The UA-operated Biosphere 2 has been named one of the “50 Must-See Natural and Man-made Marvels,” according to Life Books.

The book published by Life puts the Biosphere on the same level as other man-made objects, such as the Eiffel Tower, Golden Gate Bridge and Mount Rushmore, according to a University of Arizona news release

From the release:

Outside of Tucson, the next nearest “wonder” is the Golden Gate Bridge in San Francisco, Calif. Other U.S.-based man-made wonders include the Empire State Building in New York City, Mount Rushmore in South Dakota. The Hubble Space Telescope and the International Space Station also made the list.

Among the natural wonders that made the list are the Galápagos Islands, the Serengeti in Africa, the Rock of Gibraltar, the Amazon and the Grand Canyon. Life Books also designed 14 “original wonders” to include The Great Pyramid of Khufu, Christ the Redeemer in Rio de Janeiro and the Great Wall of China.

I’m wondering if the honor is more of an homage to Biosphere’s quirky legacy than the structure itself. While the Biosphere is an engineering marvel, I just can’t see it being in the same league as the Eiffel Tower.

Perhaps Life was intrigued by the short-lived missions that took place inside the glass structure, though my money is on subtler, more sophomoric interests.

I mean, the Eiffel Tower is amazing, but it was never the subject of a terrible, unfunny movie starring Pauly Shore and one of the 70 Baldwin Brothers, was it?

That distinction alone should separate the Biosphere from its man-made peers, if you ask me.
