Endangered: Biodiversity on the Brink by Mitch Tobin
Join Mitch Tobin both physically and historically as he takes us through the skirmishes, battles, and wars to save the species and the planet. He reveals the back story on the California condor, snail darter, the spotted owl, the Mexican wolf, and other species we know only because their survival would somehow block progress through his research on the Endangered Species Act. This book is a stark reminder that there are still battles to be won and other fronts opened because of our societal response to it and climate change. His writing is companionable as a fireside story and simultaneously razor sharp with journalistic fact checking. I now mourn for the bleak future of the humpback chub because of what I have seen in this book. This book is an excellent overview and introduction to the status of endangered species for all audiences. 

The Atlas of Endangered Species: Revised and Updated

This book is an excellent overview of the plight of our planet’s inhabitants; mammals, birds, fishes, reptiles, invertebrates and plants. It does not list each animal or species but rather it lists them by groupings. It should be required reading for our youth. It’s sadly an eye opener for most of us who know little about our endangered species.

Endangered: Wildlife on the Brink of Extinction by George McGavin

McGavin is the Acting Curator of Entomology at Oxford University’s Museum of Natural History and has researched the world on the topic. Drawing upon his considerable expertise, ENDANGERED is more than a simple rehash of extinction theory as he deftly examines the different types and scales of extinctions and their consequences.

Endangered is the kind of book which has dual appeal: to public libraries seeking an eye-catching overview for general-interest patrons, and to high school and college-level libraries interested in debating the progress and effects of extinction. This is must-read book for everybody. It tells you in plain simple language what is happening to these animals at the hands of man. It is a well illustrated and informative book. You will be left wanting to do something to save every single creature mentioned in the book.

The biggest threat to life on earth nowadays may just be global warming. The Clean Air Act is just one of the laws the aims to counter this adversary. In 1970, a much strong Clean Air Act was passed. This has resulted to significant improvements in human health and the environment in the US. The six commonly found air pollutants have decreased by more than 50 percent. New cars are now more than 90 percent cleaner. Ozone-depleting chemicals are also no longer being produced. There has also been 70 percent reduction in air toxics from large industrial sources, such as petroleum refineries, chemical plants, and paper mills. This is even though the U.S. domestic growth product has tripled, energy consumption has increased by 50 percent, and vehicle use has tripled already.
Another law that provides protection to endangered species is The Endangered Species Act or ESA. The Endangered Species Act that was passed in 1973 provides broad protection for species of fish, wildlife and plants that are listed as threatened or endangered in the U.S. or elsewhere. An endangered species is protected in a variety of ways in this act:
