The Sixth Extinction: Saving Our Planet from Ourselves

"The Sixth Extinction: An Unnatural History" is a book by Elizabeth Kolbert that explores the current mass extinction of species caused by human activities. In the book's introduction, Kolbert lays out the scope and urgency of the problem, emphasizing the fact that the current extinction rate is unprecedented in human history and is driven by factors such as habitat destruction, climate change, pollution, and the introduction of non-native species.

ABOUT AUTHOR:

Elizabeth Kolbert is an American journalist, author, and staff writer at The New Yorker magazine. She is best known for her book "The Sixth Extinction: An Unnatural History", which won the 2015 Pulitzer Prize for General Nonfiction. Kolbert was born in New York City in 1961 and graduated from Yale University in 1983 with a degree in literature. She began her career in journalism as a reporter for The New York Times, where she covered environmental issues, among other topics.

SUMMARY:

In the first chapter, Kolbert lays out the scope and urgency of the problem, emphasizing that the current extinction rate is unprecedented in human history and is driven by factors such as habitat destruction, climate change, pollution, and the introduction of non-native species. She argues that human beings have become a geological force capable of altering the planet's ecosystems on a scale comparable to the asteroid impact that wiped out the dinosaurs.

The second chapter looks at the history of extinction and the five previous mass extinctions that have occurred in the history of the planet. Kolbert explores how these past events were caused by natural phenomena such as volcanic eruptions, asteroid impacts, and shifts in climate, and how they created opportunities for new species to emerge and flourish.

In her travels around the world, Kolbert provides vivid descriptions of the various ecosystems she visits and the species that inhabit them. In Australia, she observes the bleached and dying coral reefs of the Great Barrier Reef, which are being decimated by ocean acidification caused by rising carbon dioxide levels in the atmosphere. She also notes the decline in populations of the iconic marsupial, the koala, due to habitat destruction and climate change.

In Panama, Kolbert investigates the devastating impact of the chytrid fungus on amphibians, which has caused the extinction of at least 120 species and threatens many more. She speaks to researchers who are working to save endangered frog species by breeding them in captivity and reintroducing them into the wild.

In the Amazon rainforest, Kolbert witnesses the effects of deforestation on biodiversity, as entire ecosystems are destroyed to make way for agriculture and logging. She describes the intricate web of relationships between plants, animals, and insects in the rainforest, and the devastating consequences of disrupting these relationships.

Kolbert also examines the impact of human activity on large mammals such as elephants, rhinos, and tigers, which are being hunted and poached to the brink of extinction. She visits conservation programs that are working to protect these species and their habitats, but notes the difficulty of enforcing regulations and stopping the illegal trade in wildlife products.

Throughout the book, Kolbert engages with scientists and conservationists who are working to address the extinction crisis. She highlights the challenges of implementing effective conservation strategies in the face of political and economic pressures, and the need for a global commitment to preserving biodiversity. Kolbert argues that we must take urgent and decisive action to protect the natural world, or risk losing countless species and irrevocably altering the planet's ecosystems.

EVALUATION:

One of the strengths of the book is the breadth of topics covered. Kolbert provides a comprehensive overview of the various ways in which human activity is driving the current extinction crisis, from habitat destruction and climate change to pollution and the introduction of non-native species. She also examines the impact of these factors on a wide range of species, from large mammals to small insects, and explores their interconnections and the implications of their disappearance for ecosystems as a whole.

Another strength of the book is Kolbert's extensive research and reporting. She draws on interviews with scientists, conservationists, and other experts to provide a nuanced understanding of the challenges and opportunities of addressing the extinction crisis. She also incorporates her own first-hand observations and experiences from her travels around the world, bringing a personal and engaging perspective to the topic.

However, some readers may find the book to be a bleak and depressing account of the state of the planet. Kolbert does not shy away from the severity of the problem and the challenges of addressing it, and some readers may find the book to be overly negative or lacking in hope. Additionally, while the book provides a comprehensive overview of the current extinction crisis, some readers may wish for more detailed analysis of specific conservation strategies or policy recommendations.

Overall, "The Sixth Extinction" is a highly recommended read for anyone interested in the future of the natural world and the urgent need to address the current extinction crisis. Kolbert's engaging writing style and extensive research make the book accessible and informative, and it serves as a valuable resource for understanding the complex and interconnected factors driving the extinction crisis and the opportunities for action to preserve biodiversity.
