This is an interesting take on the palm oil campaign. Melbourne zoo has a Zoopermarket section in their Orangutan section that aims to do the same thing with the app, but on a smaller scale.

Zoopermarket is a very cool idea, just checked it out now. Sallie Campbell is an incredible music and it's so lovely to see people so passionate about these causes. My friend is creating an app for zoos - so that people can donate money directly as well. A lot of good stuff happening.
