HARI SREENIVASAN:

That could lead to Lolita being re-acclimated over time and eventually released back into the waters off Seattle, where she was captured in 1970.

Some scientists and activists argue that the tank where Lolita currently lives alone is too small for her well-being and that she should be set free.

Lolita has been dubbed "the world's loneliest orca." And this week, hundreds marched in Miami demanding her release.

But the Miami Seaquarium says it will fight any plan to put Lolita back into the wild, arguing that she simply can't survive on her own after 45 years in captivity.

Robert Rose, the curator of the aquarium notes how hard it is for an animal that's lived in captivity for so long to be returned to the open ocean.
