Plenty of fish in the sea? Not anymore. As wild supplies dwindle, the long hidden ties binding all life to the ocean are clearly coming into view. Can we ignore these powerful connections? What can we do to protect the ocean, ourselves and our future? Our massive demands on the ocean’s bounty impacts life far beyond the shoreline: bushmeat hunting is on the rise in Ghana while in Namibia; fishing grounds struggle to recover as putrid fumes explode from the ocean depths and poison the waters; and radical new fish farms are sprouting up from Puerto Rico to Canada. Across the globe, all life is feeling the effects of overfishing. Can we protect fish in time to safeguard the ocean, life on land and ultimately ourselves? Find out how we all can make a difference.
