Episode 70 Overview

We jump right into the topic of Endangered Species with a review of the ZooBooks® Issue on Endangered Species. This issue explores the animals in danger of extinction, the causes of their endangerment, and the organizations working to prevent the extinction of species by various means. (We explore what these organization do in detail in Episode 71).

Please NOTE

Due to an error in reading the tele-prompter, the opening of this episode is a bit confusing. My comments made it sound like the publication Zoo Books® was responsible for animals being endangered! Of course that makes no sense. My script was written for me to say…

…….but the rate of extinction has increased dramatically since the Industrial Revolution have had a negative impact on the habitats of animal and plant life…..

My words came out something like …..Zoobooks have had a negative impact…. Naturally, I regret this error. I think I was reading a note on my script to hold up the copy of Zoobooks’ Endangered Species edition. I’m sorry for any confusion, and I certainly hold Zoobooks® in high regard.

Back to the Overview

Since we use birds as examples of endangered species, this episode includes a video about birds – a 10-minute video presentation. We further feature books by National Geographic® that focus on places that preserve habitat for endangered species. We list books with their ISBNs below on this web page. We spotlight birds that have recovered from endangered status – more success stories of the Endangered Species Act and the Environmental Protection Agency(the ESA and EPA respectively). Herons and egrets are good examples, featuring photography by Cal Holman (

This episode also features Ducks Unlimited, one of the first private organizations to protect habitat and support hunting regulations for waterfowl. That brings us to hunting and the role of guns, which inspired commentary from host John Letz about the role of hunters in managing wildlife and on the need to limit war-type weapons that allow the murder of so many victims in school shootings.

Germane to the report on an animal, we explore how to find and report the conservation status of animals from Wildlife Cards® and other sources – focusing on the language used for communicating this information.
