Discussion Question 8
To be honest the Friends of Science website caught me off guard. I thought it was a prevention of climate change website at first because of the revolving earth logo and the "scientific" layout and design of the website. When I started reading though I realized ...not so much. They took a very scientific approach to disproving that humans are causing climate change. It would be hard to argue their points unless you were a scientist or did you own research and read their sources. Most people though are not too familiar with climate change and if this was the first time I was being presented with scientific information on climate change I would probably by into it. I noticed there were very few link references but if you do go further into the website you can download an annotated bibliography. The annotated bibliography is from a book (which you can also download), which purpose is like the website's to disprove climate change. The sources looked pretty legitimate to me but I'm not a scientist. Also the question comes to mind... Are they misquoting the data for their own agenda?
They'll Find Any Point to Argue
The Grist article brought me back to my days of high school chemistry. My teacher was probably one of the biggest climate change skeptics I have ever met. Now, this doesn't come as a surprise to me, seeing as I live in a tiny town full of Republicans. But as one of the oldest (as in, he taught my mom chemistry too) and most respected teachers at the school, most people would just believe anything that he said. One of the most distinct "climate change skeptic" viewpoints that I remember him sharing is about the "fabricated" hole in the ozone layer. His justification was that ozone is a molecule, and thus it cannot create a layer, much less a hole, because the molecules are always moving around in the atmosphere. Since everyone respected him as a teacher, no one really refuted his points, knowing that he was very set in his ways. Everyone just took what he had to be true.
What I don't understand, then, brings us back to the Grist article. In today's world, there are so many indicators and scientific proof that climate change is happening. And it is happening at such a fast pace that it cannot possibly just be a natural phenomenon. I think there were some funny ideas brought up, but it all came back to basically the same idea that no matter how hard you try, most skeptics will not listen to you. They will always bring up the same justifications for the fabrication of climate change, like Democrats wanting more tax money and wanting to kill capitalism and the American way of life. What they don't realize is that with a bit of work, we can change the basics of the system to make it better for the environment, without reverting back 300 years to 1709. Maybe one day, with enough persuasion, all of the skeptics will finally see the light and realize that they are incorrect. Until then, all we can do is hope for this turning point and make sure that we don't lose any support to them.

Real Science?
The 'Friends of Science' website is one of the more compelling cases I have seen. Usually, skeptics are satisfied merely claiming that there is no evidence or consensus and that its all a liberal conspiracy. This site, however, addressed individual scientific claims and refuted them. Nonetheless, I found most of the arguments to be trivial points that were exaggerated to seem crucial. For example, a main point made was the importance of CO2 in the greenhouse gas effect. They argued that water vapor and other gases constitute a larger percentage of the effect itself. However, this point is irrelevant when you incorporate data that show human induced CO2 emissions compared to human induced increases in other GHGs. Just because CO2 is a small part of the atmospheric composition, does not mean anthropogenic increases of its presence in the atmosphere cant affect the greenhouse effect.
Although I am certainly biased, I definitely found the grist piece more convincing. The arguments presented were more detailed and provided a clearer picture of the situation, rather than an attack on the other side's position. I also appreciated the long lists of supporters in the international scientific community for each argument. This is not to say, however, that the Friends of Science site was poorly done. I think it is very well done, and is probably very successful in providing evidence to those who agree with it. I just dont believe that it was scientifically successful enough to make people change their minds
I personally try to ignore the debate over climate change science. I find the arguments to be largely irrelevant and unnecessary; they seem like pure distractions. I think there are plenty of good reasons to stop burning fossil fuels and revamp our energy policy, and there are more than enough reasons to fundamentally change our consumptive habits. If people cant agree about the scientific basis of global warming, they can at least agree that oil will eventually run out, and that our impact on the planet is exceeding its limit in many other ways. If we dont put down our partisan fighting on these issues, we are going to find out who is right and wrong the hard way

Biodiversity
Not everyone will agree with me on this but I would say yes. We should concern ourselves with "saving nature" considering we're the ones that are wiping them out. We rely on nature. The End of the Wild made a good point when it talked about how wetlands kind of act as a natural barrier to hurricanes. When we destroy these or build on them, we are putting ourselves in danger. I think we can learn a lot from different species and it would be unfair if we only focused on industrializing and take nature for granted.
The End of the Wild
As great as all of these things are, however, I am not sure that saving random species of plants and animals should be our most important concern. Obviously everything in the environment is connected and you can't simply consider on thing and completely forget about the rest. I am simply saying that some of the examples that Meyer used in his book seemed almost pointless to try to save. He wrote about one species of grass that is only in one county in California. Has this grass proven to be of any sort of benefit to the area or to humans? He didn't specifically say so. In my opinion, then, we should not focus our time, energy, and (arguably most importantly) money, on saving this one tiny species of grass. I don't agree with the vast destruction of yet untouched areas. I think that we should try to keep what we have and try to make it better and to use our time and energy preserving what isn't destined to disappear within the next few years. Nature is important and everyone, today and in the future, should get to enjoy it. Without creating some form of regulation, the natural world will certainly fall into even more of a decline than is already present.

Feeling Wild
Meyers made a very compelling case for the ineffectiveness of wildlife preserves. His theory reminds me of the phrase we refer to often in this class, that 'the earth is one, but the world is not'. We have created false wildernesses under the assumption that within their borders, they can survive perfectly without any interference from the outside world. Globalization and climate change are drastically increasing the effects of human activity on the remote parts of the world, and it is pholly of us to believe that drawing imaginary borders around certain forests will protect them from our ever reaching hand.
I want desperately to believe that we can change our ways and reverse our damage to the natural environment and biological diversity. However, I think we are indeed too little, too late. Our presence exists everywhere, and no one seems to care enough to change that. In my opinion, the way out of this path is to begin challenging the widely held idea that humans are a superior force on earth. Organized religion and cultural beliefs that are deeply entrenched in our values systems have led us to believe that we have a right as so-called 'sentient beings' to take advantage of the earth's systems and behave in the way that we please. If we ever hope to return to natural selection, instead of human selection, we have to understand that our place in the global ecosytem is no more valuable than that of an ant or a fern. Ignoring the planet's immense species diversity in the name of superiority is a downright criminal act. We should act now to reverse this ideology, and begin promoting the wilderness around us.

Eco-Tourism
Another issue, as mentioned in the question, is the air travel in order to get to these exotic locations. In today's super globalized world, everyone wants his or her chance to see it all. With relatively cheap airfare, this has become possible and has encouraged fast trips via the air to places that are not even that far away. I did a little more research on this to see what the environmental harm would actually work out to be. According to Boeing, a 747 burns approximately 5 gallons of fuel per mile. This sounds like a huge amount, except that there are a lot of people on the plane. With an average of around 500 people, the entire flight works out to about 100 miles per gallon per person. So overall, it works out to being about the same (per mile) as a family of four taking a trip in an average fuel burning car. (http://www.howstuffworks.com/question192.htm). Obviously not a good thing, but maybe not as bad as we had originally thought.
My final point is one in full support of the eco-tourism industry. By traveling, people are exposed to the issues that those in other countries face on a day to day basis. Although you may only be right in the touristy areas of another country, you are usually hard pressed to not notice some amount of environmental and social hardship around you. By taking tours of wildlife preserves and seeing nature in action, people may be affected by what they have seen and be more likely to act on it. I think that going on these tours and even simply advertising about them really helps to get the word out to the general public about all of the issues surrounding other areas of the world. Overall, I think that eco-tourism is a good thing, even if getting there and staying there may have small environmental impacts. It is a way for people to learn about cultures and issues in other parts of the world and hopefully will generate a response towards helping others throughout the earth.

Eco-Tourism
I love traveling and next semester I hope to study eco-tourism in Australia and just how feasible it is. Is it really good for the environment to travel half way across the world? How close can you interact with endangered animals without disturbing their natural habitat? Does eco-tourism boosts struggling economies? Does it protect forests that would have otherwise been torn down, if they hadn't attracted so many tourists? All of these questions I find really interesting. Part of the reason is probably because I want to justify my own desires to travel and not having to feel guilty.
I read something freshman year about how endangered species who were before being hunted were now being left alone because the local economy had been benefiting from the tourists who were coming to see them. I know it can be that simple though. However, I think it is a better way to preserve the environment than telling developing nations what they can and can not do with their resources, when Western countries have been destroying their own environments for centuries.

Living like a Tourist
As for the air travel, I find this issue to be much more difficult. I fully appreciate the devastating toll that jet airplanes have on the environment, and it seems completely ludicrous that they remain so popular and prevalent. However, I fly 2-3 times per year, because of where my home is in relation to my school, and whenever I travel abroad I obviously have to fly as well. I would not be able to live the way I do without air travel, plain and simple. Therefore, it is much harder to compromise on this issue. In addition, our global economy relies on the ability of multinational businessmen to travel all over the world every week. I cant honestly think of a solution to this problem. I can only hope that (using a more market liberal approach) we come up with more efficient aviation technologies in the future. Perhaps we can begin to limit our use of planes to overseas trips, and rely more heavily on fixed rail transit within land masses. The incredible train network in Europe can be duplicated elsewhere, and perhaps decrease our collective carbon footprint when we travel.

I Love Food.... and Farmers Markets
Last summer while working at a church camp, I decided to become a vegetarian. It was something I had wanted to do for quite some time and had even tried once before, with not much success. This time, however, I was ready to work at it. The camp's theme for the summer was about being good stewards of creation, and although the curriculum didn't teach me about living meat free, some of the other members of the staff did. Throughout the summer and ever since, I have become even more passionate about living meat-free and learning about all of the environmental and health benefits of vegetarianism.
This summer, I stayed here in DC to work. I got in the habit of taking a weekly trip to a farmers market after seeing the wide variety of locally grown food that I could get right in my own neighborhood. Occasionally I would venture down to Eastern Market with their many various vendors, but most of the time I would stick around the Bethesda area where I was living. Although not all of my food came from farmers markets, I tried to at least stock up on all my fresh fruits and veggies for the week on each weekend. I knew that even though it may not have been a huge step, it was still cutting down on the environmental impact from all of the processed foods that most Americans eat, as well as cutting down on transportation pollution from foods that must be shipped from far away.
Now that school is back in session and fall is settling in, however, it is much more difficult to eat environmentally sustainable foods. I often only have a few minutes to grab food before running to another class or another meeting. It is much easier to grab a packaged, processed meal than it is to cook something from fresh ingredients. Finances also are brought back to the forefront of my considerations now that classes are back in session. Over the summer, I was working in a paid office position, so I was able to buy fresher food, which was also usually more expensive. Now, I am an unpaid intern in the non-profit work in addition to taking classes. Since I'm simply living off my savings from the summer, I need to make choices that are the best for my wallet before really considering the environmental impact.
The worst food that I have eaten in the past few days was probably my lunch at my internship yesterday. To avoid paying nearly $10 for lunch at one of the grab and go type of places near my office, I decided to walk the 5 blocks to Safeway to grab something cheaper. I left with a $4 lunch of a salad and a microwavable 3 Cheese Ziti Marinara meal. While the salad was probably environmentally better, there were still probably many pesticides used in the production of all of the toppings I added as well as the production costs to get it to Arlington, VA. The microwavable meal was by far the worst. In order to make the nice plastic wrapped package I popped in the microwave, the wheat had to be grown and processed into pasta, the tomatoes and other ingredients made into sauce, and the cows grown and milked for the cheese. All of these production factors come from various places across the country and then are sent to one factory to make the package I purchased. When counting in all of the processing and the transportation between each step of the production, the environmental impact significantly increases.

My Favorite Subject: Food
I kind of use being a vegetarian as a free pass. My logic is since I'm already vegetarian I shouldn't kill myself over not eating enough locally grown organic foods. I do shop at Whole Foods and buy organic when I can. However my friend brought up to me that a lot of Whole Foods' foods are imported from other countries as well so I don't think I'm doing much good by shopping there.
Food for Thought
A National Eating Disorder
Because of this social phenomenon, I admit that my mind rarely takes environmental costs into account when purchasing food. True, I enjoy the satisfaction of a food labelled 'organic', and I take great pride in myself when I make the time to cook my own food, but all too often these are outweighed by my cost decisions. One thing I am conscious of is my consumption of beverages. I do my best to never purchase bottled water unless I have to, and rely instead on drinking fountains or bottles I bring from home. I have been conditioned well in the last few years to understand the mind boggling consumption and immediate disposal of plastic bottles, and it has definitely affected the way that I look at the refrigerator section of the cafe or grocery store.
In the past couple of days, I have purchased a variety of prepackaged goods. Potato chips, cans of soda, and a variety of other foods have been in my diet this week. I believe these types of goods to be the most harmful, because they involve a long line of production and transportation to reach my mouth, and have little to do with sustainable, local, or organic agriculture. If Americans want to dramatically decrease the strain they put on the environment, a good place to start would be prepackaged foods.
