Available in PDF, EPUB and Kindle. Book excerpt: Orcinus Orca is the world's largest predator, and simultaneously a significant tourist asset and cultural icon for much of the Pacific Northwest. In the past two decades, the Southern Resident Killer whale (SRKW) population has declined by more than 25 percent, putting them at risk of extinction. The cause of this decline is hotly debated. This paper employs novel data, an innovative noise pollution model, and quasi-experimental methods borrowed from environmental economics to solve this puzzle. We find consistent evidence that vessel noise pollution from international shipping has lowered fertility and raised the mortality of the SRKW significantly. Had noise pollution remained at its pre-1998 levels, the SRKW population would be 30% larger. Noise pollution is a growing threat to marine mammals worldwide.

Book excerpt: Orcinus Orca is the world's largest predator, and simultaneously a significant tourist asset and cultural icon for much of the Pacific Northwest. In the past two decades, the Southern Resident Killer whales (SRKW) have declined by more than 25 percent, and this population appears on a slow-motion path towards extinction. This paper combines elements from biology and economics to put forward a new methodology for investigating their collapse and presents empirical work supporting its novel explanation - the Orca Conjecture. The key mechanism is ecological - Gause's law of competitive exclusion - combined with a shock coming from booming trade with Asia. Using three different empirical methods drawn from economics, I find the attendant noise disturbance from increased ship traffic post-1998 has lowered births and raised deaths significantly, placing the SRKW on a slow-motion path towards extinction.

Download or read book Of Orcas and Men written by David Neiwert and published by Abrams. This book was released on 2015-06-16 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: A journalist “convincingly spells out the threats to their survival, their misery in captivity, and what scientists can learn by studying them” (Kirkus). The orca—otherwise known as the killer whale—is one of earth’s most intelligent animals. Remarkably sophisticated, orcas have languages and cultures and even long-term memories, and their capacity for echolocation is nothing short of a sixth sense. They are also benign and gentle, which makes the story of the captive-orca industry—and the endangerment of their population in Puget Sound—that much more damning. In Of Orcas and Men, a marvelously compelling mix of cultural history, environmental reporting, and scientific research, David Neiwert explores an extraordinary species and its occasionally fraught relationship with human beings. Beginning with their role in myth and contemporary culture, Neiwert shows how killer whales came to capture our imaginations, and brings to life the often catastrophic environmental consequences of that appeal. In the tradition of Barry Lopez’s classic Of Wolves and Men, David Neiwert’s book is a triumph of reporting, observation, and research, and a powerful tribute to one of the animal kingdom’s most remarkable members. Praise for Of Orcas and Men “Human beings need to learn from and understand the cooperative nature of orca society. Everyone who is interested in both animal and human behavior should read this remarkable book.” —Temple Grandin, New York Times–bestselling author of Animals in Translation and Animals Make Us Human “Powerful and beautifully written.” —Jane Goodall “Humans and killer whales have a long and complicated history, one that David Neiwert describes forcefully and eloquently in this fascinating and highly readable book.” —David Kirby, New York Times–bestselling author of Death at SeaWorld “[A] breathtaking survey of orca science, folklore, and mystery.” —The Stranger

Available in PDF, EPUB and Kindle. Book excerpt: Nowhere has the divide between advocates and critics of globalization been more striking than in debates over free trade and the environment. And yet the literature on the subject is high on rhetoric and low on results. This book is the first to systematically investigate the subject using both economic theory and empirical analysis. Brian Copeland and Scott Taylor establish a powerful theoretical framework for examining the impact of international trade on local pollution levels, and use it to offer a uniquely integrated treatment of the links between economic growth, liberalized trade, and the environment. The results will surprise many. The authors set out the two leading theories linking international trade to environmental outcomes, develop the empirical implications, and examine their validity using data on measured sulfur dioxide concentrations from over 100 cities worldwide during the period from 1971 to 1986. The empirical results are provocative. For an average country in the sample, free trade is good for the environment. There is little evidence that developing countries will specialize in pollution-intensive products with further trade. In fact, the results suggest just the opposite: free trade will shift pollution-intensive goods production from poor countries with lax regulation to rich countries with tight regulation, thereby lowering world pollution. The results also suggest that pollution declines amid economic growth fueled by economy-wide technological progress but rises when growth is fueled by capital accumulation alone. Lucidly argued and authoritatively written, this book will provide students and researchers of international trade and environmental economics a more reliable way of thinking about this contentious issue, and the methodological tools with which to do so.

Download or read book Orca written by Jason M. Colby and published by Oxford University Press. This book was released on 2018-05-01 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the release of the documentary Blackfish in 2013, millions around the world have focused on the plight of the orca, the most profitable and controversial display animal in history. Yet, until now, no historical account has explained how we came to care about killer whales in the first place. Drawing on interviews, official records, private archives, and his own family history, Jason M. Colby tells the exhilarating and often heartbreaking story of how people came to love the ocean's greatest predator. Historically reviled as dangerous pests, killer whales were dying by the hundreds, even thousands, by the 1950s--the victims of whalers, fishermen, and even the US military. In the Pacific Northwest, fishermen shot them, scientists harpooned them, and the Canadian government mounted a machine gun to eliminate them. But that all changed in 1965, when Seattle entrepreneur Ted Griffin became the first person to swim and perform with a captive killer whale. The show proved wildly popular, and he began capturing and selling others, including Sea World's first Shamu. Over the following decade, live display transformed views of Orcinus orca. The public embraced killer whales as charismatic and friendly, while scientists enjoyed their first access to live orcas. In the Pacific Northwest, these captive encounters reshaped regional values and helped drive environmental activism, including Greenpeace's anti-whaling campaigns. Yet even as Northwesterners taught the world to love whales, they came to oppose their captivity and to fight for the freedom of a marine predator that had become a regional icon. This is the definitive history of how the feared and despised "killer" became the beloved "orca"--and what that has meant for our relationship with the ocean and its creatures.

Book excerpt: Experience the hauntingly beautiful world of orcas, and discover the stories that unfold when humans enter oceans alongside them. Winner of the National Outdoor Book Award by the NOBA Foundation, Honorable mention for the Sigurd Olson Nature Writing Awards by the Northland College When intrepid biology student Hanne Strager volunteered to be the cook on a small research vessel in Norway's Lofoten Islands, the trip inspired a decades-long journey into the lives of killer whales—and an exploration of people's complex relationships with the biggest predators on earth. The Killer Whale Journals chronicles the now internationally renowned science writer's fascinating adventures around the world, documenting Strager's personal experiences with orcas in the wild. Killer whales' incredible intelligence, long life spans, and strong family bonds lead many people to see them as kindred spirits in the sea. But not everyone feels this way—like wolves, orcas have been both beloved and vilified throughout human history. In this absorbing odyssey, Strager traces the complicated relationship between humans and killer whales, while delving into their behavior, biology, and ecology. She brings us along in her travels to the most remote corners of the world, battling the stormy Arctic seas of northern Norway with fellow biologists intent on decoding whale-song, interviewing First Nations conservationists in Vancouver, observing Inuit hunters in Greenland, and witnessing the dismantling of black market "whale jails" in the Russian wilderness of Kamchatka. Through these captivating stories, Strager introduces us to a diverse cast of characters from Inuit elders to Australian Aboriginal whalers and guides us through the world's wild waters, from fjords above the Arctic circle in Norway to the poaching-infested waters off Kamchatka. Featuring astonishing photographs from famed nature photographer and conservationist Paul Nicklen, The Killer Whale Journals reveals rare and intimate moments of connection with these fierce, brilliant predators.

Book excerpt: In November 2005, Washington's iconic killer whales, known as Southern Resident orcas, were placed on the endangered species list. It was a victory long overdue for a fragile population of fewer than one hundred whales. Author and certified marine naturalist Sandra Pollard traces the story and destinies of the many Southern Resident orcas captured for commercial purposes in or near the Puget Sound between 1964 and 1976. During this time, these highly intelligent members of the dolphin family lost nearly one-third of their population. Drawing on original archive material, this important volume outlines the history of orca captivity while also recounting the harrowing struggle--and ultimate triumph--for the Puget Sound orcas' freedom.

Book excerpt: On February 24, 2010, Tilikum, the largest killer whale at SeaWorld, suddenly dragged Dawn Brancheau, his trainer, into the pool and killed her. Journalist Tim Zimmermann set out to find out why. His riveting account of Tilikum's life, and the history of killer whale entertainment at marine parks, dives into the world of the ocean's top predator. It chronicles Tilikum's capture and separation from his family, and the physical and psychological stress he experienced in marine park pools over some 30 years. It explores Tilikum's involvement in two previous deaths. And it details the inherent risks of using captive killer whales for human entertainment. Ultimately, Zimmermann explains how the life of Tilikum came to mean the death of Dawn Brancheau.
Download or read book Beneath the Surface written by John Hargrove and published by St. Martin's Press. This book was released on 2015-03-24 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: *Now a New York Times Best Seller* Over the course of two decades, John Hargrove worked with 20 different whales on two continents and at two of SeaWorld's U.S. facilities. For Hargrove, becoming an orca trainer fulfilled a childhood dream. However, as his experience with the whales deepened, Hargrove came to doubt that their needs could ever be met in captivity. When two fellow trainers were killed by orcas in marine parks, Hargrove decided that SeaWorld's wildly popular programs were both detrimental to the whales and ultimately unsafe for trainers. After leaving SeaWorld, Hargrove became one of the stars of the controversial documentary Blackfish. The outcry over the treatment of SeaWorld's orca has now expanded beyond the outlines sketched by the award-winning documentary, with Hargrove contributing his expertise to an advocacy movement that is convincing both federal and state governments to act. In Beneath the Surface, Hargrove paints a compelling portrait of these highly intelligent and social creatures, including his favorite whales Takara and her mother Kasatka, two of the most dominant orcas in SeaWorld. And he includes vibrant descriptions of the lives of orcas in the wild, contrasting their freedom in the ocean with their lives in SeaWorld. Hargrove's journey is one that humanity has just begun to take-toward the realization that the relationship between the human and animal worlds must be radically rethought.
