London animator/illustrator Yukai Du‘s second TED-ed lesson is possibly the most lush and relaxing explainer video of all time. This four and half-minute animated film, written by UC Davis ecologist Richard Karban, demonstrates how plants communicate with each other especially when they’re under attack.

Watch Yukai’s previous TED-Ed lesson “The Torturous History of the Treadmill.”
