Greenhouse Gases From Anesthesia | Fighting Militarization In The Mariana Islands

Emissions from anesthesia are one of the largest sources of greenhouse gases from hospitals. This anesthesiologist wants to change that. And, a cultural anthropologist discusses the Mariana Islands’ long history of colonization and why demilitarization matters for climate progress.A Major Source Of Greenhouse Gases In Hospitals? AnesthesiaDid you know that some of the gases used in anesthesia are strong greenhouse gases? A few years ago, Seattle Children’s Hospital analyzed its carbon footprint and found that the gases used in anesthesia made up about 7% of the hospital’s total emissions, right behind emissions from heating and power and those from commuting.Faced with this problem, Dr. Elizabeth Hansen, a pediatric anesthesiologist at Seattle Children’s, took matters into her own hands and slashed the operating room’s emissions. She now helps other hospitals do the same with Project Spruce.Guest host Anna Rothschild talks with Dr. Hansen about how and why she took on the problem.Militarization And Environmental Injustice In The Mariana IslandsLet’s take a trip to the Northern Mariana Islands, a string of islands in the Pacific just north of Guam. The islands were sites of major battles during World War II and were captured by the United States in 1944. The US established a military presence across the territory—including building the world’s largest air force base at the time, on an island called Tinian.The US military never left, and in the 1980s, the Northern Mariana Islands became a US territory. A few years ago, the Pentagon proposed building a bombing range on an island called Pagan, but residents of the islands pushed back.Dr. Isa Arriola is a cultural anthropologist at Concordia University in Montreal and co-founder of the organization Our Common Wealth 670, based in Saipan, the capital of the Northern Mariana Islands. She’s fought back against the militarization of her home islands, and she talks with guest host Anna Rothschild about how the military presence has affected the people and environment of the Marianas, and why demilitarization needs to be part of climate action.Transcripts for each segment will be available after the show airs on sciencefriday.com.
