how new technologies are needed in order to protect the oceans biodiversity, and to increase its resilience.  Through the use of humour and photos, Earle captures the attention of the audience.  She emphasizes the degree of degradation world wide, but remains optimistic by stating that there is still time to change the situation.  She also promotes that hope is derived from the already protected areas of the oceans.  To finish off, Earle states that "the time is now", and that in order to protect future generations, changes must occur immediately.

Impressions
     I found this video to be highly intriguing.  I thoroughly enjoyed listening to Sylvia Earle speak, and found her opinions to be honest and humble.  The series of photos are phenomenal and truly add depth to the video.  Seeing all the different species is fascinating, but it is amazing that this is only a tiny fraction of the life in the ocean.  It is interesting to think of the ocean as our life support system, but it is true we are all connected by the ocean.  The video also presented some shocking statistics, which really put into perspective how much damage the ocean has endured.  I agree with Earle when she says that the time to change is now.  If we start to eliminate the issues we are creating, then there is opportunity for restoration.  It is important for people to be aware of the impacts they are creating, and I believe that this video does a great job of highlighting the implications of our world, and what needs to be done in order to repair the damage done. 

Reading Summaries Blog #4

Life and Death of the Salt Marsh - Section #8
     This section was a small portion from a book written by John and Mildred Teal.  The introduction begins as a tale of the salt marshes, and is highly descriptive.  They describe the differences between a healthy marsh, and a sick marsh, including details such as the odors.  There is also a comparison between north and south marshes, and the functionality of people walking on them.  Another feature the authors describe is what the marshes look like during high and low tides.  John and Mildred go on to emphasize the implications of human exposure to the wetland and marsh ecosystems.  They state that humans directly and indirectly harm the wetlands, through ignorant destruction, and through pollution.  They also propose that the increase in coastal populations will degrade the wetlands even further.  Solutions to maintain the wetlands are offered by the authors, and they state that the wetlands must be preserved almost in entirety if the preservation of the wetlands is to have any real meaning.  In reality, the wetlands are more valuable as wetlands than what has become of them.

Ecosystems and Human Well-being - Section #10
     This reading follows the Millennium Ecosystem Assessment from 2005.  It discusses the fact that in the past 50 years humans have altered ecosystems more than ever before.  The assessment identifies three main issues associated with change and the management of the worlds ecosystems.  These issues are as follows: 1) Approximately 60% of the ecosystems examined are being degraded or used unsustainably; 2) changes being made in ecosystems are increasing the possibility of nonlinear changes in ecosystems; and 3) the harmful effects of the degradation of ecosystem services are being borne disproportionately by the poor, are contributing to growing inequalities, and can lead to poverty and social conflicts.  The assessment shows that there are no simple solutions, however a variety of options to better the sustainable management of ecosystems are available.  Through the use of many examples, the assessment addresses the issues surrounding proper ecosystem management, and highlights the changes that are possible in order to improve management systems.

Living Downstream: An Ecologist looks at Cancer and the Environment - Section #28
     The following selection is a piece taken from a larger work titled Living Downstream: An Ecologist looks at Cancer and the Environment, by Sandra Steingraber.  In this small section, Steingraber talks about her family and the variety of cancer types that several of her family members were diagnosed with.  She presents that humans are susceptible to their environments, and that one of the greatest causes of cancer is environmental exposure.  Personal stories and connections bring Steingrabers words to life.  As well, the quality of detail and description draw the reader into her journey, allowing them to gain a true sense of her experiences.  Steingraber also discusses information on isolated cancer cases, but was unable to find information on a combination of contaminants or encounters.  She goes on to talk about cancer's environmental roots, stating that societies are focused on genes being a major cause of cancer, instead of environments.  The piece finishes off by looking at the principle of the least toxic alternative: an approach that presumes toxic substances will not be used while other options are available.  The reader is able to obtain a clear idea of Steingrabers experiences and views from this short section of the her book. 

Our Stolen Future - Section #29
     This article from the textbook focuses on how chemicals have become a part of the human's environment and are ultimately becoming a part of their bodies.  The authors state that people forget that their well-being is rooted in natural systems, since people live in man-made landscapes.  The article compares the concept of synthetic chemical testing on animals to the actual effects of these chemicals on humans.  The notion is presented that animal testing is inaccurate since test animals are not humans.  The authors prove this idea with evidence showing that hormone disruptor's that threaten animals pose the same threat on human populations.  The article demonstrates that animal studies provide an outlet for identifying and investigating what might occur in humans.  It also displays that animal studies can deliver early warnings about the serious implications of synthetic chemicals.  Overall, this article was well organized and factual, and offered an in-depth look into the issues that synthetic chemicals pose on societies today and in the future.

Environmental Justice for All - Section #31
     This section focuses on the global issue of environmental justice: inequitable environmental burdens.  Robert D. Bullard suggests that pollution problems generally target the less affluent and poverty stricken communities of the world.  He discusses a series of summits that were held in order to improve the standard of living for people in less wealthy communities.  Bullard also looks at specific environmental justice cases, such as Bean versus Southwestern Waste Management.  Through a series of examples Bullard is able to emphasize environmental justice issues and their impacts.  He presents the triumphs of environmental justice strategies, while displaying the struggles associated with its implementation.  Bullard finishes by stating that in order for environmental justice to be achieved, there must be equal protection for impoverished communities, and that all people deserve to be supported and protected from the filth of pollution.

Question #1: Consider your food system... What do you like about it?  What do you dislike?

     This section of the course has been super interesting for me.  For many years now I have eaten organic, and in the past year now have been trying to eat local foods as much as possible.  I did not think of  my food in the concept of a food system before this point, and it has been a great way to further my awareness of what I am eating. 
     There are so many things that I not only like, but love about my food and where it comes from.  I think that it has a real earthy taste, which makes me feel more connected to the land.  I enjoy that I am supporting local farmers and markets instead of supporting large corporations.  I also feel good about taking the environment into consideration when I purchase food that is local and organic.  For me it is fun to be connected to my food and create great tasting dishes from it.
     There are a few dislikes I have regarding my food system.  I often get discouraged by people who see eating organic and local as a fad, or a trend.  For me eating this food is something I am proud of and when people pose a stigma on the product it makes me angry.  Another dislike would be the cost.  I do find that it costs a little bit more then conventional food, but this is something that I am willing to deal with, since I believe the products are worth the price.  One thing that I had not considered prior to the class was the impacts of organic food brought in from other parts of the world.  This is a concern for me because I do not want to create a large impact; it is one of the many reasons that I eat organic food.  Now I will be more conscious about where my organic food is coming from, and try to stay as local as possible.
     Overall, I am really invested and happy to be a part of the food system that I am in.  Like anything, there is always room for improvement, and I am willing to make changes accordingly.  Organic and local products are a great way to indulge and create wonderful food options.

Other Comments

     I was amused by the "Meatrix" video we watched in class.  I felt as though this was a good way to highlight the issues in the farming industry by adding humour.  It was also great to learn about the "Cool Local Food Initiatives" that I can become involved in.  I am already familiar with Fresh Options Organic Delivery (F.O.O.D.)  and learning about some other organizations was awesome.  Another positive thing I took from class was the Fort Whyte Farms.  I was not aware that there were farms there, and it is cool to see it at such a local scale.  Finally, learning about the concept of country food was super interesting.  I enjoyed hearing about my classmates' personal experiences.  The concept of country food seems to stretch so far, and connect with a lot of people. 

Ted Talk: How Food Shapes Our Cities / Carolyn Steel - Activities Blog #3

Summary
     This Ted Talk focuses on the evolution of food  in cities and how societies are currently facing a disadvantage.  It highlights the fact that people take their food for granted, not realizing the processes that make up their food systems.  Speaker Carolyn Steel uses humour and photos to capture the attention of the audience.  She emphasizes serious issues that have developed as a result of the current food systems.  Cities, urbanism, and the consumption of meat, are all identified as issues that already exist and will continue to increase if the Western diet sustains.  Steel compares the impacts of old world food systems with food systems today.  In the past, food was based on a local level, and did not have to travel far to make it to market.  People would visit markets daily to get food, but also to interact and socialize with others in the community.  Another aspect of the market was the real connection to the food; for example, animals would be bought alive and then prepared at home.  Today people have a limited connection to their food.  It is often bought frozen at the grocery store, and then heated up in the microwave.  Steel exposes that the Western diet in unsustainable, and will not be practical for much longer.  Her solution for the damaged food systems of today is to rethink the way food shapes society, and this can allow food to shape the world.

My Impressions
     I really enjoyed watching this video.  I think that Carolyn Steel did a great job of presenting the issues of current food systems and providing realistic solutions.  I liked her use of humour throughout the talk, and I feel as though it adds a sense of connection to the speaker.  I found it interesting to learn more about the details of old world food systems.  I was already aware of the use and purpose of markets in the past, but Steel was able to reveal fascinating facts about street names and locations based on the type of markets present in the area.  The views proposed by Steel were very true, and I agree that people need to have a connection with their food and where it comes from.  I think that it is important to be involved in our food systems and to value what we have.  Overall, I thoroughly appreciated the messages and wisdom of this video.

Reading Summaries Blog #3

Human Domination of Earth's Ecosystems - Section #9
     This section focuses on the impacts that humans generate on ecosystems, including land, oceans, and biogeochemical cycles.  It centers around the idea of human functions causing change on the earth, resulting in a loss of biodiversity.  This piece argues that the most substantial human change to the earth is land transformation, which ultimately influences all other aspects of the land system.  Land transformation is linked to local and regional levels of climate change.  The authors suggest that land transformation needs to be looked at on a broad scale in order to promote positive land transformation practices.  Ocean systems are also touched on, pointing out the large scale and destructive practices of the fishing industry.  Fisheries often fish predator species, or over fish the resources, which both lead to imbalances in marine ecosystems.  This reading emphasizes that humans are responsible for the impacts on earth's ecosystems, and in a sense humans are holding the planet's future in their hands.  Finally, the reading points out that the negative results from human activities are issues that society needs to confront now and efficiently.

Could Food Shortages Bring Down Civilization? - Section #25
     This article from the textbook discusses the risks of food shortages on a variety of levels, while looking at the impacts of environmental decline and the lack of intention to restore the environment.  Author Lester  Brown highlights the case of failing states (nations), determining that states fail when the national government cannot provide fundamental security.  Brown emphasizes that when a state fails it becomes increasingly dangerous since they threaten political stability on both a local and global scale.  When a state fails there is often an increase in terrorism, drug use and trafficking, weapon distribution, and refugees.  The case of a failed state is tied to the issue of food shortages.  When a state or nation cannot produce or import enough food for its people then it begins to loose stability.  Also related is the inflation of food prices,  if a food product increases in price less wealthy states cannot afford to buy, and therefore leads to the case of a failed state.  Another issue that Brown focuses on is the consumption of freshwater for irrigation purposes.  He points out that water is being depleted and cannot be replenished quick enough to sustain food systems in today's world.  Through a series of shocking examples Brown is able to emphasize the negative impacts of modern food production and how these practices are not sustainable.  Ultimately, Brown provides a variety of solutions that can help reduce the impacts of shortages for the future. 

Women's Indigenous Knowledge and Biodiversity Conservation - Section #37
     This reading is a small portion taken from a larger compilation by author Vandana Shiva.  Shiva identifies the connection between women and diversity, emphasizing that both enable each other.  A part of this reading focuses on the evolution of monocultures and uniform production, which Shiva argues hinder biodiversity.  She makes it clear that nature's diversity is not accepted, and therefore it is exploited and degraded.  Shiva uses examples to compliment her arguments, without creating a bias opinion.  A strong example that she uses is the displacement of indigenous people in third world nations through the practices of progressiveness and technology.  A Westernized view is being pushed on these groups and they are not being given the option to accept it or decline it.  Instead they are stripped of their rights and forced to adapt to a foreign lifestyle.  Shiva highlights that it is the women in indigenous tribes that maintain the biodiversity of the natural world, contributing to dairy, forestry, and plant and food production.  Since women's values are being disregarded the biodiversity is disregarded as well.  Shiva suggests that to preserve biodiversity women must be valued, and for women to be valued biodiversity must be preserved.

Blog Reflections Blog #2

Question #1: Can parks meet its dual mandate of access and protection?

     I do not believe that the dual mandate is a possibility.  I feel as though by allowing access to parks, where wildlife and natural landscapes exist, degradation will occur.  Although some people are respectful of parks and the wildlife that is present, there is a large portion of people who abuse these natural places.  To me the protection of parks is far more important than the access.  Unfortunately, I am not sure that this is an option since there is such high demand from people to experience natural places and see wildlife in its natural environment. 

Question #2: How can this be achieved in Wapusk?

     If protection of the natural environment in Wapusk is to continue then access should not be allowed.  Currently, limited access is granted on certain conditions, but to some extent this still poses a strain on the natural environment.  In order to preserve Wapusk, limited access must be sustained.  An even better solution would be no access to any point of the park.

Question #3: What future would you like to see for the Alberta Tar Sands?

     My opinion for the future of the tar sands is to stop development entirely.  The Tar Sands are a toxic project that degrade the natural environment, and waste valuable resources such as water.  I see no point in putting more resources into a project that does not offer an equal or better return.  To me the negative factors far exceed the positive ones.  I feel as though the money could be spent on the development of sustainable energy sources that we will have to depend on in our near future.  Another factor that fuels my opinion is the increased health risks of the people who reside near the tar sands and the tailings ponds.  It is not a healthy environment to be living near or working in.  I believe that the Canadian government needs to take responsibility and set an example by stopping production of the tar sands.  If a change like this can occur I believe it will attract better opportunities for Canada than the fight over our dirty oil. 

Other Comments

     On a lighter note, I really enjoyed watching the film Fresh in class this week.  I think that it gives a really honest look into the farming industry and emphasizes the negative impacts of conventional farming.  I myself already eat organic and local foods, but found it interesting to think of other peoples reactions in the class.  While watching this film I found a feeling of anger inside me due to the treatment of the animals and the ignorance of people in the industry.  I feel as though this film, and the book I read for the position paper, The Value of Nothing, complimented each other well and followed many of the same concepts.  Overall, I hope that this film can continue to make an impact on others as it has on me. 

Reliance on Fossil Fuels - Activities Blog #2

     After thinking about the extent to which I rely on the fossil fuels I decided that I am comfortable with my reliance on them at this point.  This question got me to thinking about my future and how much I might rely on fossil fuels then.  Although I am currently okay with my reliance, I am positive that I want to reduce my use of fossil fuels in the near future.  I am not entirely certain that my reliance on fossil fuels will be sustainable for the next 10 years, and this prompts me to make changes.  Up to this point in my life I have been conscious and aware of the impacts of fossil fuel use, but recently I have learned to look at my impacts of using fossil fuels.  When I first started to think of the changes I would have to make in order to reduce my fossil fuel consumption it was overwhelming.  After considering it over a period of time I have come to the conclusion that I do not have to change my life drastically to make improvements.  By making small changes one at a time I can eventually achieve a more sustainable reliance on fossil fuels, and hopefully become independent of fossil fuel use in my future. 

Ted Talk: Transition to a World Without Oil / Rob Hopkins - Activities Blog #2

Summary
     This was  a video surrounding the issues of peak oil and a transition away from an oil driven world.  Rob Hopkins discusses how society has discovered a non renewable resource, oil, and has based an entire way of life around it.  He presents how society's well being is directly related to oil, and how there will not be this luxury in the near future.  Hopkins offers the solution of taking a "realistic approach" in order to move forward and face the current situation.  He makes it clear that change cannot be based on technology alone.  In order to improve the above issues the concept of "Transition Response" is proposed.  Hopkins describes this concept as looking at the issues that society faces, and responding with integrity and adaptability.  He touches on the idea of resilience versus sustainability, saying that resilience focuses on reorganizing the function of basic processes, and in turn this reorganization will create a more resilient society.  Hopkins closes his discussion by saying that society does not have to change everything right now, but society needs to work with the current changes.  Overall, this video was able to highlight the current issues surrounding peak oil, and offers realistic solutions for the societies that are ready to implement change.

My Impressions
     I feel as though this video does a great job of emphasizing the current issues of oil use without forcing it in my face.  To me Rob Hopkins is a great speaker, and he is able to draw his audience in with the use of humour and intelligence.  I like the comparison between resilience and sustainability, and feel as though the concept of resilience described by Hopkins is achievable.  I found the data presented to be quite informative.  I was interested to learn that there are 98 oil producing nations, and that 65 out of the 98 have already reached peak oil.  Another great part of the video was the insight into Hopkins Transition Response organization.  Hearing about the differences that people are creating all around the world gives me a sense of hope, and also compels me to become involved.  I enjoyed this video and the positive changes that is is promoting.

Reading Summaries Blog #2

A Sand County Almanac - Section #4
     This selection is taken from Aldo Leopold's writings based on nature.  This piece focuses on the evolution of ethics from the past to the present during his lifetime.  Leopold describes ethics in two themes, an ecological standing and a philosophical standing.  He states that ecologically, ethics are a limitation on freedom, and philosophically, ethics are the difference between social and anti-social.  Through these theories Leopold discusses how ethics currently try to relate the individual to society instead of nature.  This in turn shows that land has no ethical standing which leads to the lack of obligation in preserving or respecting the land.  Leopold strives to improve land ethics by highlighting that land is an extension of communities.  Therefore, people should respect the land as they would their communities.  Leopold states that education is the key to the improvement of land ethics and that in order to make progress the notion that economics controls all land-use must be abolished.

The Historical Roots of Our Ecological Crisis - Section #6
     This reading by Lynn White Jr. discusses how changes in human ways often effect non-human nature.  The reading offers a variety of examples which emphasize how humans effect nature indirectly.  White looks at human change in a historical sense and identifies that through the evolution of technology and science humans have altered the natural environment.  He goes into detail about the lack of technological power before 1850 and describes the level of which humans have destroyed the planet in such a short period of time.  White says, due to the massive increase in population, which increases garbage, sewage, and urbanism, the degradation of the environment has been accelerated.  Another focus of the article touches on the influence of Christianity on man's relationship with nature.  White states that current technology and science stems from a Christian background, and creates an image of human superiority over nature.  The reading ends with White's views regarding solutions of environmental crisis, stating that society cannot expect a solution derived from current technological or scientific practices since they are so heavily rooted in Christian ideologies.  Instead White proposes that in order to improve the situation society needs to re-evaluate its current religious views if a change is ever to occur. 

A Path to Sustainable Energy by 2030 - Section #13
     This report by Mark Z. Jacobson and Mark A. Delucchi focuses on the need for sustainable energy in the very near future.  Jacobson and Delucchi propose a plan for the full use of sustainable energy by 2030, as evident in the title.  They suggest that this plan is possible, but it is more likely to see a full shift within the next 50 years.  In order for this plan to become a reality Jacobson and Delucchi state that through the combination of wind, water, and solar energy this plan can be achieved.  They are aware that the changes will be drastic, but fully believe in this technology.  Jacobson and Delucchi state that the world energy system change will rely on three factors: 1- technologies chosen; 2- availability of critical materials; and 3- economic and political cooperation.  These factors can have barriers associated with them, such as the ability to obtain critical materials for installation.  Although there are some hurdles, Jacobson and Delucchi remain confident that this plan can be put into motion.  A key role in keeping the wind, water, and solar energies running is the utilization of recycling within the energy system.  If materials can be recycled this will lead to a greater success and minimize waste even further.  Jacobson and Delucchi provide solutions to implement this plan as quickly as possible.  They state that all nations will need to be willing to cooperate and invest in the energy system if it is to be carried out efficiently.  Overall, Jacobson and Delucchi strive for the transition from an "old, dirty, inefficient system, to a new, clean, efficient energy system". 

Summary for Policymakers: Climate Change 2007: The Physical Science Basis - Section #23
     This selection is an analytical study centered on climate change over time.  The study suggests that recent climate changes are due to anthropogenic activities and increases in greenhouse gas emissions.  Data determined from ice cores shows the massive increases in atmospheric gases in the recent past.  This data helps to reinforce the theories of anthropogenic climate changes.  Through a series of examples the study highlights the impacts of climate change on a global scale, and what issues will develop in the future.  The data and examples are given in figures and tables, which allow the reader to visualize the content.  The main climate change issues focused on in the study are heating and cooling.  The study states that heating is due to carbon dioxide, methane, and nitrous oxide, and cooling is due to aerosols, such as sulphates, black carbon, and dust particles.  A projection from the study states that heating in the future is expected to be greatest over land.  The study finishes with a list of future implications of climate change, and makes it clear that even with the reduction or stabilization of greenhouse gas emissions climate change will persist for centuries.

Blog Reflections

Question #1: Is there a danger to a growing disconnect from nature?

     Yes, I do believe that there is a sense of danger in people becoming less connected with nature.  I think that it is becoming more difficult for people to appreciate the earth, and realize that we need it in order to survive.  I believe that society does not think about the repercussions of our impacts on nature, or value the most basic necessities such as food and water that come from the natural environment. 
     I also think that it is scary to see a transition of children inside playing video games versus playing outdoors with friends.  I was very shocked to hear in our class discussion that children of this age are not expected to live longer than their parents.  I think this shows that technology is not always positive, and that it can damage the health of a society.
     Overall, I believe that an effort needs to be made to keep in touch with nature and the natural environment that surrounds us every day.  If people can connect with any part of nature I believe it is a step in the right direction.

Question #2: Where do your environmental ethics lie?

    I believe that I fit into the biocentric level.  I try to understand and appreciate all living things.  That being said, I am also aware that I do not appreciate everything all the time, but my intentions in preserving the natural world are real.  I try not to focus on the monetary value of things, which I believe separates me from the anthropocentric level.  Overall, I enjoy being surrounded by nature and being engaged in the natural world around me.

Other Comments

     I really enjoyed the video that we watched in class on Monday.  I found it to be very truthful, and I took a lot out of it.  There was a quote from it that I thought was fascinating and very real: "we are insulated from the natural world".  I agree with this statement completely, and I can see how I am insulated everyday through technology, and media.  My goal is to try and focus on connecting with my natural environment as much as possible, and try and let go of my "insulation".
    

Reading Summaries

Tragedy of the Commons - Section #7
     This reading was taken from an essay written by Garrett Hardin.  It centers around the idea of a common ground or land that had been stripped of its worth due to people consuming as much as possible, and not thinking of the harm it has on the common land, thus resulting in a tragedy.  The essay discusses how the current world situation surrounding depleted resources cannot be solved through technological practices.  It must be looked at in a natural manner if resources are expected to one day become replenished.  Hardin applies the theory of the Tragedy of the Commons to a variety of situations, including a shared grazing land.  He suggests that it is not only stripping the land of its resources that creates damage, but also the addition of pollution.  Another strong topic that Hardin focuses on is the idea of consciousness.  He touches on the strengths and weaknesses of the consciousness, and how it plays a large role in the future.  The essay ends with some suggestions on solutions for the future, and a way to end the Tragedy of the Commons.

Human Carrying Capacity - Section #35
     This section was a small portion from a book titled How Many People Can the Earth Support? written by Joel E. Cohen.  Based on the title of the section, this portion of the book takes a look at the Earth's human carrying capacity.  It follows a case study of Easter Island, describing the first people to inhabit the island, and the changes that it underwent.  It gives examples of specific trees that were used to make rope, but that no longer exist on the island.  It goes on to highlight some of the causes that damaged the island, and mentions that the island is currently occupied by Chileans.  The reading also touches on Earth's population growth and decline.  Cohen states that if the Earth actually held the limit of people it could support, then humans would simply not tolerate it.  Cohen also describes carrying capacity as a transition through time, using an example of a man in four positions.  He believes that carrying capacity cannot be looked at as a constant due to continual changes around the world.  Therefore, in order to gage carrying capacity we must base it on future assumptions instead of the current world.

Collapse:  How Societies Choose to Fail or Succeed - Section #38
     This article from the textbook covers a series of issues that lead to the success or failure of a variety of societies from around the world.  The author, Jared Diamond, gives thorough examples of societies that either thrived or diminished.  Through a list of eight problems Diamond highlights what caused societies to fail in the past, while putting emphasis on the same issues that continue to effect societies today.  Along with the eight original problems Diamond touches on four new problems that societies currently face, including human caused climate change, and energy shortages.  Diamond was able to pose interesting questions regarding technology as a help or a hindrance in the future.  He emphasizes that it is not just one factor that causes a society to fail or succeed, but a combination of many factors.  Diamond also suggests that in order to solve societies issues, large corporations need to work with the environment for a change to occur.

Ted Talk:A Fragile Earth/ Yann Arthus Bertrand - Activities

Summary
     This was a short video surrounding the impacts that humans have on the earth.  It highlighted the fact that people are in denial towards their effects on the earth, and that "people do not want to believe what they know"(1).  Through a series of images Bertrand expresses the seriousness of the issues that our planet faces due to human ignorance and greed.  Bertrand also touches on the release of his film titled Home, which is based on similar topics.  The  video shows Bertrand's efforts in reaching people by showing several videos from the 5000 interviews that he conducted around the world.  Overall, the video gave a great introduction into the impacts of human life on the planet, and offered a positive message to those who are willing to listen and learn.

My Impressions
     I felt as though this video was extremely eye opening.  My impression of Bertrand is that he is a strong person who is able to share his message in an honest and open manner.  The series of images in the video were stunning and shocking to look at, which made the message more powerful to me.  I found that the statistics presented were distinct and showed the severity of the damage that we are inflicting on our planet.  I was amazed to hear that 100% of the coral reef has the potential of being wiped out by or before the year 2050.  I also found the interviews to be inspirational.  It was incredible to hear from the man who said he had accomplished more in a wheelchair than he had with his legs, and it gives me the feeling that I can do more in my life.  I enjoyed watching this video and learning about the impacts we create and the threats that the impacts cause. 

A Walk in the Park - Activities

     I decided to choose the nature option for part of my blog. I feel as though it was a wonderful opportunity to focus on school while being in nature, and instead of reading a book, or being in front of a computer screen. Connecting with nature is already something that I enjoy, but like most people, probably don't spend enough time actually doing it. That being said, I thoroughly appreciated my walk along the banks of the Red River.
     I found that there is so much natural beauty in the simplest of things.  For instance, the slight change in the colour of the leaves, and the sound that they make when you walk over them.  It was nice to spend time in the changing of the seasons, and see a variety of colours like green, brown, yellow, and even light pink leaves.  A specific image that stood out to me was the giant trees that had collapsed, but continue to function in their surroundings as support for other trees, and animals.  It allowed me to see that it is all an interconnected system that goes through cycles and change, but does not need perfection to thrive. 
     While I was walking and observing I was overwhelmed with a variety of feeling.  It was so peaceful, calming, relaxing, and safe.  All of my feelings out in nature were positive.  I could really gain a sense of enlightenment while I was in a natural environment versus one busy with traffic, and people.  It was great to hear the sounds of birds, and the rushes of wind through the trees.  I felt as though the air was fresh and that I could breathe deeply.  The whole experience was genuinely refreshing, and gives me the urge to go out and enjoy this nature more often.
     One question popped into my mind as I was leaving the park.  I wondered if people take for granted the ability to go out and interact with nature.  After pondering this thought I came to the conclusion that most people probably do, including myself.  Nature is not something that anyone can control; therefore we take it for granted that it will sustain, and that we can depend on it.  I believe now that we should look at nature as a privilege, and respect our natural environment as much as we respect the homes we live in.  I truly gained a new respect for the nature that surrounds me, and will try to enjoy nature on a daily basis instead of taking it for granted.
