Book excerpt: The oceans, and the challenges they face, are so vast that it’s easy to feel powerless to protect them. 50 Ways to Save the Ocean, written by veteran environmental journalist David Helvarg, focuses on practical, easily-implemented actions everyone can take to protect and conserve this vital resource. Well-researched, personal, and sometimes whimsical, the book addresses daily choices that affect the ocean's health: what fish should and should not be eaten; how and where to vacation; storm drains and driveway run-off; protecting local water tables; proper diving, surfing, and tide pool etiquette; and supporting local marine education. Helvarg also looks at what can be done to stir the waters of seemingly daunting issues such as toxic pollutant runoff; protecting wetlands and sanctuaries; keeping oil rigs off shore; saving reef environments; and replenishing fish reserves.
