This great panel discussion happened at the CSAA, and Ellie wrote this piece: Problem Plants: Nativeness, Biodiversity, and Urban Flora in the Anthropocene.
Also, Radiolab recently produced this segment: How Do You Put a Price Tag on Nature? which was all about coming up with dollar amounts for the services of nature. As an artist-who-is-also-a-bookkeeper, I imagine balance sheets of “assets” (not sure what the liabilities would be), invoices from swamps to coastal communities for flood prevention services, and bees to Chinese apple farmers for pollination labor…
Apparently the total value of all of nature is $142.7 trillion.
There’s one problem with this, as Jad counter-argues: Nature is priceless, no? Or in deep-ecology speak, living things are intrinsically valuable, not limited to value calculated from only a narrow human perspective.
Weeds, apparently, have a negative value. Some people pay to have them removed.
At the panel, we were all talking quite a bit about various types of value that weeds have…
In one slide, Dr. Sasha Wright proclaimed, “Biodiversity is beautiful.” Aesthetic value. She also emphasized how weeds generally make an ecosystem more resilient in the face of natural disasters.
Miriam Simun told us how the Agalinis acuta flower, the only federally protected plant in NY state derives its value through scarcity, and how loads of resources are spent nurturing and protecting it.
Ellie extracts value in the form of pigments…distilling their essence in a way.
Dr. Amy Berkov told the story of how milkweed is valuable to its beetle, and visa versa.
