For the last few years, I’ve been helping Greenpeace build its first fully open source software project, Planet 4. Planet 4 is a global engagement platform where Greenpeace supporters and activists can interact and engage with the organization. The goal is to drive people to action on behalf of our planet. We want to invite participation and use people power to battle global issues like climate change and plastic pollution.
