“In a world of seven billion people, where every inch of land has been mapped, much of it developed, and too much of it destroyed, the sea remains the final unseen, untouched, and undiscovered wilderness, the planet’s last great frontier. There are no mobile phones down there, no e-mails, no tweeting, no twerking, no car keys to lose, no terrorist threats, no birthdays to forget, no penalties for late credit card payments, and no dog shit to step in before a job interview. All the stress, noise, and distractions of life are left at the surface. The ocean is the last truly quiet place on Earth.” OceanPhysiologyOutdoorFreediving Book:Deep: Freediving, Renegade Science, and What the Ocean Tells Us About Ourselves Source: Deep: Freediving, Renegade Science, and What the Ocean Tells Us About Ourselves
