Flower Farms
Perhaps it's just me, but humans plant, raise and buy flowers for their aesthetic appeal. Flowers are beautiful, artistic, even. We buy them to celebrate accomplishments, to communicate affection. Gifts of flowers are loaded with sentiment and meaning. It's more than just about the blossoms that will fade after a week or so, it's about expression, it's about bringing Nature's artwork indoors, into our lives.
If this is true, then it's seems paradoxical that the symbols of our expression, of Nature's beauty, would be farmed as commodities in neat and uniform rows, completely removed from any natural setting. No flower garden here, just a means to an end. Certainly, flowers have been commodified since we've been buying them, but the act of ordering or purchasing flowers for a loved one rarely seems like a commercial one to the individual. It's an act of love, right? Not one of consumerism.
This image makes very clear the system in which even that purchase of love contributes to, and that those garden-variety flowers are mass produced with the same pesticides and fertilizers as those other commercial crops. Flowers as crops is an idea not widely recognized, I think.

Noise Pollution Evolution
The study was performed by the University of Sheffield's Julie Schroeder, who found that loud noises drown out communication between mother house sparrows and their chicks, including the calls chicks make to beg for food. Only a handful of other studies have examined the effect of loud noises on songbirds mating and nesting habits, though none have quite tackled the serious maternal questions raised long ago in Dr. Seuss's seminal work, Are You My Mother? Sheffield's study is also made unique by the fact that she focused on a well-known group of sparrows living on Lundy Island, in Devon, England. These sparrows regularly trade swap their eggs among nests, which results in some parents raising chicks they're not related to (and I find myself wondering if all sparrows do this, or if it's just a British thing). This kid-swapping helped researchers separate the effect of a sparrow's parentage from the effect of its environment, just in case the genetically weaker sparrows were somehow more prone to doing something stupid... like live next to a roiling electrical generator, which is exactly what some of them were doing.
The generators on Lundy Island (built in 2001) run continuously from 6 to 9 pm and emit 70 decibels of noise. Schroeder compared the nest boxes located in the generators' noise zone to nests located in a quieter zone. She found that, while the noise has no real effect on the health of adult birds (female birds could even lay the same number of eggs), it did adversely affect their offspring. Though chicks in quiet areas had a 25 percent chance of living long enough to fledge (such are the harsh realities of birdy life), the chicks in noisy areas had only a 21 percent chance. Plus, those urban chicks weighed less than their country counterparts, most likely, Schroeder believes, because mother birds visited their chicks less often and provided them with less food.
The fact that adult birds seemed in fine health led Schroeder to single out noise as the culprit in the weakness of urban chicks, since, say, if air pollution had been stunting chick growth, adults would have been unhealthy too. Researchers suspect these findings may help explain the house sparrow's sudden disappearance in Western Europe and North America. "If what we suggest takes place in big cities too," she says, "it is likely to play an important role in the sparrow population dynamic, and is probably one cause of the dramatic population crash that we are currently observing." Discovery Magazine reminds us that the exact cause of the chicks' undernourishment is still uncertain — there may very well be a barrier between mother and chick communication in urban areas or loud noises may scare off insects the birds eat.
It's probably pretty important, though, for us to keep track of the plight of these songbirds, lest -God forbid!- the pigeon become the only bird we can look forward to seeing on our stroll to work in the big city!

He's Armed and Dangerous... and Developing New Stockpiling Tactics!
Three years ago, a stone-throwing chimpanzee named Santino shocked the research community by providing some of the strongest evidence yet that nonhuman animals consciously plan ahead. Santino, a resident of the Furuvik Zoo in Gävle, Sweden, calmly gathered stones in the mornings and put them into neat piles, apparently saving them to hurl at visitors when the zoo opened. Scientists described his throwing rocks as part of angry and aggressive "dominance displays," (but honestly, if I were on display in a zoo, I might stoop to flicking pebbles at ogling passerby as well. If I were lucky, maybe a terrorized patron would drop that unfinished smoothie in horror as they left).
Some factions of the scientific community, however, were not entirely convinced, suspecting that there might be simpler explanations for seemingly humanlike behaviors exhibited by the chimpanzee (immediately, what comes to my mind is whether our own "humanlike behaviors" are not due to some similar "simpler explanation," but I digress...)
In the new study, primatologist Mathias Osvath primatologist Elin Karvonen report new observations of the rock-hurling primate. Santino's first attempts to throw stones during 2010 came during the zoo's May preseason. As a zoo guide led visitors toward Santino's island compound, the chimpanzee began to engage in a typical dominance display: screeching, standing on two feet, and carrying a stone in his hand. The guide and the visitors retreated before Santino began launching the stones, and then advanced again for a total of three approaches. When the people returned about 3 hours later, Santino advanced toward them, holding two stones, but he did not act aggressively, even picking up an apple from the water surrounding the island and nonchalantly munching on it. But when Santino got within close range, he suddenly threw one of the stones. (It didn't hit anyone.) Haha! Feinting disinterest to strike when they least expect it!
The next day, Santino was observed pulling a heap of hay from inside his enclosure and placing it on the island close to where the visitors approached. He put several stones under the hay and waited until the group returned about an hour later. Then, without performing a dominance display (sneak attack!) Santino pulled a stone from under the hay and threw it. Later, he pulled a stone that he had apparently hidden behind a log and tried to hit the visitors with that, as well. Over the course of the summer, Osvath and Karvonen observed repeated episodes of this behavior, and also recovered stones that Santino had hidden under hay or logs, racking up 114 days of observation. They recovered a total of 35 "projectiles" that Santino had apparently concealed: 15 under hay heaps, 18 behind logs, and two behind a rock structure on the island.
The researchers conclude that Santino deliberately engaged in deceptive concealment of the stones, and that this was a new, innovative behavior on his part: Before 2010, Santino had never put stones under hay piles or behind logs. Yes, the tactics must evolve lest your opponents predict your next move! This innovation, the team argues, is further evidence that Santino plans ahead for how he will react to the visitors' approach to his compound, and that this is inconsistent with skeptic interpretations that he cached the stones for some other reason and then just happened to have them at hand when he got mad. By hiding the stones and then trying to deceive zoo visitors into thinking that his intentions were innocent, Osvath and Karvonen argue, Santino was actually anticipating and planning for a future situation rather than simply responding repetitively to a past one.
The killjoys, however, are still not entirely convinced. The study has been deemed "provocative," but insists that further experiments with more animals are needed before Santino's behavior can be interpreted as true advance planning. Some claim that the authors should have tried additional tests such as putting a hay pile in the compound themselves and seeing if the animal still persisted in carrying hay, or putting the hay piles in unfavorable locations for throwing.

Futility is in the Mind of the Beholder
Beavan concedes that much environmental damage is done by large corporate entities, many of whom would rather the citizen take personal responsibility for environmental change, lest the company be blamed and held accountable. Certainly such corporations should be held accountable, and if forced to atone for their environmental sins, improvements would be far and away more substantial than any one household’s. Personal responsibility, however, requires something of the individual that scapegoating will never achieve. The first hurdle to improving the environment is not forcing corporations to internalize the environmental costs borne by the world. The first hurdle is overcoming apathy.

Befuddled Bumble Bees
Finally. Scientific evidence to prove what we knew all along! (Please note the sarcasm)
A spokesperson from Department for Environment, Food and Rural Affairs (Defra) said the new research did not change the government's position. 'The UK has a robust system for assessing risks from pesticides and all the evidence shows neonicotinoids do not pose an unacceptable risk to honeybees when products are used correctly. However, we will not hesitate to act if presented with any new evidence.'

The Unimpressive
I once watched a little girl in the park with her father. She was about 3 years old, maybe 4, dressed in a white coat with a fuzzy collar and puff-ball drawstrings. At her feet were several sparrows, hopping on the asphalt and pecking at the ground to gather the breadcrumbs that her father had scattered on the ground.
I will never forget the look on that little girl's face. Eyes wide, mouth open, forming a perfect lowercase "o." That child was sucking in the world like a dry sponge, enthralled by the birdies bouncing inches from her white maryjanes. I think this is the kind of moment Barbara Kingsolver is reflecting on in her essay, The Memory Place. She calls these instances of "gasping," exclamations of wonder at the little things.
It is in my experience that such instances exponentially decrease with age. One might argue that this phenomenon is a consequence of acclimation, or even overexposure. Indeed, if one is treated to the luxury calamari and champagne every day, the experience loses its novelty and becomes commonplace. I am of the opinion, however, that the true reason for this rapid decline in childlike wonder is due instead to a culture and social climate which forces value judgments upon our experiences and delineates an appropriate way to regard them. What was once a soft sunburst on a green stem becomes nothing more than a lawn weed once we "know better" and to celebrate a lawn weed simply isn't becoming -rather, it is looked upon as a sign of ignorance.
This jaded persona, I feel, not only creates an unenthusiastic and vapid society, but inhibits the exultation of that which may well be worthy of praise. That is to say, just because social pressures drive wildflowers from front lawns, doesn't mean society has it right. In addition, in inhibiting our willingness to allow ourselves to be impressed by the small and commonplace, we not only devalue but may also endanger what we find unimpressive. For Kingsolver, this is the creek, muddied and neglected for its being only a common creek and not something more exotic or pristine. It is the mourning cloak butterfly which, for some, may only excite when believed to be rare and fail to amaze when proven to be otherwise.
One might argue that such is the natural progression of personality. Only when we become more worldly, become informed of the “true state of things,” can we form our opinions of value. However, our "experienced perceptions" may not be the golden standard. Many a species has gone extinct due to neglect by peoples who failed to attribute to it any value -and those species that have managed to survive the installment of highways, cities and suburbs rarely receive any credit for their amazing feat. It is my opinion that perhaps "childlike wonderment" needn't be so childlike. That is to say, perhaps if it weren't something attributed to only inexperienced and naïve children, a quality not only maintained into adulthood but encouraged by society, we might have a greater appreciation for the world we live in.
At the end of her essay, Kingsolver ponders the fate of places undervalued by humans for their being conventional, unexceptional or already "tainted" by humans. This is a question only recently being addressed by the environmentalist community. There do exist -though this existence is debatable- untouched, pristine places of wilderness that need be protected and preserved. However, there are many more places that have been touched and these merit no less care on the part of humans. Though the tendency is to categorize, to designate human dwellings and nature's territory as separate, there are no separations to be made. Try as we might to create man made cities, trees and flowers grow from cracks in the sidewalk, rain falls from the sky, and earthworms burrow underground. Nature's presence is just as strong in urban areas as in rural, in developed regions as in wilderness.
The danger of suppressing those moments of wonderment, those "gasps," is the consequential devaluing and neglect of nature that is right in front of our faces. This is the experience of nature that we have the most potential to interact with and to form relationships with. Additionally, it is the part of nature which we can most immediately and strongly impact -positively or negatively. So why not create positive changes?
Urban ecology is a relatively new branch of environmental study which seeks to do just that. Urban ecologists first recognize that there is ecology to be found in urban areas, that there are species of plants and animals that have become just as well adapted to urban and suburban areas as humans. Rather than scoff at squirrels and goldenrod as being a dime a dozen, the urban ecologist is in a position to admire the complex systems able to evolve in areas of urban development as well as seek ways to augment them.
Urban areas and inner cities are not lost causes. Only when we perceive them as such is there harm done. Instead, there are many ways we could adapt our "civilized" infrastructure to better accommodate the wonders of nature right under our noses.
If only we would allow ourselves to gasp once in a while...
Ownership and Responsibility... and some tears
On Monday, February 20th, I saw part of a documentary called Sludge, about a coal sludge impoundment in Martin County, Kentucky, and the devastation it brought to the community. Breaking through the underground mine below, the impoundment propelled several million gallons of waste material down hillside and tributaries until stream beds and waterways were thoroughly buried, contaminated and oozing with toxic black sludge. Worse than the Exxon Valdez oil spill (considered one of the worst ever environmental disasters by the EPA) this inundation of black waste spoiled the water supply for over 27,000 Kentucky residents and killed all aquatic life in Coldwater Fork and Wolf Creek.

Cruise Liner Blues
Oils rigs are usually getting the blame for wreaking environmental havoc on the high seas, but in light of recent evens involving a certain cruise ship, I thought I would comment on the nautical polluters not frequently in the news... until someone tips it over.
according to the EPA, cruise ships were involved in 87 confirmed illegal discharge cases in the years from 1993 to 1998. Most of these involved the accidental discharge of oil or related substances but a few cases involved large numbers of illegal discharge incidents.
What sort of "normal waste discharges" are there?
2. Gray Water (shower, sink, and galley water): A typical cruise ship is estimated to generate up to one million gallons a week.

Bringing Down the Stereotypes
