One Zombie Apocalypse has already begun writes Erica E. Phillips:

• Zombies are generally thought to crave fresh human brains. The increasing amount of academic resources devoted to studying them indicates that they have been successful in attaining it.
• In the past five years there have been 20 scholarly books with the word ‘zombie’ in the title.
• JSTOR, an archive of academic journals has also recorded a significant uptick in the number of papers that refer to Zombies.
• An increasing number of college courses allow students to study zombies.
• Fields such as economics (“The economics of the Undead“), media studies (“Zombie sexuality”), and literature have tackled the subject.
• Defenders of the trend point out that Zombie studies are used to analyze more serious topics such as slavery, religion, and even post-traumatic stress disorder.
