An underwater paradise in the remote Pacific Ocean that includes the sea around the southern Line Islands (Caroline Island is seen here) will be protected thanks in part to National Geographic s Pristine Seas project. Led by Explorer-in-Residence Enric Sala , the project is an ongoing effort to document and conserve what s left of the planet s least spoiled marine environments.
