The Environmental Impacts of Tourist Traffic on Mt. Everest

Mountaineers at the Hillary Step on Mount Everest.

Purpose:
   To inform people of the effects of traffic on the slopes of Everest, a mountain sacred to Tibetans and in high regard to the rest of the world, as well as a part of nature.

Discussion Questions:
  1. Are there other ways to keep Everest clean?
·        Bishop also pays Sherpas two to three dollars per 20 pounds of trash they bring back and seven dollars per oxygen bottle
·        The Nepalese government raised the fee for climbing Everest and now requires a $4,000 deposit for each expedition as well as limiting the amount of expeditions that can take place each year. But they have to be careful so as not to upset their economy
  1. How might the circumstances of Everest change people’s priorities?
    • High altitudes impair the human mind and bod
    • In the dangerous situation of mountaineering, people are focused on their own safety rather than preserving the mountain
    • The tourists will probably not revisit Everest and so see less of a need to preserve i
  2. If this is the case, should we forbid humans to climb Everest in order to preserve it? Looking at your answer, what does this say about our perceptions of Everest’s “uses?”
  3. Does our environmental ethic change when considering unique natural sites such as Everest? Should it?
Supplemental information (before discussion):
  • The Khumbu region and Katmandu city are places nearby Everest where many tourists and climbers stay.
  • Together they have room for 40,000 people, but these days up to 700,000 people have been cramming in, with 20,000-40,000 of them attempting to summit Everest and other Himalayan mountains
  • Everest has been renamed as “the tallest landfill in the world” because covering the slopes is human waste, aluminum cans, food, climbing equipment, medical equipment, plastics, glass, batteries, clothing, fuel canisters, tents, paper, oxygen cans, and even dead bodies and bloody syringes, all totaling about 1,100 pounds of trash from every expedition.
  • Much of this waste does not decompose
  • The most trash is accumulated on the Southeast Ridge because it is the most common route up the mountain
  • People have recently been throwing their trash into crevasses because the motion of the ice grinds up trash, but this does not get rid of the problem and the trash usually ends up deposited on the lower slopes of the mountain anyway
  • It takes about a month to acclimatize, so expeditions generate more trash than you might expect
  • Tourists also effect the communities of Nepal by hoarding the countries resources
  • The environmental impacts and decreased welfare of locals outweighs the positive economical impacts of tourism in Nepal
  • An important figure in the preservation of Everest is Brent Bishop
  • He leads trips of about five people up and around the mountain, carrying back up to 5,200 pounds of waste each time.
  • 17,526 pounds is the total amount of garbage returned to the bottom of Everest so far
  • In addition to increased amounts of waste littering Mt. Everest, the traffic on the slopes causes more deaths because people have to wait for other climbers before reaching the summit.
  • Waiting for long periods is risky because of the cold temperatures, high altitude, and depleting amounts of oxygen in climber’s tanks.

Thanksgiving Turkeys

Danielle Slatkin
Date Presented:  11/26/12

Thanksgiving Turkeys


The purpose of my news report was to educate the class about the bird that they just ate on Thanksgiving.  For example, I showed the process turkeys go through to get to the slaughterhouse, as well as the effects that turkeys have on the environment and on people's health.  I displayed these facts, and showed an advertisement created by PETA, in order to let individuals in the class make an informed decision on whether or not he or she wants to continue supporting the Thanksgiving turkey industry. 

Discussion Questions:
1.     Is this an issue that Americans should care strongly about, and put as a priority?
2.     Would it be possible for Americans to break this tradition of eating turkeys? Could you give up eating turkey on thanksgiving?
3.     Is it a good tradition that the president pardons a turkey every thanksgiving?  Does this, or is this enough to promote animal rights?

Some of my Research:



·      Over 65 million turkeys are killed during the winter holiday season alone
·      The majority of these turkeys spend their entire lives confined inside massive sheds, and never set foot outside
·      In the 1960s, it took 220 days to raise a 35-pound turkey-->now, due to selective breeding and growth-promoting drugs, it only takes 132 days to raise a turkeyàfarm conditions are so harsh that the turkeys have to be pumped full of antibiotics just to stay alive
·   According to the US Dep. Of Agriculture, the single condition for the term “free-range” is that birds need to have access to the outdoorsàall other facets of a free-range turkey’s life can be indistinguishable from the living conditions of a conventionally raised bird-->turkeys, and in fact all birds, are excluded from coverage under the Humane Methods of Slaughter Act, and from the Animal Welfare Act
·      Turkey skin is also contaminated with deadly pathogens and antibiotics that are passed on to the consumers
-    much of the 10 billion pounds of manure generated by 7,300 turkey farms in 33 states ends up in our drinking water, and is responsible for the release of immense amounts of methane and nitrous oxideàthe livestock sector generates more greenhouse gas emissions than all transport combined
-     PETA used to support the turkey pardoning, but this year the PETA president Ingrid Newkird said “it makes light of the mass slaughter of some 46 million gentle, intelligent birds and portrays the United States’ president as being in some sort of business partnership with the turkey-killing Industry.  Turkeys do not need to be pardoned, they are not guilty of anything other than being born into a world of prejudice.  They are innocents who should be respected for who they are:  good mothers, smart birds, and interesting animals.”

The Rise in Cellulosic Ethanol

Macey Mathews
Presented - November  20

The Rise in Cellulosic Ethanol 

 
Purpose: 
The purpose of my presentation was to educate the class about a type of alternative fuel called cellulosic ethanol that converts wood chips and agricultural waste into fuel. Foreign dependency on oil is an ongoing issue for the US and lowering this dependence is a major priority. This fuel source can be produced within the United States and it uses products considered "waste" while also lowering the CO2 pollution. 

  1. Discussion Questions: 
    1. Ultimately do you believe that Kior and other companies will be successful in mass-producing cellulosic ethanol on a national scale?
    2. Current estimates say that this renewable oil could only supply 60% of Americans’ fuel…  what are other ideas to reduce dependence on foreign oil? 
    3. Do you believe that cellulosic ethanol will be a viable source with out  depleting natural     recourses? 

   Evidence:

  •    can affordably turn agricultural waste products into fuel.
  • ·        Kior, a company based inTexas, claimes it has produced a crude oil made from wood chips and would be expected to refine it into gasoline and diesel later this month
  • ·        Able to rearrange the molecule of the biomass into oil in a matter of moments
  • ·       Takes the cellulose, which is an energy rich molecule found in plants, and convert it into fuel
  • ·       PROCESS(for wood): Shred wood into small particles and is fed into a reactor mixing a powdered catalyst. It is then sent to the separator where the catalyst is separated from the renewable crude. The renewable crude and byproducts are then sent into the product recovery where they are cooled and separated and is condensed into a liquid and the gases are send to the cogeneration unit where they are burned and used as electricity. It is then refined into gasoline and diesel 
  • ·       Kior deals with mostly wood chips specifically the yellow pine however it is also possible to use other agricultural debris such as switch grass and corn stalk which does not compete with our food supply.
  • ·       Companies have predicted that it would reduce gas prices to around 2 dollars a gallon and would produce around 1.2 million jobs in the coming years
  • ·       Zion has recently created its first commercial fuel production facility in Columbus Massachusetts earlier this year.
  • ·       They are also currently compatible with cars on the road

Duncan Cummings News Report, 11/1/2012


The Effects of Climate Change on Hurricane Sandy

 

Purpose: Hurricane Sandy, is the super storm that was plaguing the east coast in October. The hurricane has brought storm surges, flooding and extreme winds to the New York and New Jersey areas. There are clear connections between the extreme storm conditions and the growing effects of climate change. The rising sea levels due to melting ice caps have worsened storm surges. Climate change is increasing global ocean temperatures, which increase flooding by bringing more rain. The once rare October hurricanes are now more common because of hotter temperatures. Overall, hurricane intensity has grown due to climate change, and it is yet to be determined whether or not they are increasing in numbers. The finding in this article has direct implications for future natural disasters; climate change is making them more common and possible worse.

Discussion Questions:
1. Why does North America have such a high increase in the intensity of natural disasters?
2. Could climate change be increasing the abundance of natural disasters?
3. How could climate change effect natural disasters in California?



Evidence:

"With every degree C, the water holding of the atmosphere goes up 7%, and the moisture provides fuel for the tropical storm, increases its intensity, and magnifies the rainfall by double that amount compared with normal conditions."
http://news.mongabay.com/2012/1029-hance-climate-hurricane-sandy.html

“But the sea level rise has been even more pronounced of the U.S. east coast. A study from this summer found that sea levels in the region have been rising on average 2 to 3.8 millimeters a year during the last sixty years, cumulatively, that's around 5-9 inches.”
http://news.mongabay.com/2012/1029-hance-climate-hurricane-sandy.html

“Warmer weather in the north allows hurricanes to travel further than they usually would, while hotter seasons increase the chances of October hurricanes on the eastern seaboard, once a rarity.”
http://news.mongabay.com/2012/1029-hance-climate-hurricane-sandy.html

“In fact, a 2010 review paper in Nature Geoscience found that global warming will bump up the number of particularly intense hurricanes by 2-11 percent, hurricanes just like the "Frankenstorm" Sandy.”

“Over the past half-century, temperatures and precipitation in the United States have gradually increased, more of the precipitation has fallen in heavy storms, sea level and sea surface temperatures have risen, and other aspects of climate have also changed.”

“When weather varies outside this range of tolerance, however, damages increase very disproportionately. As floodwaters rise, damages are minimal as long as the levees hold, but when levees are overtopped, damages can be catastrophic. If roofs are constructed to withstand 80 mile per hour (mph) winds, a storm bringing 70 mph winds might damage only a few shingles, but if winds rose to 100 mph, roofs might come off and entire structures be destroyed. Plants can withstand a dry spell with little loss of yield, but a prolonged drought will destroy the entire crop. The most alarming risks of damage from climate change arise from an increasing likelihood of such extreme weather events, not from a gradual change in average conditions.”



“Insured losses from disasters globally averaged $9 billion a year in the 1980s. By the 2000s, the average soared to $36 billion per year. The costliest weather disasters in the USA since 1980, as defined by insured losses, have all been hurricanes, led by Katrina in 2005 ($62 billion) and Ike in 2008 ($18 billion).”

Hazardous Waste By Sydney Block

Purpose: 

The purpose of this presentation was to inform the class about hazardous waste in the United States and and around the world. Hazardous waste disposal is an international issue that is important to be aware of and to know how to encourage safer ways to dispose these toxic materials.

Overview of Presentation:

-Hazardous wastes are byproducts of human activities
-This issue became prevalent in the 1970s when a number of high-profile human health and environmental pollution crises focused public attention on the problem
- United States industries, farms, mines, military facilities, cities, and small businesses generate roughly 200 million tons of hazardous wastes each year
-Each year, industrialized nations with strict environmental regulations export more than two million tons of hazardous waste for disposal in poorer developing nations with less stringent waste disposal oversight

Discussion Questions:

           Should there/can there be an international law limiting and regulating hazardous waste?
·      What steps do you think the US needs to take in order to decrease the amount of hazardous waste produced by American industries, farms, mines and military facilities?
·      How else can governments encourage clean and safe waste disposals?
