Shadyac accomplished this by requiring crew members to plant 2,050 trees at the Rappahannock River Valley National Wildlife Refuge in Warsaw, Virginia and the San Joaquin River National Wildlife Refuge near Modesto, California. He also bought over 400 bikes for all the cast and crew, to get to work instead of driving. In addition, rather than simply demolishing sets, Shadyac tried to donate houses built for the production and had the Ark set recycled, by donating materials to Habitat for Humanity. During the premiere of the film for cast and crew at Universal Citywalk, the attendees were encouraged to donate to a campaign to plant trees in forests around the world. The after party used recycled cups and plates to offset the use of resources. Shadyac also required that when Industrial Light & Magic developed the climactic scene, that the CGI flood did not appear to harm any of the trees in the scene.
