Apple has created a special Apps for Earth section on the App Store. Proceeds from all the apps listed on the page will go to help WWF's (World Wildlife Fund) effort in global conservation. As part of the promotion, several popular apps are offering bonus content. For example, Hearthstone players can unlock an exclusive mage called, Khadgar, and Candy Crush Soda Saga is holding two weekend-only themed events (April 15-17 and April 21-24). You can access the Apps for Earth section via the App Store app on your device. If you do not see the Apps for Earth banner, double tap your Home button and swipe away the App Store panel to reload the app.
