Understanding Species Conservation Status

The video tutorial explains the differences between extinct, endangered, and threatened species. It provides examples of each category, such as dinosaurs for extinct, blue whales for endangered, and polar bears for threatened. The tutorial also discusses additional categories like vulnerable and critically endangered, explaining the criteria for each based on population decline. The concept of 'extinct in the wild' is also covered, highlighting species that survive only in captivity. The video aims to clarify these terms and their implications for species conservation.

What is the main reason people often confuse the terms 'extinct', 'endangered', and 'threatened'?
