The rich Mesopotamian marshlands known for centuries as the Fertile Crescent have shrunk 90 percent in recent years, a new study shows.

Now that the Prison Service plans to close the stud farm, there is concern that the breed may slip into extinction.
Participants in the Geographic Bee have always differed in age, ethnicity, religion, and gender.
