Southeast of San Francisco, on the way out to California's Central Valley, thousands of wind turbines dot the landscape of Altamont Pass. Mounted both in rows and individually, machines with large propellers catch the wind, turning round and round at different speeds. Learn how wind energy is generated and stored for use in this most peculiar area, and its impact on living things both near and far.

Twenty-seven miles beyond the Golden Gate, the craggy Farallon Islands have been home to fur-seal hunters from Russia, a gold-rush-era egg business, and even a nuclear waste dump.

Dr. Bart Kempenaers, a behavioral ecologist from the Max Planck Institiute of Ornithology in Seewiesen, Germany, and his team fashion fake Sandpiper eggs, swap them for the real ones in the nest and incubate them in their lab at BASC’s (Barrow Arctic Science Consortium) new research facility. Once the hatchlings emerge, they take samples from them to determine factors such as paternity. The chicks are then returned to the nest, without the mother batting a feather.
