...fins and scales enable some species of tuna to swim as fast as 43 miles per hour. Tuna swim incredible distances as they migrate. Some tuna are born in the Gulf of Mexico, cross the entire Atlantic Ocean to feed off coast of Europe, and then swim all the way back to the Gulf to breed. These extraordinary marine animals are also integral to the diet of millions and are one of the most commercially valuable fish. The majority of the market is made up of four species: skipjack, yellowfin, bigeye and albacore. As the methods of catching tuna have improved over the years, the conservation and management of tuna has not evolved as quickly. According to the United Nations Food and Agriculture Organization, most tuna stocks are fully exploited (meaning there is no room for fishery expansion) and some are already overexploited (there is a risk of stock collapse). The once abundant Northern Bluefin Tuna (Thunnus Thynnus), which lives throughout the Atlantic Ocean and the Mediterranean Sea, is plunging in a free fall towards extinction. The Northern Bluefin Tuna population has a slow growth rate and also a late sexual maturity age. Bluefin larvae have a 1 in 40 million chance of reaching adulthood, an extremely low number for an endangered species. The Bluefin mature at around 8 years old, and are then able to reproduce; because of this, the Bluefin population is not growing at a fast enough rate in order to keep itself from becoming extinct. Greenpeace Red List lists the Bluefin as critically...

..."Why is Sex Fun? is the best book on the subject I've read. This lively exploration of our sexual heritage offers fascinating reading for anyone curious about why lovers do what they do." -Diane Ackerman, author of A Natural History of the Senses "I am so jealous of Jared Diamond, for he writes with such an elegant simplicity! Here, he takes a loot at the endlessly fascinating topic of human sexuality His convincing arguments should persuade xm that there are very special reasons why we evolved to use sex for recreation as well as for procreatim whereas most other mammals are denied that pleasure.... It is a great little book, by one of the worlds foremost biological philosophers." -ROGER Shohl Professor of Physiology Monash University Australia "Once again Jared Diamond provides us with answers to questions we may never have stopped to ask, but wish we had. In this long essay Diamond explains that recreational sex, while not unique to humans, is a rare behavior in the animal world. Above all, we learn, sexual activity divorced fron procreation is not only part of what it is to be human, but the very crux of our evolutionary success." -Bettyaxn Kevles. author of Naked to the Bonn Medical Imaging in the Twentieth Centnty The Science Masters Series is a global publishing vonture consisting of original science books written by leading scientists and published by a worldwide team of twenty-six publishers assembled by John Brockman.

...UNIT I DEFORESTATION CHAPTER 1 What is deforestation? Deforestation is the removal or damage of vegetation in a forest to the extent that it no longer supports its natural flora and fauna. In other words, deforestation can be defined as the transformation of forest land to non-forest uses where forest land includes lands under agro-forestry and shifting cultivation, and not simply closed canopy primary forests (FAO/UNEP, 1982). However, this definition does not include “logging”. More inclusive was Myers’s 1980 definition, where deforestation refers, “generally to the complete destruction of forest cover through clearing for agriculture … [so] … that not a tree remains, and the land is given over to non-forest purposes … [and where] very heavy and unduly negligent logging … [result in a] … decline of biomass and depletion of ecosystem services … . So severe that the residual forest can no longer qualify as forest in any practical sense of the world.” Alan Graigner (1980, AS quoted in Saxena and Nautiyal, 1997) asserts that selective logging does not “lead to forest clearance and does not constitute deforestation”, whereas Norman Myers (1980, 1993) thinks that logging is crucial because, although it may only affect a small proportion of trees per hectare, it damages wide areas and is the precursor of penetration by the forest farmers. For the purpose of this study, the FAO’s latest definitions (1993) will be used. The FAO defines forests as “ecosystems with a minimum...

...1. Introdution:- When a car is speeding along at 50 Km per hour it has a tendency ('Inertia') to keep moving at the same speed and in the same direction unless some force acts on it. The car accelerates its occupants to its own speed so that they seem to be moving as a single unit. The inertia of the occupants is, however, independent of the inertia of the car. If the car were to crash into a tree, the force of the tree would bring the car to an abrupt halt. The speed of the occupants, however, would remain the same because of their independent inertia and they would bang into the steering wheel, the dashboard or the windshield. The force exerted by the steering wheel or the windshield would then bring the occupants to a stop but may in the process cause injury to vulnerable body parts such as the head and the face. Car manufacturers use 2 different restraint systems to help stop the occupants while doing as little damage to him or her as possible. The oldest one is the seatbelt that spreads this stopping force across sturdier parts of the body over a longer period of time to minimize damage. The air bag is the second and a more recently developed system that is used to deploying a rapidly inflating cushion in the space between the passenger and the steering wheel or dash board to prevent crash injuries.

...The Marine Environmental Impacts of Artificial Island Construction Dubai, UAE By Bayyinah Salahuddin Date: _______________ Approved: _________________________ Dr. Michael Orbach, Advisor Masters project submitted in partial fulfillment of the requirements for the Master of Environmental Management degree in the Nicholas School of the Environment and Earth Sciences of Duke University 2006 ACKNOWLEDGEMENTS ﻷﺟﻞ أهﻠﻲ First, I thank Allah for making my research successful and rewarding. Next, I would like to thank my dear family for their generous, unwavering support and encouragement. Finally, I would like to thank the Student International Discussion Group and the Environmental Internship Fund at the Nicholas School of the Environment and Earth Sciences at Duke University for funding my research. -2- ABSTRACT In the United Arab Emirates, Dubai is building three colossal artificial islands— each in the shape of a palm tree—in the Arabian Gulf. This has prompted several other Gulf countries to construct artificial islands. To determine the impacts of the first of these Palm Islands, The Palm Jumeirah, I traveled to Dubai and interviewed governmental agencies, environmental groups, and the developer’s environmental scientists. I analyzed the island’s impacts on marine wildlife as well as the developer’s mitigation efforts and the developer’s compliance with the relevant environmental laws. The Palm Jumeirah has buried and asphyxiated wildlife, increased turbidity, and changed...

...RICHARD DAWKINS-The Selfish Gene. Ebook v1.0. 'Who should read this book? Everyone interested in the universe and their place in it.' Jeffrey R. Baylis, Animal Behaviour Our genes made us. We animals exist for their preservation and are nothing more than their throwaway survival machines. The world of the selfish gene is one of savage competition, ruthless exploitation, and deceit. But what of the acts of apparent altruism found in nature-the bees who commit suicide when they sting to protect the hive, or the birds who risk their lives to warn the flock of an approaching hawk? Do they contravene the fundamental law of gene selfishness? By no means: Dawkins shows that the selfish gene is also the subtle gene. And he holds out the hope that our species-alone on earth-has the power to rebel against the designs of the selfish gene. This book is a call to arms. It is both manual and manifesto, and it grips like a thriller. The Selfish Gene, Richard Dawkins's brilliant first book and still his most famous, is an international bestseller in thirteen languages. For this new edition there are two major new chapters. 'learned, witty, and very well written...exhilaratingly good.' Sir Peter Medawar, Spectator Richard Dawkins is a Lecturer in Zoology at Oxford University and a Fellow of Mew College, and the author of The Blind Watchmaker. Preface to 1976 edition This book should be read almost as though it were science fiction. It is designed to appeal to the imagination. But it is not science...
