( CNN ) -- For three days from June 20 , heads of states , business leaders and civil society representatives will gather in Brazil to tackle the world 's environmental problems at Rio+20 , the United Nations Conference on Sustainable Development . CNN International is inviting you to join the global discussion on climate change by using ECOSPHERE , a digital tool that will visualize Twitter conversations around the Earth Summit in a stunning evolving environment . The computer-generated `` living sphere '' is built using a state-of-the-art 3D platform called WebGL -- users are recommended to access the web-based interactive ecosystem with the latest versions of Firefox , Google Chrome and Safari ( with WebGL enabled ) . If you do n't have the latest browser and graphics card you can still see ECOSPHERE at work in a live stream on the same site . 'Plant your thought , watch the discussion grow ' The ECOSPHERE takes thousands of tweets from around the world and visualizes them in real time in the form of an evolving digital garden . The process is simple : Anyone sending out tweets that they want included must add the # RIO20 hashtag . Submitted tweets are scanned for keywords and then grouped together into specific topics or discussions . Each tweet stimulates growth in a plant or tree in the garden , forming conversations . New thoughts are planted as seeds , which will grow as similar ideas are shared . The size , color and growth of these plants give users a real-time view of how the global discussion is evolving . More from Road to Rio . At any time in the evolution of the ECOSPHERE , there are up to 30 plants growing on the surface of the sphere , representing the 30 most popular keywords or topics . Users can explore the lush 3D environment by zooming in on the different branches while a separate time line documents the development of the discussions and the ECOSPHERE environment itself . The website was first launched in 2011 at the the United Nations Climate Change Conference in Durban . It was recently awarded with two Cannes Lions at the 59th International Festival of Creativity -- Silver Lion in the `` Publications & Media '' category and Bronze Lion in the `` Best Integrated Campaign Led by Promotion and Activation '' category . Earlier this year , it won gold and silver prizes at the ADC and Clio Awards in New York , at the Montreux Festival , at the ADC of Europe Awards in Barcelona , as well as with the Grand Prix of ADC Germany .
