Update: On March 4, 2016, the U.S. Forest Service announced that it was rejecting a permit application to build infrastructure through a national forest near the Grand Canyon. These roads would have enabled a megadevelopment with 2,100 housing units and 3 million square feet of commercial space including hotels, a spa, and a conference center. This decision was made two days after Sierra Club launched the video campaign below in collaboration with our entertainment partners.

Ty Burrell and Nolan Gould, father-son duo on the TV sitcom Modern Family, are big fans of the Grand Canyon. So when they heard about a massive mega-development being planned near the South Rim, they decided to do something that'll really grab people's attention.

Check them out in Ty And Nolan Save The Grand Canyon.

Then tell the Forest Service you want to see #CampgroundsNotMalls at the Grand Canyon: sc.org/GrandCanyon.
