Nature film fans got more than just a movie when they bought their tickets to see Disneynature's Earth, because Disney promised to plant a tree in the Brazilian Atlantic Forest for every person who saw the film during its opening week. The film hit the theaters on Earth Day, and raked in $16.1 million at the box office its first week -- which means Brazil will soon have 2.7 million new trees!

The trees will be planted as part of The Nature Conservancy's Plant a Billion Trees program, which seeks to reforest 2.5 million acres of the Brazilian Atlantic Forest. According to The Nature Conservancy, only 7 percent of this once-vast forest remains -- which is why the nonprofit wants to plant 1 billion trees there in the next 7 years.

The tree tally on the Plant a Billion Trees site's still less than 1.6 million; I imagine adding Disney's 2.7 million trees to the forest will take some time. While that happens, you can still catch Earth in theaters. Narrated by James Earl Jones, Earth follows three animal families — polar bears, elephants, and humpback whales — to combine “rare action, unimaginable scale and impossible locations by capturing the most intimate moments of our planet’s wildest and most elusive creatures,” according to the film's website.
