Anti-development Upstate stakeholders on NYC Water Supply

This article supports the group of anti-development Upstate stakeholders by discussing the effects of the natural gas drilling occurring in Pennsylvania on the countryside. The Marcellus shale is a rock formation of 95,000 square-miles that extends from West Virginia to New York. This formation contains large amounts of natural gas which can be obtained by a hydraulic fracturing process. Since the affected areas in Pennsylvania are located on the same rock formation as Upstate New York, similar conclusions can be drawn from the effects of the hydraulic fracturing in Pennsylvania. The natural gas drilling has caused a decrease in property values and in the beauty of the surrounding natural environment.

The Hallowich family, who own 10 acres of farmland in a drilling area of Pennsylvania have witnessed the degradation of their surrounding environment and a decrease in their property value due to the fracking in their area. The onset of drilling near their home brought “a gas processing plant, a compressor station, buried pipelines, a three-acre plastic-lined holding pond, and a gravel road with heavy truck traffic,” clearly ruining the natural surrounding landscape they once enjoyed. Along with the eyesore of industrial equipment, loud noises from the traffic and operations interrupted the Hallowich’s lives. Also, since many residents extract their drinking water from shallow pumps, there is a danger of water contamination from the fracking fluids. While these fluids are usually contained, “at least 130 cases documented since 2008 by the DEP, drilling waste-water has spilled into creeks and tributaries due to holding pond overflows, pump failures, and other errors,” proving that there is a chance for dangerous fluids to enter nearby waterways and contaminate resident drinking water pumps. The Hallowich family also complained about a bad smell and dangerous gasses coming to their house through the air and causing burning throats and eyes. All of these disturbances have lowered the property value of their land, with a real estate agent pricing it at $200,000, though the Hallowichs are looking to sell for $500,000.

The problems faces by residents in Pennsylvania on the same Marcellus shale formation can be viewed as a cautionary tale to what could happen to residents of Upstate New York. For these reasons natural gas hydraulic fracking should not be developed in Upstate New York. The industrial compounds will ruin the beauty of the surrounding nature by taking up a lot of space and introducing new roads with high traffic. The danger of the fluids polluting the air and waterways is also an issue which would contribute to the decrease in property value and would have a very adverse effect on property owners in the area.

Marris Chapter 10

Emma Marris concludes Rambunctious Garden by weighing in on some of the goals that could be strived for. Throughout the book, Marris talked about how nature is not only a “pristine” ideal and it cannot be put back into its original form, or to a certain baseline. Thus there are other goals to focus on when thinking about nature, yet she points out that all these goals cannot be accomplished together, so it is up to people to decide what goal would work best for each area.

I don’t quite agree with the first goal Marris presents, which includes protecting the rights of other species. While it makes sense to try and protect the rights of animals on a certain level, deep ecologists believe that “all living things have intrinsic value and deserve to be protected for their own sake” (154). Many deep ecologists put the rights of the earth on the same level as human rights and claim that humans have a moral obligation to reduce their population and tap into nature less. I don’t believe it is correct to place humans on the same level as non-sentient parts of nature or even other animals and it seems more morally correct that humans should place their own interests above any other aspects of nature.

The second goal Marris mentions is to protect charismatic megafauna. This may be a good idea because people will tend to support and donate to conservation and protection funds if they like the animals that the fund says they are trying to protect. If the fund just mentioned plants that could go extinct or a species of insect, very small amounts of people would actually care about such matters since others might view them as miniscule. On the other hand, discussing the dangers posed to popular species would get more people interested in conserving ecosystems.

Marris talks about several other potential goals, including the idea that nature should be protected just for the aesthetic experience of nature. I agree with this goal because nature is something that many just enjoy watching and spending time in nature. I also agree with Marris’s statements about the beauty found in both artificially and natural created landscapes. Examples such as Niagara Falls and the Sandhill cranes display how the combination of human and natural activity creates an amazing display. Marris sums up the collaboration very well with the line, “This conscious and responsible and joyful cohabitation is the future of our planet, our vibrant, thriving, and rambunctious garden” (170). As Marris sums up her book, I find that I agree with a few of her ideas, such as how nature has been altered and it is very dynamic. I agree that nature should not be forcibly kept static to resemble an arbitrary baseline and there should be different goals that apply to the variety of nature in the world, whether its the small garden in a city or a rural area.

Marris, Chapters 8 + 9

In chapters 8 and 9 of Marris’ Rambunctious Garden, Marris once again points out how ecologists shouldn’t just be concerned with restoring and taking care of a “pristine” nature, but they should embrace change and develop he nature in urban areas as well. Marris begins chapter 8 with a discussion on how ecologists have tried to restore streams. Margaret Palmer, a stream restoration expert, says “new picture of pre-European streams will just replace one arbitrary baseline with another-neither of which takes into account the changing nature of the landscape” (124). This supports Marris’ point of the arbitrary goal of many ecologists, to continue to conserve nature by restoring it to a certain baseline.

The streams are actually designed rather than restored since “no restoration reproduces exactly the ecosystem of hundreds of years ago” (125). It is the goal of restoring an ecosystem to it’s “proper” baseline that many ecologists chase. They want to restore an ecosystem to a historic baseline that is “morally better” as well as “maximally efficient” at certain ecological functions (126). In doing so they are creating new, designer ecosystems, “even if they are inspired by the past” (126). But just because an ecosystem looks as it used to, Marris points out, doesn’t mean it will behave in the same manner. She also points out that often the historic ecosystem isn’t always performing better at certain functions that novel ecosystems and often a well constructed designer ecosystem will be better than a “recreation of a historical ecosystem” (127).

Because the ecology and nature of an area is constantly changing and adapting, there is no point in establishing a baseline and striving to obtain it since the baseline is not an ideal scenario since nature is always dynamic. Often it is even impossible to restore the original ecosystem, such as in the eucalyptus woodlands in Australia, where the soil became to salty for the historical plants to live. Instead, other species that thrive with salt could grow there. Richard Hobbs states, “You are not going to get the previous ecosystem back, but you can still aim for something that is valuable” (129).

I agree with Marris’ statement that ecologists should try to stop using the word “restore” and instead just design high functioning and useful ecosystems, as well as leave some land unmanaged, “just to see what it does” (131). Marris sums up her main points in the end of chapter 9, discussing the importance to preserve and enhance nature that is all around us. She brings up an interesting point of how nature shows portray nature as pristine and untouched, yet this is very rarely the case, and they convince viewers that the “pristine” idea of nature is the only true nature that there is. Marris points out many examples of how nature is all around us and I agree with her view of nature, which includes all of the animals and ecosystems that are directly around humans. Just because nature isn’t untouched, doesn’t mean that it shouldn’t be regarded as nature.

Marris, Chapters 6 + 7

Ecologists are very often opposed to a new species entering an environment. They believe that the new species will only destroy the original ecosystem and become an invasive species. A common story that many ecologists tell about the effects of an invasive species, Marris relates, is how “a species invades, and the ecosystem collapses, species go extinct, and complexity and diversity are replaced with a monotonous and weedy landscape dominated by invaders” (97). Marris argues that this is not always the case and discusses the idea of a “novel ecosystem,” one that represents “the future of our planet” (122). I agree with Marris that these ecosystems should be studied since they are dominant in the world and they are not as harmful as many ecologists believe them to be.

Though many ecologists do not believe that exotic species would ever be able to help increase diversity, often exotic species can actually end up helping the ecosystem and allowing the other species to continue to survive. Marris points out once again that humans have introducing new species to areas for many centuries. While sometimes the new species can bring about a lot of harm like diseases they can carry with them or if they become predators and eat an entire population of native species, “extinctions that are directly attributable to introduced species are quite rare” (104). Though such damage is very rare, “these emerging, exotic-dominated ecosystems still look like trash to most ecologists,” Marris writes, “but a brave few have embraced them and given them a more positive name: novel ecosystems” (109).

Marris defines a novel ecosystem as ones where there was “anthropogenic change” at one point but are currently not under management by humans (114). This applies to most ecosystems in nature because they almost all have been affected by humans in some way. In a novel ecosystem, new species may be introduced into the area, something that ecologists fear due to the risk of the new species becoming invasive and “ruining” the ecosystem. In some cases, novel ecosystems can cause “homogenization and extinction” but they can also foster “increased diversity and brand new species” (122). For example, in Puerto Rico, the exotic -dominated ecosystem actually was “functioning better than nearby native forest” (113). Novel ecosystems are often very beneficial. They can can provide a habitat for the native species if their habitat is gone and they can sometimes even help restore the native species. Rather than a decrease in diversity, as ecologists assume will happen in a novel ecosystem, diversity may instead be on the rise. One hypothesis for the increased diversity is that the exotic or introduced species may initially run rampant but will eventually calm down due a built up resistance by the surrounding species. Thus the new species may become integrated into the ecosystem and form the potentially diverse novel ecosystem. Ecologists need to stop trying to keep nature in a static position and embrace studying the many new forms of nature that evolves.

 

High Line and Stalter

A wasp

The High Line on the West side in Manhattan has an abundance of nature, as evidenced by my visit there and Stalter’s report on the ecology there. Even though it was starting to rain and very windy, I could still find several different pollinators around the plants on the High Line. Because of the wide array of nature interacting with humans in the middle of the city, the High Line displays Marris’ concept of a Rambunctious Garden.

A bee

I had gone to the High Line several years prior but I had never noticed the variety and extensiveness of the plant fauna there since I was only interested in the interesting architecture surrounding it. Walking through the High Line I noticed a very large range of plants and flowers which I did not expect to see in the city. I was surprised by the dense areas of plants which were thriving on the High Line. Many pollinators seemed to like one certain type of plant and I found a variety of different bees or flies mainly around them. I think I saw a couple of different bees and perhaps a wasp, as well as flies and some other unknown insects. I also spotted several birds and a few butterflies but I was unable to capture a picture of them since they flew away rather quickly. Along with the nature there is also a lot of human traffic. There are many tourists there and the variety of people visiting the High Line is also very diverse.

Stalter confirms in his article and report that there is a very large variety of plant life and species at the High Line. He discovered a total of 161 species there, with 82 native and 79 introduced. Stalter goes on to describe how the “species richness at the High Line is greater than species richness at four nearby New York City sites.” Stalter also concludes that one factor for the high diversity of species at the High Line is human disturbances. This supports Marris’ idea of the rambunctious garden. Marris talks about how all nature is affected by humans and how well nature can adapt to human interference. The High Line is a great example of this. Disturbances by humans brought a lot of the plant life to the High Line, which in turn may have attracted the many pollinators that are there currently. The High Line is not a “pristine” or untouched portion of nature. On the contrary, the High Line was originally an abandoned railroad track and over time it grew into the urban ecological system it now is. Nature is clearly thriving in the area while still interacting and adapting to the constant human traffic that visits the High Line each day. The High Line is truly a rambunctious garden in the city.

Assisted Migration

Emma Marris discusses the topic of assisted migration in Chapter 5 of her book, “Rambunctious Garden.” Because of problems with climate change, many species will have difficulty adapting to the changing environments around them. This may cause extinction of the species since many animals are unable to migrate or relocate to a new ecosystem. There may be “barriers in the way” preventing them from moving, including seas and cities to block an animal’s migration path and even a road could be a hindrance to small animals (75). Some species might also not be capable of moving large distances in order to move to an environment better suited for them. Assisted migration may be a solution to such problems, and it involves humans transporting a species into a new area for them to continue to survive. As Sally Aitken, professor of forestry genetics says, “Assisted migration is going to be necessary to save some species” (94). Whether or not ecologists are willing to undertake assisted migration is another question. It is impossible to transport every single species in an area and there are several other problems associated with assisted migration. The species being moved might not be able to adapt to the other environment, perhaps because of an unobserved element such as “specific soil microbes or microclimatic condition” (77). The results are unpredictable and an assisted migration might not save the species. The relocated species could also potentially harm the new ecosystem by becoming an invasive species and pushing out the native ones (77). Another problem encountered by assisted migration is the high cost of transporting the species.

While there may be some problems and difficulties with assisted migration, it can also be a useful tool for urban ecosystems. As Marris points out, “Surely assisted migration of these ecosystems would just be a continuation of the care our species has put into them for thousands of years” (87). Since humans have already been interfering with ecosystems, assisting the migration of several species in order to save them sounds reasonable, especially in urban ecosystems, where the number of species is declining.
“Most of those that did report data over time showed declines in species richness [in the Metropolitan New York area],” explained Linda Puth and Catherine Burns in their paper, “New York’s Nature: a review of the status and trends in species richness across the metropolitan region.” There is a large downtrend in the variety of species of many animals, most often in a native species (Puth, Burns 21). Assisted migration could help restore the species richness in an area by bringing a species to a certain area where it will prosper. Thus assisted migration may be a helpful tool in saving species by improving their living conditions, yet there are also several risks involved that should also be taken into consideration.

 

Marris: Rewilding

Rewilding, as discussed in Emma Marris’ book “Rambunctious Garden,” is an interesting concept. While it does not preserve the “pristine” idea of nature, it can create unique experimental reserves. Though rewilding is entirely “man-made” (70), it can be a way to study how an ecosystem adapts to human interference, as all of nature is already affected by humans. As Marris mentions, there are already large African mammals roaming free in Texan ranches, yet ecologists tend to “ignore any area that doesn’t look pristine” so “no one is studying the fascinating question of how these ‘Texotics’ interact wither their new environments” (64).

The Oostvaardersplassen in the Netherlands is a good example of a positive rewilding. Though the area is designed “to run as it did 10,000 years ago” (57), many animals are already extinct so it is essentially a “brand-new ecosystem” (58) which was designed when similar animals are introduced. The Oostvaardersplassen has a large variety of species, including red foxes and Heck cattle, and “life and death are plainly on display” (70). I agree with Marris, who writes, “the experimental reserve … is worth having” even though it might not be a correct depiction of the past because the interaction of nature is worth studying regardless if humans created it.

A large critique of rewilding is the concern that ecologists are “playing god.” In reply to such claims, Josh Donlan, a field ecologist says, “Well I don’t buy that. We are already playing god,” explaining how we already live in an “intensely managed world” (64). Rewilding should be viewed as a “cultivated, man-made, created” nature (70) and appreciated for that fact. It seems that some ecologists view rewilding the wrong way, creating a “seeming paradox” (71). Frans Vera, the ecologist behind the Oostvaardersplassen claimed to be creating a “natural ecosystem” which he considered to be a lot better than a “cultivated one,” yet the entire area is affected by humans: the animals were brought in, civilization is seen all around the area, and it is below sea level (70).

While rewilding can create interesting ecosystems of nature, it may also be very harmful to the original ecosystems as well as to humans inhabiting the surrounding area. The species which are introduced into the area could end up acting as an invasive species and wiping out many populations. As ecologist Dustin Rubenstein mentions, the results would be “unpredictable” (65). There is also the danger of introducing predators into a new environment. Predators could not only wipe out many native animal populations but they could also harm many humans as well.

Thus I believe rewilding to potentially be positive, if ecologists focus on how the new ecosystems are man-made yet still nature rather than attempting to preserve a prehistoric baseline. There can be a lot to study from ecological formations created through rewilding, it just seems there needs to be a different approach to how rewilding is viewed.

 

Rambunctious Garden – Chapters 1 + 2

The main point Emma Marris, author of Rambunctious Garden: Saving Nature in a Post-Wild World, is trying to get across in her book is represented in one of the lines from the opening chapter: “This book is about new ways of seeing nature.” Marris tries to point out the flawed way many ecologists and conservationalists see nature and try to preserve it, and how due to the changing definition of nature, there must be new ways to study and take care of it. Marris has made a very good case in the first two chapters of her book, explaining the dynamics or nature and bringing many examples of her experiences studying the ecology of many places, including Hawaii, Australia, and Yellowstone Park.

Marris argues that nature must be viewed and understood correctly in order run it correctly. Her main argument is that people must admit that we are running the world in order to run it “consciously and effectively.” Marris provides many examples of how people are running nature because of the ways nature is lost to us and how people have brought about so many changes in nature. She explains that nature is lost in two ways, it is destroyed and we “have hidden nature from ourselves.” People often believe nature is “out there” somewhere but not accessible or near to us. Marris makes a good case talking about the everyday aspects of nature and how it is “almost everywhere.” She mentions nature is in the commonly thought of places such as in the forests but it is also found as well in the cities, where plants still grow and bees still pollinate. Focus on preserving nature is placed onto natural parks but because nature can be found everywhere, Marris argues there should also be a larger focus on the everyday nature found around people, whether it be in a large city or rural area.

Conservationalists are “desperately trying to stop the wilderness from changing” yet as Marris points out, “there is no pristine wilderness on planet earth.” People have been changing the landscape for many years on a global scale with things such as “climate change, species movements, and large-scale transformations of land.” Marris provides many examples of the way nature is adapting such as how “bobcat families [are] moving into foreclosed suburban homes.” Because nature is constantly changing, “whether humans are involved or not,” there are many problems with the common practice by ecologists of setting a baseline when studying an area. A baseline is used to compare the current ecological state of an area to a certain period of time, but many factors affect the validity of such measurements.

Marris’ main point of the book seems to resonate in one of her quotes, “we can find beauty in nature, even if signs of humanity are present.” Marris disagrees with the the static way ecologists are trying to preserve what they consider as the only nature worth preserving, and argues that nature is all around us and effected by us, so it should be studied with that in mind.

 

Alice Cogan – Post for 8/30/12 – Anthropocene

Karieva uses the word anthropocene to describe the current state of the world, where humans “dominate every flux and cycle of the planet’s ecology and geochemistry.” The anthropocene era is one where humans have affected every aspect of the natural world and have thus become part of it. Karieva mentions that almost all of the world has already been shaped by humans and that humans will continue to alter it. Vitousek similarly emphasizes people’s impact upon the world, stating, “In a very real sense, the world is in our hands—and how we handle it will determine its composition and dynamics, and our fate.” Karieva and Vitousek both agree that people are the major forces which continue to shape the world.

Talking about the anthropocene era is a very useful concept for thinking about nature. Both Karieva and Vitousek explain the effects of humans on the world. Vitousek mentions how people have greatly altered land through agricultural processes or other enterprises, contributed to a loss of biological diversity, brought about climate change, and even affected the global biochemistry. Vitousek states, “all of these seemingly disparate phenomena trace to a single cause—the growing scale of the human enterprise.” Vitousek blames the problems in nature on human’s interactions with nature, mentioning the “global consequences of human enterprise” and claims we should work to “reduce the rate at which we alter the earth system.” Vitousek agrees with the idea of an anthropocene era, yet has somewhat different ideas from Karieva as to how the era of humans should be regarded.

Karieva mentions the issues with conservation, which instead of keeping nature pristine and untouched, actually exacerbates the human presence. Conservation tactics such as “removing unwanted species while supporting more desirable ones, drilling wells to water wildlife, and imposing fire management” all vastly effect and change the natural world, creating human constructions similar to “Disneyland.” Thus rather than leaving nature as it is, conservation tactics emphasize the anthropocene era of the planet.

Unlike common tropes about the fragility of nature, Karieva points out that nature is in fact very resilient and adapts to human interference. Wildlife is “thriving” around the Chernobyl plant which leaked radiation while “coyotes roam downtown Chicago,” Karieva writes. All of these examples of the resilience of nature and its constant adaptation to humans shows how nature is thriving in this anthropocene era.

I agree with Karieva’s interpretation of the world, as one with “no wilderness,” where “nature is resistant rather than fragile,” and where “people are actually part of nature and not the original sinners who caused our banishment from Eden.” When thinking about nature in such a way, one can certainly apply the anthropocene era to this time period. Humans are shaping nature and it is a dynamic force “in our midst rather than far away,” as Karieva puts it.
