The following guest blog from journalist and ocean activist David Helvarg is an excerpt from his latest book, “Saved by the Sea - A Love Story with Fish”
Recently I flew from California to Washington to ride on one of the Coast Guard's big icebreakers heading north. As I looked down at the snowcapped northern California mountain ranges they reminded me of great white-capped ocean waves.
Actually they're not unlike waves in geological terms, bridging up across the landscape, surfing the magma where the Pacific and North American tectonic plates collide and subside beneath them. Mountains are the rippling breakers of the planet, though functioning in a timeframe that make our species seem as transitory as mayflies or molecules. Only evolutionarily hardened marine life such as horseshoe crabs and Nautilus have been around long enough to see mountain ranges rise up and erode away again.
