Biosphere 2 ownership to pass to U of A

Posted: Updated:

TUCSON, Ariz. -- The Biosphere 2 will officially become the property of the University of Arizona on Friday.

It will be a gift from CDO ranching and development in Texas with $20 million to help support ongoing research operations from the Philecology Foundation.

More than 2.5 million people have visited the Biosphere since it was built.

By securing ownership, the U of A can now carry out long term research on the site.
