A Green Antarctica?

There’s a bit of a dilemma happening in the Antarctic. That is, besides the fact that the glaciers are melting at a rate of 49 billion tons of ice each year. 

The issue is more of a moral one. Scientists largely agree that global warming is real, and it is a problem that will have catastrophic impacts on our world if left unchecked. The glaciers in Antarctica are certainly melting: it is entirely possible that in the next 200 years, the sea levels could rise up to 10 feet. In the past 200 years, sea levels rose by only 7 inches, and that was considered drastic. Coastal cities such as Venice, Boston, Miami, New York, and Mumbai would incur significant economic and physical damage, mostly stemming from a chronic flooding issue that would be difficult to control. Global warming, and therefore the melting of the glaciers, is caused by the greenhouse effect. The two major greenhouse gases are carbon dioxide (CO₂) and methane, and they form a layer of our atmosphere. As the light from the sun hits Earth, it reflects as infrared Screen Shot 2015-02-27 at 10.02.40 PMradiation. Most of this then exits the atmosphere, but some of the energy is contained by the greenhouse gases and continues to warm our atmosphere. The more greenhouse gases we emit, the more energy is contained and the warmer our atmosphere becomes. Obviously the concentration of greenhouse gases in our atmosphere has become overwhelming, as the glaciers in Antarctica are melting at a pace over five times faster than was predicted by scientists, when they should not be melting at all. The glaciers melt from the bottom up: first the water beneath them warms from the general temperature increase in the atmosphere at large. This, in turn, warms the ice and causes portions to break off, which then continue to melt in the water. The newly exposed ice then makes contact with the warmer water, and the glacier continues to melt.

So what is the dilemma? Surely all scientists would prefer that the glaciers stopped melting, even refroze. However, for botanists and plant biologists, the melted glaciers and warmer climate have some other affects that might even make global warming a bit alluring: plants are growing more, and better. This provides an opportunity to study the plant life of Antarctica in a way that has been previously impossible. Therein lies the conundrum: melting glaciers would increase the plant and animal life in the Antarctic, an exciting prospect for scientists in that area. The repercussions, however, would devastate many heavily settled cities as well as the ecosystems of both the ocean and the coastal areas.

Antarctica Glacial MeltingI think that while the prospect of finding out more about the ecosystems that could arise in the melted absence of the Antarctic glaciers, the damages to our civilization and other ecosystems would be too great a blow to justify even hoping that the glaciers continue to melt. The fortuitous discovery of further information on the Antarctic plant life is possibly something to ease the pain of the devastation of global warming, but it certainly does not justify perpetuating our current cycle of CO₂ emissions and pollution. We must continue to work towards a greener, healthier, less melty world.

Its Hard Not To Care When There Is So Much Smog In The Air

Living in New England, we have all encountered several blizzard warnings in which we are advised not to leave our homes. But can you imagine not being able to leave your home due poor air quality. For many of us this is unimaginable. How could the air quality within a whole country be so poor that one could not leave their home? For me, I actually lived through a smog epidemic during the summer of 2013 (Figure 1). This epidemic was so bad that the government made it illegal for individuals to leave their homes for about 3 days. Smog and excess air pollution is a chronic problem in Asian countries. This week I decided to dive in deeper and truly understand how smog build up occurs and why we see it so often in Asia.

Smog by definition is the combination of smoke and fog. Smog is a black haze comprised of a mixture of pollutants (Figure 2). But how exactly is smog created? As previously mentioned, smog is essentially a combination of pollutants in the air. When these pollutants are burnt the fumes are then released into the air.  These fumes come directly from things such as heavy traffic, high temperatures, sunshine and calm winds.The smog we see today is called photochemical smog. Photochemical smog is when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Examples of nitrogen oxides include car exhaust, coal power plants, and factory emissions. Examples of VOCs are include gasoline, paints, and many cleaning solvents. When the sunlight hits these particles it sparks the creation of fumes thus creating smog. Asian countries tend to have high populations thus resulting in an increase in the number of automobiles and heavy traffic. In addition, Asia being located near the equator makes for high temperatures and plenty of sunshine. These factors double the effects of smog and amplifies the effect. 

Figure 2


Smog can be extremely detrimental to ones health and in some cases it can be fatal. Smog gives off an immediate effect and theres no gradual build up. Smog can cause minor health issues such as a cold and pneumonia. Although this is the case, smog can also be responsible for major health issues such as lung cancer. Smog is most commonly known for causing irritation  in the eyes and increasing the difficulty to breathe (figure 3). Smog also deteriorates plant life. With several pollutants in the air, this makes it difficult for plant life to prosper and continue to grow. More often than not plant life can completely die as a result of smog. 


So what can you do to help? There several small actions one can do to reduce the amount of smog emitted in urban areas. First and for most, avoid driving if it is not necessarily. Try walking, carpooling, and or using bikes if everyone tries to do this smog emissions will slowly begin to decrease. In addition, fill your automobile with gasoline during the cooler hours of the day; this prevents gas fumes from heating up and producing ozone. Finally, if one cuts down on gas powered appliances and uses electrically powered appliances in stead this will also reduce the amount of smog.

The smog epidemic personally effected me and I am fearful that the problem will increase if we dont do anything about it. This problem can be reduced as long as we are aware and try and put forth our best effort to reduce the number of gas powered appliances we use!!! What will you do to reduce the effects of smog on our community?

Just Green Enough: A Compromise of Equality & Sustainability

The lack of environmental justice in American society is now being linked clearly to an issue prevalent in urban areas: environmental gentrification.

Environmental gentrification is the process of affluent populations moving into low-income neighborhoods and therefore changing the culture and demographics’ of that neighborhood.   This change generally leads to the displacement of the low-income population, as the neighborhood is no longer affordable.

The Environmental Protection Agency (EPA) released a guiding document detailing the organization’s intention to “incorporate environmental justice into its decision making processes.” (PERC) Meaning, the EPA is now taking into account the way in which pollution generally impacts the poor more significantly than the affluent. A disturbing example of such is illustrated in a “1983 study showing that hazardous waste landfills in the Southeast were almost entirely located in low-income, minority communities” (PERC)

This ruling of the EPA seems like a good thing. It means making low-income and historically disenfranchised neighborhoods cleaner and more environmentally friendly. It means upgrading low-income neighborhoods with things like LEED-certified green buildings, and bike lanes.” (Grist) LEED stands for Leadership in Energy and Environmental Design. There are different levels of LEED certification based on a point system. Any LEED certified building, is to a certain extent, energy efficient. A LEED certified building could have solar panels, harnessing sunlight to create electricity or heat. Essentially, the building’s design is geared to use the least amount of energy possible. Bike lanes would contribute to the fight against climate change, as it offers an alternative to driving or public transportation. Climate change is in part attributable to greenhouse gas emissions. Cars, when in use, emit greenhouse gases. These greenhouse gases range from carbon dioxide to methane. They build up in the atmosphere and block infrared rays from leaving, effectively heating the earth. This process is called the greenhouse effect.  Figure 1 illustrates this occurrence.

Figure 1:


Upgrading these neighborhoods would not only be environmentally friendly but also aesthetically beneficial to the community. Unfortunately, these improvements can lead to the displacement of the population it was geared towards helping.

Sprucing up a neighborhood with nifty environmentally friendly upgrades can trigger gentrification. Logically, if a historically “bad” neighborhood becomes cleaner and more “green” it will attract a new population. A population that can afford to take into account these upgrades. H. Spencer Banzhaf describes this occurrence aptly when he says:

“Residents who moved into dirtier communities tend to place a higher priority on low-cost housing than on the environment. Cleaning up the environment may increase those costs by more than their willingness to pay, as wealthier households bid up property values. As poor residents are more likely to rent their housing, they stand to lose from these increased housing costs.” (PERC)

Though environmental gentrification may be excellent for the environment, it’s not always ethically right. For example, in the 1990s, Pilsen, Chicago was an unsafe and predominately Hispanic community. “In 2012, however, the Chicago Department of Transportation finished upgrading two rundown streets by rebuilding them with recycled materials, permeable pavers, green streetscaping and sustainable stormwater runoff solutions.”  in Pilsen, Chicago. The neighborhood is now considered to be one of the ‘greenest in America’. (governing) Unfortunately, the rent prices are now soaring, displacing the low-income population that once resided there. Figure 2 shows a street in Pilsen, Chicago.

Figure 2:


Fortuitously, a compromise between both displaced inhabitants and the environment can be found in the idea of making neighborhoods “Just Green Enough.” Meaning, “to make a neighborhood more livable, without triggering gentrification.” (governing) There are two main components to this idea, the first being to make environmental improvements to the neighborhood without disturbing the identity of the neighborhood. The second being, allowing the community to be involved in making the neighborhood more sustainable. In addition, when a neighborhood is undergoing improvements, taking certain precautions, including local job training and rent subsidies, to prevent displacement. (governing)

Environmental justice is inevitably tied to issues of social justice, as the environment dictates the circumstances of its inhabitants.  The “Just Green Enough” initiative is a perfect example of the connection between the two. More importantly, however, making neighborhoods “Just Green Enough” means a more sustainable and equal environment and society.








Solar Energy: Abundant, but Inefficient!

This week I read an article from the University of Colorado website, “Solar Power”, which focused on the abundance and cost of solar energy. What intrigued me about this article was its description of how much solar energy is available, but not really useful to us now. This is due to the fact that the solar panels are simply not efficient enough. However, there is so much solar radiation in our atmosphere, the article claims, that we have 16,000 times our current needs of energy available to us. The only problem is that we cannot efficiently convert solar energy to electricity, or store it cheaply. This class has looked a lot at new technologies springing up around coal, oil, and other fossil fuels. Coal is very dirty, and hydraulic fracturing presents many dangers of its own as well. In fact, just last week, a train carrying oil from a fracking industry, blew up in West Virginia. This was because it was carrying both coal and oil, which are polluted and non-renewable resources. People around our country are praising the fossil fuel industry for bringing the cost of gas down in recent years. On the other hand though, this article actually informed me that there is far more renewable energy available from the sun than we will ever need. Our current problem in this area comes from photovoltaic panels (See below in Figure 1)

Figure 1: Active Solar Photovoltaics:

A solar panel uses two layers of silicon with different charges, sandwiched between other kinds of metal to produce an electric current from sunlight. Right now, most solar panels available are only 10% efficient: if the panel absorbs 100 joules of sunlight energy, it only produces 10 joules of electric energy. Therefore, the technology is also expensive! The article shows how 1 kilowatt hour of electricity from coal can cost as little as 10 cents, and the same electricity from a solar panel can cost 50 cents, or as much as 85 cents on a cloudy day.

There has been such a focus of money and energy on coal and oil recently. If those same resources were put towards solar efficiency, solar panels might look a lot more attractive to consumers, and we might be able to tap into the vast resources from the sun.

From Cotton Field to Vagina to Landfill: The Story of Tampons and Other Sanitary Products

Wait, My Menstrual Cycle Is Contributing to Environmental Degradation?

I know this not a topic that everyone wants to talk about. However, it has been a fact of life since the beginning of time. The average woman menstruates for 38 years in her lifetime. Unfortunately, in today’s world, 38 years’ worth of menstrual cycles translates into a lot of waste and energy. To be exact, there is approximately 62,415 pounds of sanitary products that end up in landfills[1]. Not to mention the countless tons of fuel that goes into producing these necessities. The truth of the matter is that sanitary items are one of the most unsustainable used products. In North America, over 20 billion pads and tampons are only used once before they are tossed. [2] But how exactly do sanitary items hurt our environment?

How the Waste Affects the Environment


Since most pads and tampons are made up of conventionally produced cotton, there has already been damage done before it even reaches the store self. Conventional cotton farmers usually treat the cotton with toxic pesticides such as aldicarb, phorate, methamidophos and endosulfan[3]. These chemicals are harmful to the people working with them and wildlife. Once sprayed, these toxins often move through the air to other nearby communities contaminating water sources, killing soil micro-organisms, bees, and other beneficial insects.[4]

This image displays all of the toxic chemicals that can be found in pads.

This image displays all of the toxic chemicals that can be found in pads.

Also, most of the cotton is then bleached with chlorine gas.[5] Once the cotton bleached chlorine enters a landfill, it becomes deadly to organisms living in water and the soil.[6] Another harmful chemical found in most sanitary products is called dioxin. Dioxin is a carcinogen that over time accumulates in the food chain. Within an organism it can trigger biological effects such as hormonal disturbances and alterations in cell functions[7] as well as adding to the risk of cancer, diabetes, heart disease, high blood pressure, and liver damage in humans.[8]


It’s not only the cotton that’s harmful, but it is also the plastic applicators and the plastic wrapping. The manufacturing process of producing these disposables consumes a lot of energy[9] and nonrenewable resources which contributes to global warming. Most disposable pads and tampons are made from 90 percent plastic derived from crude oil.[10] When crude oil based plastics reenter the environment it releases large amounts of toxic pollutants which ultimately leads to devastating damage to wildlife and the natural landscape.[11] Combined with other super absorbent materials, the manufacture of sanitary items releases greenhouse gases: nitrogen oxide, sulphur dioxide, and carbon dioxide which are causing our planet to heat up.[12]


I too was shocked to realize that not only are these feminine products not good for the environment, but they are also harmful to my own health. Fortunately, there are healthier and eco friendlier alternatives. Natracare is a company that produces organic chemical-free pads and tampon. These products are more eco-friendly because they are bio degradable and do less damage to the environment since they are bleached without harsh chemicals or sprayed with pesticides.[13]

However, the best alternatives are menstrual cups or reusable pads which have life uses of 15 years. Products such as the Keeper menstrual cup claims those 40 years’ worth of disposables can easily be converted into as few as four menstrual cups![14] Similar to The Keeper, Lunapads claim to divert more than 1 million disposable pads and tampons from landfills every month. Over the course of one year, that is more than 12 million less feminine products contributing to environmental issues. [15]

This image shows how 4 menstrual cups can replace a truck load's worth of sanitary waste.

Bringing Beauty back into Green

It is projected that by 2088, the world will run out of fossil fuels. We could even deplete our oil by 2040, or our natural gas by 2060. This may seem inconceivable, but taking into account the rate that we are guzzling energy, and the fact that this rate is constantly increasing may means that our lights will go out too soon. But do not fear! Renewable energy is forthcoming. There will never be a day when the sun is not shining, or the wind is not blowing, or at least, not in the near, foreseeable future. Renewable energy has minute if any emissions that contribute to global warming, improves public health and the environment, and is inexhaustible. Yet today, the world still uses 81% fossil fuels, with 34% oil, 21% natural gas, and 26% coal/peat. All the renewable energy used in the entire world is less than even one of these resources, at only 13% usage. The advantages of using renewable resources are many, and for a better future, a change needs to be made. So why is it that we still use so much nonrenewable energy?

The world's energy consumption by resource

Fig. 1: The world’s energy consumption by resource

     There are multiple reasons. First, these innovations are pricey. The average home solar system costs a little over $10,000. It’s hard to justify the installation of solar panels, which includes paperwork, construction, and a whole load of hassle, to lower your energy bill in the long run, when you oil bill is already only a few hundred dollars per month. The other downside to renewable energy is that it can be an eyesore. There have been countless complaints from angry citizens who believe that wind turbines have ruined their community’s scenic landscapes.  One man commented his on experience with the installation of turbines, stating “One of the most troublesome problems with the proliferation of industrial wind projects in Maine is their encroachment on the “treasures” of the state that we have purchased to protect for future generations. […] We have leveraged with these funds millions of dollars more from other sources to preserve places like the Mahoosuc Range, Rumford Whitecap, Bald & Speckled Mt, Tumbledown & Jackson Mt., and Schoodic Mt.  All these wonderful places are being surrounded by wind turbines.”

Fig. 2: Wind turbines on a scenic landscape

This problem with wind turbines is even plaguing Scotland, with the Daily Mail reporting that “They are famous Scottish landmarks which have withstood wars, weather and centuries of change – but they could not escape the Scottish Government’s green agenda.”  And I agree: these turbines placed around beautiful mountain ranges, historic sites, and rolling hills are certainly an ugly blot on the landscape.

Fig. 3: The Daily mail comments “The View? Gone with the Wind”

Fig. 4: There are even plans of building turbines “taller than the London eye” surrounding Loch Ness

This leads people to despise the idea of renewable energy. Eventually, the turbines will be disposed of due to unhappiness of the people. This only digs the world deeper into the hole it’s already dug much into: we need renewable energy to be used more, yet it’s becoming disliked, so it’s not. But a new option is emerging, something that blows all other ideas for clean energy implementation out of the water. What if, instead of attacking the world’s energy problem with boring, ugly white turbines, or a black, brooding expanse of solar panels, people were to approach this problem from a different angle? Instead of only productivity, why not combine productivity and beauty to create an efficient masterpiece?

 Yes, there is a solution!

Innovative companies are turning ugly wind turbines into something beautiful. They are, in essence, taking the meaning of the word “green” literally. The first of these companies is NewWind, based in France. NewWind has created an artificial Wind Tree, which uses tiny leaf-shaped turbines to harness the power of the wind. They can utilize anything from the smallest breeze to a giant gust of wind. They are completely silent, as well as modern, sleek, and pleasant to view.

Fig. 5: French people observing the Wind Tree

They produce 3.1 kwh of energy.  Though they are not quite as efficient as your typical turbines, which produce anywhere between 5-10 kwh or more, nonetheless, they have been praised and lauded by countless websites and magazines. They are currently are being used in Brittany, France and are set to be installed at the Place de la Concorde in Paris in March, 2015. In my opinion, they are most certainly energy made beautiful.

Vid. 1: Above is a short video showing the Wind Trees in action

Another emerging invention is the Power Flower created by NL Architects.  The biggest advantage of this power flower is that it minimizes space needed to function. Instead of a huge turbine, it’s a thin, lean build that utilizes vertical turbines for maximum space-saving.

Fig. 6: Wind turbines in comparison to Power Flowers

Just like the Wind Tree, it is basically silent and can absorb wind that blows form any direction. Though there are many plans for the Power Flowers to become domestic energy solutions, there have not been many installed just yet. But, the plans look incredibly promising. This is yet another example of a minimalistic, clean, attractive build that will certainly be admired by customers.

Fig. 7: A plan showing how the Power Flowers could be seamlessly integrated into the landscape.

Lastly, the Gardens by the Bay in Singapore is an example of an already functioning innovation that has smoothly merged into Singaporean culture. There are many words to describe the Gardens by the Bay, but the first that come to mind are awe-inspiring, breathtaking, and incredible. They are unbelievable feats of architecture, and look like they have popped out of a futuristic movie. They do not make people turn away, but rather, are an attraction that draw citizens and tourists alike near.

Fig 8: A beautiful shot of the Gardens by the Bay

But these Gardens are more than beautiful. As well as spectacular, they are also incredibly efficient. The trees are layered in solar panels, act as cooling ducts for nearby conservatories, collect rainwater, and de-humidify air before this cooling.

Fig 9: The Trees up close

Singapore is filled with high rises, skyscrapers, and a dense city landscape. Their initiative should be one that is followed by cities around the world: to transform their community into a greener place, both physically and energy-wise.

The world is transforming into a viridescent place, and a more beautiful one, too. I believe these three projects, the Wind Trees, Power Flowers, and Gardens by the Bay, will motivate people to become more excited about energy efficiency, rather than despising of it. They will look forward to the beautiful installations, and benefit from the clean energy that they produce. It was once believed that the stark white wind turbine, or black expanse of solar panels was the future, but I believe that real future is the combination of beautiful architecture and renewable energy.

CO2 Emissions

We live in a world that thrives off the burning of different fossil fuels and the constant use of electricity.Through the burning of fossil fuels and use of electricity, CO2 is emitted into the atmosphere. This means that we basically live in a world that thrives off the emission of CO2.   It’s a sad reality that is unfortunately true.  Everyday, people are emitting ton CO2 into the Earth’s atmosphere without realizing the negative effect the emissions have on human and animal lives. CO2 is already present in the Earth’s atmosphere,which raises the question as to why it can and does have so many negative effects on human and animals, if the organisms have already adapted to its effects. Have you ever heard the phrase, too much of a good thing can be a bad thing? That is precisely what is happening with the amount of CO2 present in Earth’s atmosphere. Through human activities, the amount of CO2 present in the Earth’s atmosphere has increased greatly.

In 2012, 82% of all greenhouse gases emitted into the atmosphere, in the United States was CO2 emitted through human activity. One main source of CO2 emission is through the use of electricity. Electricity is used to power homes, commercial buildings, and everyday appliances. The amount of energy that we as humans use in a day is ridiculous. We use electricity to charge our phones, to charge our laptops, to power our lights, and many other things to help our lives function smoothly. Electricity is generally generated through the combustion of fossil fuels especially the burning of coal. The burning of coal then emits CO2 into the atmosphere and in the U.S. the amount emitted was 38%. Another way that we as humans emit CO2 into the atmosphere is through transportation. By driving your car to the doctor or taking the train to the town square, you are emitting CO2 into the atmosphere. Through the burning of gasoline and diesel both of which are fossil fuels, more CO2 is emitted into the atmosphere. Transportation accounts for about 32% of all CO2 emissions in the United States.

The effects that CO2 has on organisms at times can be deadly. The increase in CO2 emissions is one of the main reasons global warming is occurring. The rate at which CO2 is being emitted into the atmosphere, will eventually cause  the Earth to be too hot to live on. It will also cause the Earth to experience extremer weather conditions. Due to the climate the change and increase in temperature infectious disease will be able to spread faster. This is because the disease will be able to live and thrive longer in warmer temperatures. Another effect is that there has been an increase in acid rain that affects mainly marine animals. The pH level in oceans is rising as CO2 emissions increase. As the pH level increases, the harder it will be for organisms to adapt to the new environment and some if not most will die out.


global warmin

So the question that I seek to answer is why are we as humans still emitting these gases into the air if we know that they are harming animals and us.
