I bought this book as it was on Bill Gates summer reading list What I read was shockingI have been to the Great Barrier Reef but found out that since I was there about half of it has gone due to ocean acidification as a result of an increase of CO2 in the atmosphereWe learn that humans have always been destructive making over 150 mega fauna mammals mammoths etc extinct due to overhunting over the millennia As our population grows and we travel around we have brought extinctions up to around 1000 times the background rate At this rate the world will be very different in 35 years and unrecognizable by the end of the centuryWe are doing the same amount of damage as an asteroid and the only way to reverse it or even slow this phenomenon is through education This is what this book provides and I sincerely believe it should be compulsory reading in schools

In the excellent THE SIXTH EXTINCTION TSE Elizabeth Kolbert briefly discusses the so called big five mass extinctions which had cataclysmic effects on earth s biodiversity These mass extinctions and their probable causes are the End Ordovician glaciation Late Devonian volcanism End Permian the warming of the oceans the rampant proliferation of a bacteria that produced hydrogen sulfide and a conseuent greenhouse effect Late Triassic ocean acidification and End Cretaceous a gigantic meteor collides with the earthSo what is the sixth extinction and why is it different The causes of the five previous mass extinctions were natural catastrophes The sixth in contrast is man made And it is occurring nowAs she discusses this sixth extinction Kolbert follows three narrative strategies Mostly she focuses each chapter in TSE on a particular animal that is extinct on the verge of extinction or that is becoming increasingly rare Then she examines the habitats and vulnerabilities of these animals and the human induced causes of their decline or demise These animals and the scourges to their existence include the golden frog a fungus harmless to African frogs that humans spread through the exigencies of pregnancy tests and fine dining great Auks overhunting corals acidification of the oceans North American brown bats another fungus this time originating with immune European bats white plumed antbirds habitat fragmentation and a conseuent reduction in army ant colonies which is their primary food and megafauna such as the mastodon and Sumatran rhino which are doomed by their long gestation periods and human predationMeanwhile her second strategy is to focus on environments In this case her subjects are oceans which are gradually becoming acidic as they absorb the carbon humans generate through burning fossil fuels and rain forests which are losing species because of global warmingFinally Kolbert examines the attempt by scientists to preserve species that are on the verge of extinction Here she visits a frozen zoo where cells of threatened species are preserved in cryogenic fluid and thereby kept viable And she discusses actual zoos that have breeding programs for rare animalsThe blurbs on my edition of TSE observe that this book is arresting riveting and powerful And they describe Kolbert s writing as masterful surprisingly breezy and engrossing All this is true and she gets the final word Today amphibians enjoy the dubious distinction of being the world s most endangered class of animals But extinction rates among many other groups are approaching amphibian levels It is estimated that one third of all reef building corals a third of all fresh water mollusks a third of sharks and rays a uarter of all mammals a fifth of all reptiles and a sixth of all birds are headed toward oblivion If you know how to look you can probably find signs of the current extinction event in your own backyard Highly recommended
