While we can probably make fuel with it, trees long ago figured out what to do with extra CO2 > [@Has science determined an optimum CO2 level?](https://boards.straightdope.com/t/has-science-determined-an-optimum-co2-level/705520/39): > > A long term well done study of trees in Maryland reported hard wood trees are growing two to four times faster now, and it is due to increased CO2 levels. > > [http://www.nytimes.com/2010/02/02/science/earth/02trees.html?\_r=0](http://www.nytimes.com/2010/02/02/science/earth/02trees.html?_r=0) > > It’s one reason experts think the missing sink (where all the CO2 is going) might just be the forests.
