It's based on the 1972 Dr. Seuss book...the story of a crusading creature out to save the forest.
"Lorax" closely parallels the real-world plight of the orangutan, whose existance is threatened by the non-sustainable use of palm oil, a common ingredient in mass-produced foods.
The exhibit includes eight stations which relate to the Seuss book but also teach environmental lessons an an interactive, friendly way. Kids don free 3-D glasses and find secret clues left by the Lorax.
They can stop by the Lorax Loft and drop through the Orangutangle, a fun climb-down experience that gives visitors a sense of what it might be like to be an orangutan.
Then walk over to the PECO Primate Reserve where you can meet an orangutan. While you're there, you can write a thank-you message to one of dozens of corporations pledged to use only certified sustainable palm oil.
Your leaf-shaped message is posted on a tree for display, then forwarded to the company you select. Not sure which one? here's an array of products right there so you can see which of your favorites supports the cause.
"Trail of the Lorax", a partnership with . Dr. Seuss Enterprises, is free with your regular admission. It's open during regular hours through October 31st. For more information, access Philadelphia Zoo.
