The 17th Conference of the Parties (COP17) to the United Nations Framework Convention on Climate Change has just come to an end. Its effects don’t, and they literally grow. To nurture the discussion about climate change CNN Europe created the Ecosphere, a fertile soil for people to follow. The plants in the ECOSPHERE grow from your tweets tagged with #COP17. Once you have submitted a tweet about climate change the ECOSPHERE will feed it into a plant representing that specific topic or discussion – causing it to grow a little more. The available soil is infinite, and no tree has to be killed to grow more space.
