For the next few days, you can help save the planet with your thumbs. Apple and the World Wildlife Fund (WWF) teamed up to launch the Apps for Earth initiative. As part of the Earth Day project, Apple will donate all the money earned from the downloads of 27 participating apps and in-app purchases to WWF’s various conservation efforts.

Last year Apple and WWF announced a “multi-year partnership,” kicking it off with an effort to conserve forests in China. They’re building on that with Apps for Earth, and WWF added some additional features to their official app for the program. Users can explore a 360 degree view of Earth from outer space, as well as get up close and personal with 16 different animals. They can also snap a photo with an origami Earth and share it on social media to show support for Apps for Earth and encourage others to donate.

The other participating apps will offer new content educating users about environmental issues such as climate change and conserving water. For example, in SimCity Buildit, users can design habitats for endangered animals. In Trivia Crack, users can take a test to see how much they know about the environment. Other participating apps include Angry Birds 2, Yoga Studio, and VSCO. You can find a full list of participating apps here.

President and CEO of WWF US, Carter Roberts said, “With rich creativity and extraordinary reach, this campaign will engage hundreds of millions of people. To succeed in our work, we need big ideas with big impact. Apps for Earth delivers on that in an unprecedented way and we couldn’t be more excited about it.”
