An introduction to the biology and ecology, as well as to the past, present, and future state of this majestic species...and sadly, their future doesn't look good.
This book provides an insightful look at the biology, evolution, behavior, and environmental requirements and diet, as well as a look at the past, present, and possible future of this iconic species. The Muvalney presents this information in a format that is easily followed, and which can be readily understood by non-scientists.
Mulvaney provides detailed information on the conditions required by polar bears to successfully give birth, as well as to obtain the food they need to survive in their hostile environment.
The most notable point in the book for me are Mulvaney's comments in the closing chapters on the current trend of global climate change, and the effects of warming that are happening more rapidly and more extremely in the Arctic than anywhere else on the planet. Warming of the Arctic is causing the Arctic Ocean's ice cap to retreat from coastlines earlier, move farther offshore, and stay offshore longer than any time in recorded human history. This combination of events poses a significant stress on polar bears that need access to ice floes in order to capture their primary prey - ringed seals. With the ice cap now receding 200 or more miles from the shore in some places each summer, polar bears are having to endure prolonged periods of seasonal fasting, and are showing signs of chronic undernourishment and stress.
The author also includes estimates and citations from polar bear researchers which suggest that if the current trends of climate change and their effects in the Arctic continue, our children may be the last generation to see polar bears living in the wild.
This book is more than a cautionary tale about a species threatened by conditions arising from a shifting climate, it is a snapshot of a canary dying in a coal mine.

I have been following this and related environmental issues for over 20 years...it's past time to pay attention, it's time to take action locally and globally.
