A number of the thermal vents in Yellowstone release high levels of carbon dioxide, the very gas that is building up in our atmosphere.
Carbon dixoide is a crucial element for photosynthesis, and some have argued that the growing levels of this gas will make the world greener, better. Unfortunately they tend to work for energy companies. Now scientists are checking out the plants that grow next to the vents. Preliminary evidence is that they photosynthesize less efficiently and lose more water to the air.
