The book which keeps a record of all the endangered animals and plants is?

The book that keeps a record of all endangered animals and plants is known as the “Red Data Book” or the “Red List.” This publication is maintained by the International Union for Conservation of Nature (IUCN) and lists species that are at risk of extinction globally. It categorizes species into different levels of threat, such as Critically Endangered, Endangered, and Vulnerable, based on their population size, trends, and distribution. The Red List is a crucial tool for conservationists and policymakers in assessing and prioritizing conservation efforts for endangered species worldwide.
