Certain gases used for anesthesia are 3,000 times more damaging for the climate than CO2. Some anesthesiologists are pointing to other solutions.

This is part 1 of a three part series on a new generation of doctors leading the charge to make the health care industry more sustainable - for the benefit of their patients and the planet.

Susanne Koch, an anesthesiologist and neurologist, reached a pivot point when she was up to her neck in water, almost literally. The basement of her house in Berlin had flooded in the summer of 2018, when Berlin was pummeled by unusually strong rains. After she drained the house, “I wanted to dig into facts, to understand how exactly these extreme weather events are related to climate change,” she says.

Studying the scientific literature, she realized how urgent the climate crisis is, but the biggest shock was to learn that her profession contributed substantially to the problem: Inhalation gases used during medical procedures are among the most damaging greenhouse gases. Some inhalation gases are 3,000 times more damaging for the climate than CO2, Koch discovered. “Spending seven hours in the surgery room is the equivalent of driving a car for four days nonstop,” she says. Her job of helping people at Europe’s largest university hospital, the Charité in Berlin, was inadvertently damaging both the people and the planet.

“Nobody had ever even mentioned a word about that during my training,” Koch says.

Can tech help prevent the insect apocalypse?

Declining numbers of insects, coupled with climate change, can have devastating effects for people in more ways than one. But clever use of technologies like AI could keep them buzzing.

This article originally appeared in One Health/One Planet, a single-issue magazine that explores how climate change and other environmental shifts are making us more vulnerable to infectious diseases by land and by sea - and how scientists are working on solutions.

On a warm summer day, forests, meadows, and riverbanks should be abuzz with insects—from butterflies to beetles and bees. But bugs aren’t as abundant as they used to be, and that’s not a plus for people and the planet, scientists say. The declining numbers of insects, coupled with climate change, can have devastating effects for people in more ways than one. “Insects have been around for a very long time and can live well without humans, but humans cannot live without insects and the many services they provide to us,” says Philipp Lehmann, a researcher in the Department of Zoology at Stockholm University in Sweden. Their decline is not just bad, Lehmann adds. “It’s devastating news for humans.

”Insects and other invertebrates are the most diverse organisms on the planet. They fill most niches in terrestrial and aquatic environments and drive ecosystem functions. Many insects are also economically vital because they pollinate crops that humans depend on for food, including cereals, vegetables, fruits, and nuts. A paper published in PNAS notes that insects alone are worth more than $70 billion a year to the U.S. economy. In places where pollinators like honeybees are in decline, farmers now buy them from rearing facilities at steep prices rather than relying on “Mother Nature.”
