Did you know trees can communicate?

In the movie “Little Shop of Horrors,” a young florist talks to a man-eating plant named Audrey 2 who talks back. In another movie, “The Happening,” plants and trees attack mankind in response to pollution and release neurotoxins that cause people to commit suicide.

While these sci-fi scenarios seemed far-fetched, scientists have discovered that trees do communicate with each other and mount defenses against perceived threats.
