Photo: Theme Day -- Entry, into the Biosphere 2
The envitronment inside the Biosphere recreates different ecosystems found on earth so that the researchers can live for years within the glass enclosure, without any interaction with the outside world.
It is called Biosphere 2 because the rest of Planet Earth is Biosphere 1. Today the facility is owned by the University of Arizona and is open for tours. It is located just a little north of Tucson.
I thought that the entrance to Biosphere, which the researchers entered only once for several years, would be a fitting post for the theme of "Entry."
This week we are showing photos of Grenada, Nicaragua, on our Viva la Voyage travel photo site. It is a charming Spanish colonial city.
