Most people who know their way around their kitchen will be familiar with the “click, click, whoosh” sound of gas burners igniting. Even those who aren’t will have likely watched a cooking show on TV and seen chefs adjusting the flames under their pans to get just the right level of heat. Thanks partly to industry marketing, gas has long been seen as the cook’s fuel of choice.

Now, though, that reputation is sputtering. Natural gas use contributes to climate change – and as Boston University environmental health scholar Jonathan Levy explains, it also generates indoor air pollutants that can worsen asthma and other lung ailments. You may not need a new stove, but make sure your kitchen is well ventilated, even if that just means opening windows.
