Retailers and consumers want answers about sustainability – particularly how the world’s limited tuna resources are being conserved – and we offer a library of detailed resources on the topic. But more and more the same few questions are raised: is pole & line fishing the key to sustainability? Should FADs be banned? Would marine reserves protect tuna from overfishing ? As part of our commitment to educating the public on the science behind tuna sustainability, we’ve published a series of new resources that outline the facts, detail our positions and provide the data behind our viewpoint.
Global climate change is expected to cause serious damage to coral reef ecosystems during the coming 50 years. The rising sea surface temperatures and increasing ocean acidification are so serious global threats, that even the relevance of reef rehabilitation at the local level can be questioned. The answer to those who doubt is that well-managed reefs which are relatively free of human impacts have shown resilience to coral bleaching and reef mortality. On the other hand, the badly managed reefs which were already affected by local impacts (such as pollution and overfishing), have often shown very limited recovery or no recovery at all.
Animal migration is a phenomenon far grander and more patterned than animal movement. It represents collective travel with long-deferred rewards. It suggests premeditation and epic willfulness, codified as inherited instinct. A biologist named Hugh Dingle, striving to understand the essence, has identified five characteristics that apply, in varying degrees and combinations, to all migrations. They are prolonged movements that carry animals outside familiar habitats; they tend to be linear, not zigzaggy; they involve special behaviors of preparation (such as overfeeding) and arrival; they demand special allocations of energy.
Did you know that microscopic plants can ultimately lead to vast "dead zones" in our coastal waters? Dead zones, or water with low oxygen, have been increasing throughout the world.Scientists are working hard to learn more about their causes and effects, and to find potential solutions to the problem. The following web pages are the work of a COSEE Coastal Trends Scientist-Educator Team that conducted research on dead zones at Horn Point Laboratory in Cambridge, MD during the summer of 2008. Browse the tabs or take a COSEE Modules Tour to learn more about dead zones, global and local dead zone trends, and how scientists are studying dead zones.
FUNDY'S WATERY WASTES? Pollution in the Bay of Fundy "the toxic chemicals are there, but we don't really know what effects, if any, they are having on the animals and plants. This is disturbing, given the great economic importance of the Bay's living resources, and the fact that we ourselves consume large quantities of them".

Reviews "If a book could receive a standing ovation - this one is a candidate. Sodhi and Ehrlich have created a comprehensive introduction to conservation biology that is accessible intellectually, and financially, to a broad audience - indeed it is conservation biology for all . The quality and clarity of the writing makes this book an invaluable asset to the conservationist's toolbox."
By Jonathan Safran Foer, Hamish Hamilton, 341pp, $32.95 Eating Animals. Paradise Locker Meats is a slaughterhouse in north-western Missouri, near the huge Smithville Lake. In among its lethal machinery is a painting of the facility that shows a cow running out the back.
Cracking the problem of identifying free range and organic eggs. Organic, free range, organic free range, green, eco. Confused? With so much choice in the supermarket aisle and so many ways of describing would-be green products, it can be hard to figure out what you're actually buying.
Thinking outside the lunch box ... Foer spent three years dissecting animal agriculture, including an undercover raid on a turkey farm. Photo: Caroll Taveras You wouldn't think being a vegetarian is a dangerous idea. Well, says the American author Jonathan Safran Foer, that depends on what you mean by a dangerous idea. ''There are ideas that can literally put you in physical danger, which this one can,'' he says.
