My overall reaction to the presentation was that it was very
long, but interesting. Atlanta has had a recurring history of droughts, but actually
Atlanta is currently in a water crisis. The presentation mainly focused on the
factors contributing to the water shortage, and how we can even stop it. Most
states receive most of their water from water shed, and rainfall, but lately
our demand has progressively exceeded our supply. Atlanta is an exception
though because we receive the smallest amount of water shed than any other
metropolitan area. Hard manmade structures in Atlanta have prevented the absorption
of rain, so our water supply has diminished significantly. A legal issue with other states has also
decreased Atlanta’s water availability. For 20 years Atlanta has been in a
dispute with Alabama and Florida over the operation of dams. Fortunately Atlanta
has come up with long term sustainable solutions to combat our growing
population and diminishing water reserves. We have adopted various strategies
to save water. These strategies include fixing leaks, retrofit plumbing, the
utilization of water efficient appliances, and even harvesting rain water. The
culmination of these efforts will hopefully help restore Atlanta’s water
supply. We cannot afford to waste water through our development, but if we work
together to live sustainably we can begin to reverse the effects.

Facing the Freshwater Crisis
The contingency in the world's water supply is very real as detailed in the article "Facing the Freshwater Crisis" by Peter Rogers. The article focused on the availability of freshwater in the world and the factors contributing to its accessibility as well. The scarcity of water can be atrributed to global warming, faulty waste disposal, and even fertilizer runoff. This lack of freshwater can also lead to starvation, disease and even conflict. Freshwater is one earth's most valuable resources, if not the most valuable. Freshwater's importance is integral to the sustainability of the environment, and it supports both flora and fauna in ecosystems around the world. Unfortunately freshwater allocation is only accessible to those who can afford it, and because of this most underdeveloped countries and societies face dehydration at the rich's expense. Although freshwater is continually becoming more scarce due to periodic droughts of certain river basins there are solutions. Solutions such as virtual water is one of the many factors contributing to the conservation of freshwater that will help our environment.
Volcanic Eruptions-
The Tambora volcano in Indonesia erupted on April 10 1815 and lasted two days. It killed 92,000 people and resulted in tsunami's, disease and starvation.
The Krakatoa volcano in Indonesia erupted on August 26, 1883 and also lasted two days. It killed 36,000 people and resulted in a tsunami as well.
On January 10, 1997 a volcano in Congo erupted and killed hundreds of people who died from sudden lava flow.

TEDtalk "Box by Box"
In this TEDtalk video the speaker, Hans Rosling elaborates
on the dangers and solutions of population growth using boxes. This simple
utilization of boxes gave me true insight on what can really be done to combat
population growth. As he explained in the video, the main factors contributing
to dramatic growth is the gap between developing countries and developed
countries as well as child mortality rates around the world. If we can combat
these two facets of drastic growth then we will be able to stop the world’s detrimental
expansion. But we can only do this if members of the world work together. The
United States as a developed country needs to help lead the way and foster other
countries development. We need to send supplies such as medicine and vaccines
that will help young children in developing countries survive. Like Mr. Rosling
said, developed countries like America need to serve as a base, and with only a
strong foundation can the world begin to bridge the gaps.

“The funky bug population of San Francisco”
November 6, 2012
San Francisco’s bug population is as diverse and colorful as
the people that live there. Although the insect population is fairly steady, I
believe it does cover the topic of population diversity. Amidst San Francisco’s
lawns, bushes, and trees is a myriad of bugs that have a variety of colors and adaptations.
The velvet ant is a species that lives in San Francisco. This “ant” which is
actually a wasp looks like it is wearing a shag carpet. Other species include
the Buckeye Butterfly whose wings have a mixture other colors that culminate to
create a psychedelic motif. These bugs may not be breeding rapidly and
threatening San Francisco’s environment with drastic growth, but they do attribute
to the city’s overall biodiversity.
Cat Trouble in Toronto
“Toronto’s cat population booming”
November 3, 2012
A recent warm spring in Toronto has encouraged a drastic
increase in the cat population. Toronto has as many as 300,000 wild cats that
roam their streets, but the recent warm weather revealed a total influx of new
kittens that were admitted into shelters all over the city. Bceuase of that
recent increase shelters have reached full capacity and now programs have even
been implemented to trap, spay and neuter feral cats. The volunteer run program
has a trap and release approach, but upon spaying and neutering the cats they
have seen a 32% decrease in the cat population. The city of Toronto knows that
they cannot completely rid their streets of the felines but the new programs
have proved to be formidable and have dramatically hindered cat population
increase. This actually seems very reminiscent of a certain policy in China.
The people act as the government and the cats act as the people. Although the
program actually takes physically takes away the cat’s ability to reproduce who
says that China’s doing something different. They are just doing it mentally.

“Ireland experiences population growth”
November 28, 2012
Since 2009 Ireland’s population has dramatically increased. Three major factors have significantly contributed to Ireland’s growth: more affordable housing, fewer jobs, and cheaper rents. The combination of these factors has fostered exponential growth within the country and now the economy has began to suffer. Due to the recent and dramatic growth there has been a lack of maternity wards for deliveries and hospitals are struggling to make room for soon to be mothers. It is estimated that over the next decade Ireland’s population with grow by ¼! Although this baby boom has hurt Ireland in the short-run, it actually has some long-term benefits. The upcoming generation will be able to support the older class and the Irish state will have an easier time funding its liabilities. The benefits will have to wait though, because the present crisis at hand is more prevalent than the future benefits. Ireland is now trying to find ways to accommodate the future generations. In my opinion it is now a race to see if the exponential growth completely devastates Ireland’s economy and environment before the new generation is able to create beneficial opportunities for Ireland, or will the country have to implement controversial policies such as China’s “One Child Policy” to limit population growth.

China's Time Bomb
A) I would encourage population growth in Japan
with fertility treatments, enforcing healthier foods, and plans for larger infrastructures.
I would also change advertising techniques to encourage the familiar “nuclear
family”. I would not depict mothers as women confined to the household to do chores;
I would portray them more as a role model.
B) I would offer financial incentives and open more
and less expensive child care centers. I would also encourage scientist to work
on fertility drugs and research.
C) To delay economy collapse with a baby bust I
would encourage more marriages and try
to increase fertility rates, as well as lower healthcare and social security
rates, because there will be too few workers to support the elderly. I could
also loosen immigration policies so that more young people are allowed into the
country to foster economic growth.
D) No, the government should not be able to force retirement
when the overcrowding situation is dire. Abortion should be up to the mother
and only up to a certain point in the pregnancy. If overcrowding becomes a
prevalent issue the government should focus on expanding infrastructures and
tighten certain policies such as immigration.
E) Yes, I believe the government should offer
political asylum to Chinese women who wish to keep their babies. I believe this
will greatly benefit China’s population problem and maybe in future years help
lift China’s one child policy. I would
handle political implications by ensuring the people that the countries in
which the pregnant Chinese women are moved to are safe, efficient and more
importantly not overcrowded.

Easter Island + New England= Earth
Though the locations of Easter Island and New England are
very different their past history’s do have stunning similarities. Both locations’
landscapes changed dramatically overtime. In New England the plant community
underwent a drastic cycle that encompassed the death and revival of numerous
plants due to predators and even people. For example the goldenrod died and was
revived several times because of human intervention and even the intervention
of other plants. In Easter Island the plant life has been speculated on because
it was decimated because settlers cleared land and trees to plant gardens,
build canoes, homes and make fires. Can
we learn from not only the fate of Easter Island, but New England as well? My
answer is yes! Earth’s landscape currently changes at a rapid pace. Every day
we clear land for homes, parks, infrastructures, and stores. This alone is not
completely terrible. As we can learn from the history of New England human
intervention will not always destroy an ecosystem. Even though many of New
England’s plants habitually died off, its ecosystem proved to be resilient and
bounce back. But, an ecosystem will not always return to its prime if we are
clearing more than the ecosystem can grow. As proven by the history of Easter
Island we can destroy our ecosystem if we continue to ravage and demolish its
content. Easter Island should serve as an example of Earth’s ecosystem on a
smaller scale. We should learn not to completely leave our environment alone
but to limit our intervention with the environment, because a healthy ecosystem
has deaths. This does not mean that the ecosystem is dying, but it actually
means that it is healthy.

Biological Hotspots
Hotspots Defined
1.Norman Myers first coined the term “hotspots” in 1988.
2.To qualify as a hotspot a region must contain at least 1,500 species of vascular plants and it has to have lost at least 70 percent of its original habitat.
Hotspots in Peril
1.Habitat destruction
Predatory invasive species
Introduction of exotic plant species
Direct exploitation of species for food, medicine, and the pet trade
Severe decline of amphibians worldwide
2.The International Union for Conservation of Nature is the world’s oldest and largest global environmental organization, which compiles the Red List.
3.Yes, researchers have found that there is a relationship between hotspots and population density and hotspots and violence.
Conservation Response
1.Threatened species
Key biodiversity areas
Landscapes
2.Hunting
Direct exploitation
Disease
Predation by invasive species
3.Three conservation responses to specific-species threats are incentives and legislation to reduce hunting pressure, control of invasive species, and captive breeding, propagation, and re-introduction.
4.The biggest threat to species is the degradation and destruction of their habitats
5.The primary response to the biodiversity crisis should be the establishment and effective management of protected areas.

Aldo Leopold Reflection
Beneath our feet and even around our heads lies a world
which we may never understand. The quote by Aldo Leopold really made me think.
It is amazing that we may never learn everything that occurs within our own
environment. There may be a secret life of bugs, like the ones portrayed in
movies like Bugs Life and Antz or even special friendships between two animals
of two totally different species. It may be amazing that we may not notice or completely
understand what happens in our environment but according to Leopold this is not
unfortunate. I agree with Leopold. Completely understanding all of the salient
facts about nature takes the all beauty out of it. The mystery of nature is
what makes it so alluring, and like a mysterious and attractive woman we all
look twice to take in her beauty. If man
one day completely understands the ambiguity of nature then I imagine the world
would be completely changed. Man’s thirst for knowledge and boundless curiosity
has changed our world drastically. Like we learned in class, man created the
domestic dog through curiosity, so how will we react when all the mysteries of
nature are discovered. Will we get bored and completely neglect it or even move
on to conquer the natural environment of another planet?
Do raccoons plan their heist on garbage cans?
When squirrels cross the street is it just a game of
chicken?
Why do worms come out when it rains heavily?
What is cutting the lawn like for small bugs and plants?
How do other animals feel when they see road kill?
What are bees buzzing about?
How do trees feel when they are defaced?

Ted Talk: A Plea For the Bees
No other insect receives such mass marketing and attention
than the bee, but now all of that attention needs to be geared towards saving
them. In this Tedtalk video the speaker, Dennis vanEngelsdorp elaborates on the
recent decline of the bee population. Factors such as varroa mites and
disorders such as Colony Collapse Disorder have all contributed to the bee
population decline. Over the past
several years 36% of the bee population has disappeared because of these contributing
effects. Many beekeepers have just ignored this recent decline by just
importing and transporting bees across the country and from other countries.
This alone is not the problem. The problem is that we are not doing anything to
stop it. As stated in the video bees are major contributors to many of the
natural foods we eat daily such as jam, honey, and fruit. They help carry the
reproductive pollen that is essential towards the natural bloom of our environment.
As we learned in class today, the smallest action can have a large or multiple
impacts. If the bee population continues to diminish at its current rate then
we may not have much of the natural beauty and sweeteners that we have today.
It's hard out there for a nitrogen
Nario Nitrogen and his brother Naquan Nitrogen were the coolest but worst molecules at Sky High. They had run the school for years but the principle Mr. Lightning became fed up with their terrible antics. One day Mr. Lightning kicked the brothers out of school. They were both shocked by the principle’s decision and fell into a deep depression. They then found themselves on a wild journey. Both Nario and Naquan had hit rock bottom and their faces were literally in the dirt. While in the slums, they encountered a strange microorganism named Father Baron Bacteria, who convinced Nario that his brother was a bad influence and encouraged him to hang out with the hydrogen brothers instead. Nario, now reflecting on his pitiful life took Father Baron Bacteria’s advice and so began his new life under the name of Nario Ammonia. Nario Ammonia still felt something was missing from his new life, so Father Baron Bacteria intervened once again and paired him up with three oxygen members from the program. Nario ditched his old life and friends once again and became Nario Nitrate. As Nario Nitrate his confidence returned once more, so he looked to assimilate into his new life by finally finding a job and began working at the Legume Plant. Things were going great in the plant until one day when the plant was bought by a Dairy farm. Nario thought all was lost. He was just not cut out for the complex operations of the Cow Company. The company tried to keep him and they moved him throughout all four chambers of their business, but he just couldn't find the right fit, so the company fired and dumped him. Stinky and defeated Nario Nitrate reverted to his old self and even started hanging out with the hydrogen brothers from the program again. Nario Ammonia was just about to give up on life when Father Baron Bacteria who was a new microorganism himself had a change of heart and realized that Nario needed his brother to rise to new heights. Nario gladly returned to his brother and faithful Naquan excitedly took him back. Together the brothers got their lives together and returned to Sky High.

Endangered......
Arctic Fox
The Arctic fox’s habitat, the Arctic Tundra is wavering in
the balance because it is being extremely weakened due to climate change. Although
various species are threatened by considerable climate change, the arctic fox has
been threatened significantly more. Arctic foxes are not endangered in all
areas, but this doesn't mean we shouldn't do what we can to save them. They are
mainly endangered in Norway despite strict hunting rules. Hunting is not the
sole culprit for the arctic fox’s endangerment. Global warming has fostered
competition between red foxes and arctic foxes. The melting of ice in the
tundra has allowed red foxes to expand their hunting range into arctic fox
territory. Climate change has diminished the territory of arctic foxes, and
because of global warming they are literally “feeling the heat”, from shrinking
snow and ice cover.

The Climate of Denial reflection
Al Gore’s essay, “The Climate of Denial” illustrates how the
media and America in general is oblivious to the harmful effects of global
warming. As long, and dry as it was, the “article” did bring up some
interesting points. The analogy in the beginning almost perfectly demonstrated
how blind we are to our environment, and sometimes we are blind on purpose. Al
Gore elaborates on how Americans have been purposely blinded to the major
environmental issues. I even agree with Gore. I believe that everyday Americans
are forced into denial, by the media. Television, radio, movies, and even
newspapers are all facets of media which distract us from the real issues,
especially those concerning our health and the environment. Although Al Gore
even somewhat chastised Obama for not doing anything about climate change, we
cannot forget that we the people can do something as well. Americans cannot
bestow all of our blames and problems on one person about one issue. Whether
you believe in global warming or not, in reading this article, I realized that the
facts are all there. As Gore clearly wrote, think about the heat, droughts, and
floods. Then, ask yourself and America’s referee the media “is it real?”

Killer Cats
“Cats could be Serial Killers”
September 8, 2012
Among the wild lawns of suburbia roams a new kind a
predator. One who is fast, agile, cunning and deadly. This new predator has
been known to even bring their kill to doorsteps, as if they were presenting it
as a prize to their owners. I am talking about none other than cute and lovable
domestic cats. Yes, cats. A recent study by the University of Georgia has
revealed the secret lives of outdoor cats and their daily routines. The study
has found that most cats’ routines habitually consist of killing other animals
such as birds, snakes, and other various rodents. You may ask what does this
have to do with the environment, but in actuality this issue covers a wide
range of environmental issues. Birds, which were among the most common animal
killed by cats are vital to completing our ecosystem’s food chain. Without
birds the insect population would increase significantly, which will ultimately
affect plant life and even humans. Rodent deaths might not come as much of a
shock but even the smallest victim of killer cats can create a shift in our
environment’s natural food webs and food chains. We must remember that
conservation is critical to the richness and biodiversity of our planet, so remember
to watch you cats a little more closely.

Ted Talk: Pay Attention to the Penguins
Penguins are the last animals I would expect to be good “ocean
sentinels.” Penguins carry themselves so carelessly, it seems as though they
are oblivious to almost everything around them. In this Ted Talk video, a woman
named Dee Boersma explains how penguins are good indicators of what humans are
doing to the environment. Although penguins seem unaware of their environment,
it is really humans who are oblivious to what we are doing to it. Dee Boersma
was a young woman who had never been camping or even lived alone, yet she moved
to Galapagos, and actually made a considerable impact. Her ambitious and naive move
to the Galapagos Islands should serve as a testament to what we as humans can
do to help preserve our environment. Although she uses penguins as an example
of what we’ve done to the environment, such as dumping oil, we should still be conscious
of other species and their current situations. If a species such as penguins becomes
extinct then it will throw of the natural cycle of their ecosystem. It could
result in the loss of various other species. All in all we need to save
penguins because of the conditions humans have put them in. I feel this video
has taught me that we can learn more from paying further attention to the things
that suffer from our problems than the things that are causing the problems.

Floods, Droughts, and Famine

families-face-acute-famine-in-mozambican-province-&catid=98:africa&Itemid=557
All over the world various states and countries are confronted by the sometimes difficult circumstances climate has to offer. Between these three stories numerous regions have to face very different but equally detrimental weather conditions. Whether it is in Mozambique where they are facing extreme famine or in parts of Vegas and California where they are facing excessive flooding, their situations are products of severe weather conditions. I believe these conditions are strong indicators of what we may be doing to our environment, and should remind us what our environment can do to us. As we learned in class and from the article on Kenya, the closer you are to the equator the heavier the rains might be. This may explain the torrential flooding in parts of Vegas and California. The harsh droughts in North and South Dakota also might be due to a stalled high-pressure system, which could be brought about by the sister of El Nino, El Nina. El Nino brings low-pressure systems that cause hurricanes and other violent storms to North America, while the cold water current La Nina brings drought. The differences of these currents offer a variation of disasters, such as the famine in Mozambique. These four stories have helped reinforce what I’ve already learned and taught me the possible dangers of altering our planet’s climate.

Nematodes; Not Just Seen On TV
Nematodes with Pest-Fighting Potential
August 28, 2012
Nematodes aren’t just cartoon creatures that love pineapple;
they actually have some significant benefits. The U.S. Department of
Agriculture has identified a species of nematode that can invade the brains of
Formosan subterranean termites. The Formosan termite, a nonnative species from Asia
often feed on the support beams of buildings. It annually causes around $1
billion in U.S. damages, repairs, and control cost. The nematode species does
not officially kill the termites, but takes control of their bodies. Lynn Carta
a plant pathologist with the Nematology Laboratory says that the nematode’s
benefits are not yet completely apparent, but their ability to successfully inhabit
the Formosan termite could prove to be a formidable weapon against the
termites. The nematodes might prove to be a useful prospect. Lynn Carta raises
the question of using the nematodes as vectors of insect pathogens instead of
bio-control agents, which is the usual approach. I believe that these nematodes
could be helpful in controlling and reducing the detrimental effects termites
have on U.S. buildings and infrastructures. Possibly in the future the full
potential of these nematodes can be harnessed, so that termites all over the
world will never be a problem again! This is just some wishful thinking!

h.Hunters and gatherers are roles in hierarchal societies. These hunters and gatherers obtain almost all their food from animals and plants. Their impacts are most times negative because they deplete their camp area of its resources.
i.The agricultural revolution was the gradual transformation of the traditional agricultural system that began in Great Britain in the 18th century. New farming tools and methods helped increase harvest yields, but lead to excessive farming, that ultimately created land that could no longer be used for crops or any other plants.
j.Slash and burn cultivation is an agricultural technique which involves cutting and burning forest or woodlands to create fields. Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, and then abandoned. These agricultural techniques are sustainable because it forces succession, but is only acceptable where there is a very little animal and people population, and a lot of land.
k.The industrial revolution was the rapid development of industry in Britain in the late 18th and 19th centuries, which was brought about by the introduction of machines. The environmental drawbacks were air pollution, water pollution, and depletion of natural resources.
l.The scientific method is a research technique which consists of steps to develop an experiment, and find a conclusion. This method has been applied to various environmental issues to help diminish the effects of pollution, and overall create a more sustainable environment.

Name Droppers: "A Duck's Best Friend"
Jay N "Ding" Darling
A. Jay Norwood Darling was a Pulitzer Prize winning American cartoonist, who was known for his political and conservation cartoons. He was also a very important figure in the conservation movement.
B.
•He was appointed by President Roosevelt as the First Head of US Biological Survey which was the forerunner of the US Fish and Wildlife Service.
•He founded the National Wildlife Federation in 1936, which is now the largest non-profit conservation organization in the U.S.
•He used satire to promote the issues of conservation which brought national attention to environmental concerns.
• Conceived the idea for the Federal Duck Stamp Program and drew the first stamp design( these stamps helped raise money for buying wildlife habitats)
•Darling increased the enforcement of game laws that restrict hunting of animals that are becoming extinct. In 1937 he helped pass a law putting a tax on guns and ammunition, and the money from these taxes went to wildlife conservation.
C. Jay Darling fits in the Environmental Science aspect of environment and society. Darling helped pass various laws and regulations that facilitated the conservation of numerous forms of wildlife, especially birds.

Landscaping in Urban Areas Can Help Native Birds
August 22, 2012
You would think that urban landscaping has nothing to do with helping birds because they predominately live in trees, but in reality it does. A recent study by the University of Massachusetts of residential areas and the native bird population has shown that yards imitating natural vegetation offer birds “mini refuges”. These yards provide a mini oasis which help offset the loss of biodiversity in cities. The study showed that birds that lived in the “refuges” had more available resources such as seed, shelter, and lived longer but birds that lived in a more natural habitat had more alternative food resources and had a higher death rate. The researcher’s method of observation and experimentation also allowed them to separate some of the effects of bird community composition and density of competitors, and how these factors affect foraging decisions between two different landscapes. I believe that the researchers from the University of Massachusetts carried out a thorough experiment. Their data has opened my mind to what I can do to help conserve certain species that ultimately make my world a better place by eating insects. If we all just put in a little work by making our yards a little nicer, we will be providing a better habitat for not only birds but other species as well.
Check out this "bird refugee" I made using Microsoft Paint and a picture. I know it looks more like a hobo, but you get the idea. |

3: I actually learned a lot during my first week in AP Environmental Science. I learned the difference between environmental science and environmentalism. Environmental science is the unbiased study of the environment, while environmentalism is a movement regarding concerns for environmental conservation and preservation. I also learned about an effective method to reduce the amount of paper towels we waste every year. The method created by Joe Smith is called the shake and fold method, which consist of shaking your hands twelve times and only using one paper towel to dry them off. The last thing I learned about was how to convert hectares into square feet. One hectare which is an area that is 100 meters by 100 meters is equal to 107,639ft2.
2: I would like to know more about human intervention on wildlife, and what we can do to prevent the extinction of some endangered species. I would also like to know more about alternative forms of energy, and the forms that are the most beneficial for our environment.
1: One thing I feel confident about teaching to the class is the difference between environmental science and environmentalism.
"Old Spice body wash"
- Sodium Laureth Sulfate is a detergent and surfactant found in many personal care products. It is used for its cleansing and emulsifying properties. They behave similarly to soap.
- Sodium Sulfate is the sodium salt of sulfuric acid which is mainly used for the manufacture of detergents.
- Cocamidopropyl betaine is a synthetic surfactant derived from coconut oil. It is a pale yellow liquid used as a surfactant in bath products such as shampoos and hand soaps, and in cosmetics as an emulsifying agent. It also has antiseptic properties that make it suitable for personal sanitary products.
- Sodium lauroamphoacetate is an amphoacetate used in moisturizers and other various skin care products.
- Citric Acid is a weak organic acid. It can also be used to soften water, which makes it useful in soaps and laundry detergents. It is the active ingredient in some bathroom and kitchen cleaning solutions and can even be used in shampoos.
- Polyquaternium is the international nomenclature for cosmetic ingredients that are used in the personal care industry. They are positively charged, so they neutralize the negative charges of most shampoos and help hair lie flat. Their positive charges also ionically bond them to hair and skin and some even have antimicrobial properties.
- Disodium EDTA is polyamino carboxylic acid and a colorless, water-soluble solid. It is a chelating agent that helps bind impurities, which allows the major ingredients in detergents to work effectively and consistently.
- Methylchloroisothiazolinone is a preservative with antibacterial and antifungal properties. Methylchloroisothiazolinone is found in many water based personal care products and cosmetics.
- Methylisothiazolinone is a biocide that deters harmful organisms. It is commonly used in shampoos and body care products.
- Yellow-10 is a synthetic dye.
- Green-3 is a synthetic dye.
- Water is used as a solvent.

What is a hectare?
A new renewable energy project was proposed in New England, which will produce electricity by harnessing the power of the sun. There is a 20-hectare solar energy park proposal for a farmland in Lincolnshire. The actual panels will take up just 19.5 hectares and that the land underneath will provide significant sheep grazing.
20 hectares= 2,152,782ft^2
1 hectare= 107,639ft^2

The Infamous Five
Paper
Towels- Wasting paper towels seems insignificant but when millions of them
are wasted everyday they really make a detrimental impact. If we use the “shake
and fold” method we saw in class then we can save millions of trees, and ultimately
the environment.
Thermostat-People waste entirely too much electricity using their thermostats. Most people, including me turn their thermostats up too high, or too low. If we keep our thermostats at a moderate temperature of 68 to 72 degrees, then we can save a lot of power.
Air Fresheners- Various air fresheners have been found to contain carcinogens which can cause lung cancer, and even contribute to ozone depletion. Aerosol cans are inefficient and often times over used. We can diminish the amount of carcinogens we emit by using something as simple as scented candles.
Plastic Bags- Only 5% of plastic bags are recycled. They are most times littered or spend time decomposing in landfills or on the side of the road. If we use reusable grocery bags we will be able to save the environment from sea and land pollution.
Soda Pack Rings- Soda rings strangle animals all the time. Most birds and fish get their heads stuck in a ring and are choked to death. We can simply prevent this by cutting the rings before we dispose of them, properly!

TED Talk Reflection
Wasting paper towels is on my list of shameful and casual habits
that could be improved upon, and today in class I was forced to
face the reality of my careless hand drying methods. In this short TED talk
video, a man named Joe Smith explains how to dry your hands with only one paper
towel. He gives a demo which consists of two crucial steps: shake your hands
twelve times and fold the paper towel in half. This method may seem simple but
if the staggering numbers he gave are true, then we can all risk looking a
little silly shaking our hands twelve times. I believe Mr. Smith’s method of conserving paper towels
is thorough and effective. Everyday people waste millions of paper towels, and
I’m even a habitual offender. Most people don’t realize that their profligate disposal
of paper towels affects the environment in numerous ways. Thousands of trees are
sacrificed for the production of paper towels, the plastic they are packed in
harms the environment, and the most detrimental pollution comes from the
factories that produce the paper towels themselves. Joe Smith’s technique is effortless
and efficient, you wash, shake, fold, and your dry! His method is not only
working towards preservation for a better environment and future, but it is fun
as well. So the next time you wash your hands don’t forget to shake and fold!

Environmental Autobiography
When I was younger the backyard creek was our
everyday play place and a new world in itself. It was in this place where, my
brother, friends and I created imaginary and whimsical worlds in which we
relished in the creek’s natural beauty and wildlife. The creek epitomized
everything that I loved, it had an abundance of animals, the water was
pristine, and its solitary location allowed the sounds of nature to resonate
through the air. We often journeyed down to the creek to explore its streams
and catch craw fish, newts, tadpoles, and minnows, but, this all ended a few
years ago. The once intriguing and vibrant creek became murky and polluted. The
animals that called this creek home were now scarce and trash was scattered
across the water’s banks. As the years progressed the beauty of the creek
slowly diminished, and even now it is nothing more than a muddy and shallow
stream of water, that no longer flows vigorously, but trickles lazily. I love
the creek and, it is and will always be a vital location in my life. Exploring
the creek and the nature that it harbors has fostered my great love for
animals. The diverse wildlife ignited the passion I have for all creatures,
especially reptiles, so the dilapidation of this iconic location has made me
realize what we are doing to our planet, and maybe even what I can do to help. I
guess it is true what they say, “you don’t know what you have until it’s gone.”
