LOS ANGELES (AP) -- Walt Disney Studios is turning box-office cash from its nature documentary "Earth" into seed money to plant trees in the rain forest.

Disney had announced it would plant one tree in Brazil's endangered Atlantic rain forest for every viewer who saw the movie during its first week. According to Disney, the box-office tally hit $16.1 million, which translates to 2.7 million trees.

The trees are being planted by the Nature Conservancy, which is trying to reforest 2.5 million acres in the rain forest.

"Earth" is narrated by James Earl Jones and follows a year in the lives of three families of polar bears, elephants and humpback whales.
