Our new host, Rose Kerr, sits down with Andrea Westerband, a field ecophysiologist, to find out what photosynthesis has to do with economics. Plants have to be careful where they "spend" water and nutrients during photosynthesis. Scientists like Andrea are trying to find out why and when they do this, in order to understand how plants will react to changes in climate. Even more curiously, some clues are hidden in the soil!
