How Smells Reconnect Us To Nature: Breathing Well In Urban Spaces

How Smells Reconnect Us To Nature: Breathing Well In Urban Spaces

We live in a society focused on vision. The technology, the media, the article you are reading, all of these things are mostly perceived and analyzed through our eyes. But it is to our five senses that we owe most of our daily experiences, without always always being aware of it ...

The experience of nature is a perfect example. Our relationship with the natural environment indeed responds to a complex process involving our organs from head to toe: we enjoy a forest walk on a spring morning for the bright colors and the harsh light that runs through the foliage; for the songs of birds, for the cool wind that caresses our skin.

If this moment gives us well-being, it is the fact of multiple sensory stimuli which, by mingling, define together the same experience. Thus the experience of nature is in essence a multisensory experience. But if we enjoy a walk in the forest on a spring morning, it is also for the smells that it exhales  : here the resinous perfume of a pine, there that of the humus or the hyacinths of the woods.

How Fireflies Glow -- And What Signals They're Sending

How Fireflies Glow -- And What Signals They're Sending

You might not really be sure you saw what you think you saw when the first one shows up. But you stare in the direction of the flicker of light and there it is again – the first firefly of the evening. If you are in good firefly habitat, soon there are dozens, or even hundreds, of the insects flying about, flashing their mysterious signals.

Fireflies – alternatively known as lightning bugs in much of the United States – are neither flies nor bugs. They’re soft-winged beetles, related to click beetles and others. The most dramatic aspect of their biology is that they can produce light; this ability in a living organism, called bioluminescence, is relatively rare.

I’m an entomologist who does research on, and teaches about, the ecology and biology of insects. Recently, I’ve been trying to understand the diversity and ecology of fireflies in my home state of North Carolina. Fireflies are found widely across North America, including many places in the west, but they are most abundant and diverse in the eastern half of the continent, from Florida to southern Canada.
