Excerpt from this story from Mother Jones:

Across the globe, human activities are changing the way our planet smells. In Egypt, increasing temperatures are shrinking yields of aromatic jasmine flowers; in France, extreme drought has reduced the production of fragrant, night-blooming tuberose, a major ingredient in many perfumes; in Italy, climatic extremes are altering the characteristic floral, citrusy scent of bergamot. 

But anthropogenic factors are also reshaping environmental smellscapes, a word coined in the 1980s to describe the totality of scents in a given geographic area, in ways that are far more subtle—and potentially much more harmful.

While humans largely rely on sight and sound in our interactions with each other and with the world around us, many other creatures rely on smells. Ants, for example, require scents for colony cohesion; turkey vultures let scent guide them to far-away carrion; and male moths use scent to find females hundreds of meters away. “Scent is very important because it mediates so many interactions within an ecosystem,” says James Blande, a chemical ecologist at the University of Eastern Finland. 

These scent-based interactions are crucial for the maintenance of ecosystem services that directly benefit humans, from the bees and moths that pollinate crops to the flies and dung beetles that recycle the nutrients from dead and decomposing matter. Intact channels of scent communication are likely also important for the preservation of biodiversity. For example, many rare orchid species use scent to attract the co-evolved pollinators they need in order to reproduce, and scent helps guide monarch butterflies to the single type of plant on which they lay their eggs.

But just as we are discovering how important these chemical communication channels are to the fabric of the natural world—and the many benefits we reap from it—we are also learning how drastically they can be disrupted by our activities, including climate change and air pollution.
