A time capsule is presented during the historic COP15 Climate Change Conference filled with 'Love Letters to the Future'. The letters are personal messages to future generations, to be unlocked in 100 years. Messages from people all over the world are specially encoded and stored in the time capsules as part of a Greenpeace project in cooperation with Emmy Award winning Xenophile Media. The goal is to make regular people, as well as politicians, think about climate change and the future. Love Letters to the Future is part puzzle, part story, part activism.
