The book I have read and written notes about is a book called World Without Fish written by Mark Kurlansky and illustrated by Frank Stockton. This book is about what life would be like without fish and how to prevent that from happening. A summary of this book is: This book is mainly about how humans are hurting animal life through climate change, pollution, overfishing, and population control. At the same time, this book is also about how we as humans can avoid the extinction of animals and help the environment around us. Two central ideas in this book are unstable populations and trifecta these are the central ideas because they are repeated multiple times throughout the book with the use of motifs.
