Author’s Note: In lieu of my typical destination article (because oh boy we have some great ones in the works for you) I am starting a series of the Top 10, to be continued in various intervals.

1. (Don’t) Dress up for your Flight: Ok so you’re going on vacation, and it’s been who-knows-how-long since you’ve had one. I understand that this is a special occasion, and often see those travelers who have “dressed-up” for the airport. It’s a bad idea and here’s why; firstly you’re showing every pick pocket and tourist scam-artist that you are a Tourist. That translates to pure gold for them, and you will easily become a target. Secondly, no matter how short the flight is, or how luxurious your on-board accommodations are, you will look like a sorority girl who never went to sleep after homecoming by the time you walk out of your destination airport. Best to keep things simple when flying. Be chic, but don’t be high-maintenance. For the ladies, don’t wear too much makeup or you’ll end up like Tammy Faye Baker on an evangelistic tour of the swamp. Guys, stay away from heavy colognes, and double up on the deodorant.

2. (Don’t) Fly Air France, Continental or US Airways: As a travel correspondent, and many days on the road as a model in my hey-day, I learned which airlines were the most convenient, customer-focused, and responsive to complaints or a lack of service. The three afore-mentioned do neither. Air France actually doesn’t have ANY way for a customer to call in and make complaints or suggestions. Continental has literally lied to me and hundreds of others to save themselves hotel fees, claiming weather as a factor in the delay of 6 flights. Most of the passengers missed the connecting flights, and in reality it was a downed control tower that caused the problem. US Airways has consistently the worst attitude amongst its attendants.

3. (Don’t) Drink Heavily the Night Before: Yes, this IS a hard rule to keep! Often there is the urge to begin the vacation the night before, but this will only leave you dehydrated and with a headache that the plane’s pressurized compartments will only exaggerate.

4. (Don’t) Eat Airplane Food: Ok, I admit it: Lufthansa food was amazing “" but they’re the exception. This rule also is extremely dependent upon whether you fly economy or First Class, of course, but this is a fairly easy thing to avoid, or at least diminish greatly. The day of the flight, bring along a salad, raw veggies, a sandwich, etc. Just make sure there are no pure liquid contents, and buy a reusable 3 oz dispenser for things like dressing and condiments. Fresh fruit is a great way to maintain your hydration levels when flying. If you are flying to a foreign location, pack snacks that remind you of home. Sometimes foreign fare can be a bit tricky, but with a grab bag of cookies, crackers and pretzels, you’re sure to stay satisfied.

5. (Don’t) Arrive to the Airport Late: It’s a terrible idea! Pack the night before. You never know the state of pandemonium at the airport. The earlier you show up for those morning flights, and for the mid to late afternoon internationals, the shorter the security lines. Sure, sitting at the gate for 2 hours is rough, but you brought snacks, right!? This is when to have a glass of wine, check those last minute emails and relax.

6. (Don’t) Be afraid to ask questions: Know your rights. Each and every airport has a list of various passenger rights, and you should do your homework. As mentioned above in Item two, airlines will do anything they can think of to save money and put themselves first. Don’t assume that they are looking out for you. Ask questions, lots of them if necessary, about what the delay is, or what they’re going to do in the event of an unforeseen complication. Airlines are the first major corporations to assume responsibility for their rights as a company, and they have the right to make the rules up as they go along. Be informed, be assertive and don’t let them bully you!

7. (Don’t) Board the plane empty handed: Take whatever you need to stay occupied and satisfied. It’s no secret that I travel with my teddy bear. Sure I get funny looks at my age whipping out an old ratty teddy bear, but so what! When you are away from home a lot, it’s nice to have a piece of it with you. If you’re going on an extended vacation, take photographs, pillows – anything that will make you feel at home and at peace. Take a few magazines, a book to read, crossword puzzles, emails, etc to keep you occupied on the plane and make the whole ordeal go by a bit quicker. If you’re distracted, you won’t be inclined to worry about the physics of thrusting a mega-ton piece of metal in the air.

8. (Don’t) Forget to pack any necessities in your carry on: Hopefully, your luggage will get off the plane when you do, but there is the chance that it won’t. If there are any medications you need, take them on the plane with you. The same goes for a toothbrush, deodorant and anything you think you may need should you be without your luggage for a day or two (sexy heels perhaps?).

9. (Don’t) Get in the way: This goes for other passengers, attendants and security officials. If you are on a moving walkway, please stand right and walk left. Often, moving walkways are used when the distance between gates is farther than usual and those of us with layovers do not want to run you over trying to make a mile in six minutes. Be aware of other people’s personal space, and avoid using the chair in front of you to catapult yourself out of your seat. Whiplash is bad. Don’t be fearful of using your fair share of space, but don’t be a space-hog. If you need to check your phone or grab your boarding pass, stand to the side.

10. (Don’t) Be a Negative Nelly: Everyone is annoyed by the airlines, the security lines, the bad food, the recycled air. There is no need to take that out on your fellow passengers or the flight attendants. I don’t know how many times I’ve had some random guy scream at me to move up in the line a whole four feet, when there was still 20 people in front of us to screen…DON’T be that guy. And if you hear a hearty laugh across an airport terminal one day, it is probably me, laughing at “That Guy.”

Dear EarthTalk: What are “eco-villages?” I’ve heard of one in New York near Ithaca and another one called Arcosanti being built in Arizona.‚ ‚ ‚ – Jim Killian, Brookline, MA‚ ‚ 

Eco-villages are essentially designed communities intending to be socially, economically and ecologically sustainable. Environmentalist Joan Bokaer developed the vision for the first eco-village, which would eventually be built on the outskirts of Ithaca, New York, while on a continent-wide walk for sustainability across the United States in 1990. In Context magazine publisher Robert Gilman helped refine the concept through his research, writing and speaking on the topic. In 1996, the first residents moved into the EcoVillage at Ithaca, and a movement was born. According to the nonprofit Global Ecovillage Network, some 420 eco-villages exist in both urban and rural settings around the world today.‚ 

The defining characteristics of an eco-village, according to Robert Gilman’s seminal 1991 article, “The Eco-Village Challenge,” include “human-scale, healthy and sustainable development, full-featured settlement, and the harmless integration of human activities into the natural world.” Gilman also said that eco-villages should limit their populations to 150 individuals, which is the maximum size for any working social network according to the teachings of sociology and anthropology.‚ 

While the term eco-village did not come into common usage until the 1990s, the concept may in fact be older. Arcosanti, a self-described “experimental town” in the high desert of Arizona, 70 miles north of Phoenix, has been under construction since 1970 and eventually will be the home of some 5,000 forward-thinking residents. In keeping with the concept of clustered development so as to maximize open space and the efficient use of resources, the large, compact structures and large-scale solar greenhouses of Arcosanti occupy a small footprint-only 25 acres-within the community’s 4,000-acre “land preserve.”‚ 

Italian architect Paolo Soleri designed Arcosanti according to his concept of “arcology” (architecture + ecology), whereby, in his words, “the built and the living interact as organs would in a highly evolved being.” Underpinning the concept is that “many systems work together, with efficient circulation of people and resources, multi-use buildings, and solar orientation for lighting, heating and cooling.”‚ 

Those interested in learning more can attend a four-week workshop at Arcosanti to study building techniques and arcological philosophy, while getting a chance to contribute to the city’s ongoing construction. To date, some 5,000 participants have all had a hand in the construction of Arcosanti.‚ 

Some other “intentional communities” designed with sustainability in mind around North America include Cobb Hill in Vermont, Vegan in Hawaii, Dancing Rabbit in Missouri, Maitreya in Oregon, Dreamtime in Wisconsin, Paz in Texas, Earthaven in North Carolina, Prairie’s Edge in Manitoba and Kakwa in British Columbia. For information on these and other eco-villages, the Ecovillage Network of the Americas as well as the Global Ecovillage Network offer extensive resources for free online.‚

Dear EarthTalk: How can I determine if it is more eco-friendly to fly or drive somewhere?‚ – Christine Matthews, Washington, DC‚ 

The simple answer is that driving in a relatively fuel efficient car (25-30 miles per gallon) usually generates fewer greenhouse gas emissions than flying. In assessing the global warming impact of a trip from Philadelphia to Boston (about 300 miles), the environmental news website Grist.org calculates that driving would generate about 104 kilograms of carbon dioxide (CO2)-the leading greenhouse gas-per typical medium-sized car, regardless of the number of passengers, while flying on a commercial jet would produce some 184 kilograms of CO2 per passenger.‚ 

What this also means, of course, is that while even driving alone would be slightly better from the standpoint of greenhouse gas emissions, carpooling really makes environmental sense. Four people sharing a car would collectively be responsible for emitting only 104 kilograms of CO2, while the same four people taking up four seats on a plane would generate some 736 kilograms. ‚ 

Journalist Pablo Pƒ¤ster of Salon.com extends the comparison further to a cross country trip, and comes to similar conclusions. (Differences in the math are attributable to the use of slightly varying assumptions regarding fuel usage and source equations.) Flying from San Francisco to Boston, for example, would generate some 1,300 kilograms of greenhouse gases per passenger each way, while driving would account for only 930 kilograms per vehicle. So again sharing the drive with one or more people would lower each individual’s carbon footprint from the experience accordingly.‚ 

But just because driving might be greener than flying doesn’t mean it always makes the most sense. With current high gas prices, it would cost far more in fuel to drive clear across the United States in a car than to fly non-stop coast-to-coast. And that’s not even factoring in the time spent on restaurants and hotels along the way. Those interested in figuring out driving fuel costs can consult AAA’s nifty online Fuel Cost Calculator, where you can enter your starting city and destination as well as the year, make and model of your car to get an accurate estimate of what filling “Ëœer up will cost between points A and B.‚ 

Once you’ve made your decision whether to drive or fly, consider purchasing carbon offsets to balance out the emissions you are generating with cash for renewable energy development. TerraPass, among others, makes it easy to calculate your carbon footprint based on how much you drive and fly (as well as home energy consumption), and then will sell you offsets accordingly. (Monies generated through carbon offsets fund alternative energy and other projects, such as wind farms, that will ultimately take a bite out of or eliminate greenhouse gas emissions). ‚ 

Of course, an individual’s emissions from riding a bus (the ultimate carpool) or a train (many of which rely solely on electric power generated by their own motion) would be significantly lower. Paster adds that a cross-country train trip would generate about half the greenhouse gas emissions of driving a car. The only way to travel greener might be to bicycle or walk-but the trip is long enough as it is.‚
