How should I design a poster to show CO2 sequestration for a competition?
A good design could be one that uses flow chart symbols to diagram the various processes that are currently being researched to absorb excess CO2 from the atmosphere and store it for an indefinite amount of time. Another alternative would be to section off the poster so that the poster compares natural processes that absorb and/or mineralize CO2 to engineered methods such as carbon sinks, artificial trees, etc. If you have been given the option to present more than one poster, it will definitely be less confusing to dedicate one poster for each method. Another poster to consider could be one that displays a graph of the rates at which each method you diagram can remove carbon dioxide from the atmosphere.
