Book Description
"We fail to mandate economic sanity," writes Garrett Hardin, "because our brains are addled by...compassion." With such startling assertions, Hardin has cut a swathe through the field of ecology for decades, winning a reputation as a fearless and original thinker. A prominent biologist, ecological philosopher, and keen student of human population control, Hardin now offers the finest summation of his work to date, with an eloquent argument for accepting the limits of the earth's resources--and the hard choices we must make to live within them. In Living Within Limits, Hardin focuses on the neglected problem of overpopulation, making a forceful case for dramatically changing the way we live in and manage our world. Our world itself, he writes, is in the dilemma of the lifeboat: it can only hold a certain number of people before it sinks--not everyone can be saved. The old idea of progress and limitless growth misses the point that the earth (and each part of it) has a limited carrying capacity; sentimentality should not cloud our ability to take necessary steps to limit population. But Hardin refutes the notion that goodwill and voluntary restraints will be enough. Instead, nations where population is growing must suffer the consequences alone. Too often, he writes, we operate on the faulty principle of shared costs matched with private profits. In Hardin's famous essay, "The Tragedy of the Commons," he showed how a village common pasture suffers from overgrazing because each villager puts as many cattle on it as possible--since the costs of grazing are shared by everyone, but the profits go to the individual. The metaphor applies to global ecology, he argues, making a powerful case for closed borders and an end to immigration from poor nations to rich ones. "The production of human beings is the result of very localized human actions; corrective action must be local....Globalizing the 'population problem' would only ensure that it would never be solved." Hardin does not shrink from the startling implications of his argument, as he criticizes the shipment of food to overpopulated regions and asserts that coercion in population control is inevitable. But he also proposes a free flow of information across boundaries, to allow each state to help itself. "The time-honored practice of pollute and move on is no longer acceptable," Hardin tells us. We now fill the globe, and we have no where else to go. In this powerful book, one of our leading ecological philosophers points out the hard choices we must make--and the solutions we have been afraid to consider.

Book Description
"This report describes work undertaken to inform the identification of critical habitat for Peary caribou (Rangifer tarandus pearyi) in Canada, as part of the requirement for the preparation of a federal Recovery Strategy for this species under the federal Species at Risk Act. The Recovery Strategy is being completed through a separate process by the Canadian Wildlife Service. The report presents a conceptual framework outlining the steps in the knowledge assessment process to inform the identification of critical habitat for Peary caribou based on scientific and community knowledge. It describes the necessary and available data to support implementation of the framework, and uses a variety of analytical procedures and assessment criteria to evaluate and describe population condition and habitat requirements across the current species distribution of Peary caribou in Canada. While data limitations and knowledge gaps that would enhance our understanding and address outstanding uncertainties are discussed, the report concludes that the available body of knowledge is sufficient from a science perspective to inform the identification of critical habitat for Peary caribou. Methodologies to update this assessment with new information are presented, as part of an adaptive management cycle to support the recovery of this species"--Preface, p. i.
