Red Data Book Contents

The Red Data Book (often referred to as the Red List) is a publication by the International Union for Conservation of Nature (IUCN).

Its primary purpose is to document and raise awareness about species that are facing a high risk of extinction.

Therefore, the Red Data Book specifically provides data on endangered plants and animals.

Analysis of Options:

• Option 1 (red lions) and Option 4 (red birds) are too specific and don't cover the broad scope.
• Option 3 (list of plant and animals) is too general; the Red Data Book focuses on threatened ones.
• Option 2 (endangered plants and animals) accurately reflects the content of the Red Data Book.
