Leisure travel bad for the planet? Stay home?

Dear EarthTalk: Is leisure travel so bad for the planet that we are all better off just staying home?

—Jackie Smith, Boston, Massachusetts


According to the International Air Transport Association, in 2024 global air travel increased by 10.4%. Behind this surge in tourism is growing affluence in developing countries, demographic shifts to younger generations, convenience of travel, and increasing awareness through social media.

Despite the booming economies traveling creates, there lurks the harsh penalties that each flight, drive and cruise puts on Mother Earth. Tourism accounts for about 8% of world greenhouse gas emissions. University of Queensland Associate Professor Ya-Yen Sun conducted a study showing how tourism is the leading producer of greenhouse gases of all global economic sectors. Dr. Sun and his research team anticipate “annual increases in emissions of three to four percent” from travel alone.

Transportation is the primary contributor of greenhouse gases from travel, almost half of tourism’s carbon footprint. Online emissions calculator, Atmosfair, shows that a single round-trip flight from New York to Los Angeles for a typical family emits 7.1 metric tons of carbon dioxide (CO2). This is equivalent to the greenhouse gas emissions from approximately 1.7 gasoline-powered vehicles driven in one year.

“Goods” and “Food & Beverage” make up the next largest contributors of greenhouse gases. These categories encompass the souvenirs and shopping experiences of tourism, considering production, manufacturing and shipping. Food production entails growing, processing, transporting, and much more, thus multiplying its carbon footprint.

Visualizing the effects of global warming is difficult, even with these numbers and facts. Rising sea levels and dwindling ice sheets seem hardly connected to one airplane ride.

University of Tennessee Professor John Nolt concluded after calculations that “the average American is responsible, through his/her greenhouse gas emissions, for the suffering and/or deaths of one or two future people.”

Yet, we can and are doing more to combat travel’s eco-damage. Aircraft emissions are being lowered through biofuels, electric motors and efficient design. Quitting travel is extreme, but consider the impacts of your next trip. And if the answer to travel or not is yes, decrease your carbon footprint: buy offsets, choose efficient airlines, fly during the day. And remember what Dorothy concluded after her travels: “There’s no place like home.”

A life reshaped by clay in “Matin”

On Monday, Oct. 26, a group of students, teachers and local residents gathered at the Hotchkiss School in Lakeville for a screening of the new short documentary “Matin.” The film tells the story of Matin Malikzada, a seventh-generation Afghani potter making a new life in New Milford, Connecticut. The film was made by local filmmaker Yonah Sadeh, creator of the Video Wall at the David M. Hunt Library, and Berkshires-based potter Hannah Wheeler, who were both present for the screening, along with Malikzada himself.

As a member of the seventh generation of his family to master the art of pottery, Malikzada had done things the way his family had for over a century. Istalif, the village where his family has lived for generations, was known throughout Afghanistan for its pottery, with wares sent across the country for use as everyday cups, bowls, plates and other vessels. The pottery-making families of Istalif gathered clay from the same mountain, about 30 to 45 minutes away by donkey. Every July, they would head north toward the Uzbekistan border to gather ishkar, a plant they processed by hand to make their signature glazes.

L. Tomaino

When Meg Sher came to Falls Village in 2006 from Old Lyme, Connecticut, where she grew up, she never imagined she’d someday be the executive director of the David M. Hunt Library.

Although, in hindsight, perhaps it makes sense.

Crescendo’s 23rd season speaks to the heart and mind

Crescendo’s 23rd season speaks to the heart and mind

Christine Gevert, founding artistic director of Crescendo, conducts the audience at a performance.

Steve Potter

For Christine Gevert, founding artistic director of Crescendo, music from centuries past is anything but a relic. It is a living, breathing art form, full of drama, emotional complexity and, occasionally, surprises. As the regional choral and period-instrument ensemble launches its 23rd season, Gevert is once again bringing forgotten masterpieces into the present.

“Early Music has been my lifelong passion and the focus of my specialization in Europe and South America,” Gevert said. “Bringing this repertoire to our audiences in a nuanced way that does justice to its incredible depth, intensity, and beauty is deeply important to me.”

Shinbone Alley brings spooky songs to Spencertown

Shinbone Alley brings spooky songs to Spencertown

Seeing isn’t always believing. Sometimes it’s the lack of a defined picture that can be the most compelling. And when Alex Harvey of Shinbone Alley sings his supernaturally charged sea shanties and street ballads, the unseen will be downright scary. On Oct. 30, the historically inclined storyteller and performer will create a spooky evening of forbidden tales and yarns through a carefully chosen series of songs at Spencertown Academy of Arts.

The repertoire for the performance is a bit fraught. Over the years, Shinbone Alley has explored the world of folklore through music. Though the group usually features two musicians, Harvey, a multi-instrumentalist and singer, will be performing solo. That is, of course, unless you include the spirits.
