The Omega Principle

Más información sobre el libro

Omega-3 fatty acids have long been celebrated as key to a healthy heart and a sharper brain; today they are a multi-billion dollar business, even as recent medical studies urge caution. Greenberg shows that this is only the latest product of the reduction industry, a vast, global endeavor that over the last century has boiled down trillions of pounds of marine life into animal feed, fertilizer, margarine, and dietary supplements. The creatures that are the victims of that industry seem insignificant, but turn out to be essential to the survival of sealife of all kinds. Greenberg probes the push-and-pull of science and business; the fate of our oceans in a human-dominated age; and the human quest for health and long life at all costs.-- adapted from publisher info
