Talking of biospheres:

“How will we live together?” – Sidmouth Solarpunk

How about this in Montreal:

The  Montreal Biosphere  is a museum dedicated to the environment in Montreal, Quebec, Canada. It is housed in the former United States pavilion constructed for Expo 67 located within the grounds of Parc Jean-Drapeau on Saint Helen’s Island. The museum’s geodesic dome was designed by Buckminster Fuller.

With news just in:

It changed its name to The Biosphere, Environmental Museum in 2007 and now serves as the only museum in North America dedicated to the environment.

Following “long and arduous negotiations and several years of uncertainty,” Ottawa, Quebec and Montreal announced Monday that they will each contribute $15 million over the next five years to help relaunch the museum’s activities.

The building is currently closed because of the pandemic, but it very much seems that Mr. Fuller’s dome is back in fashion–at least for the next five years.
