Climate Quote by Judith D. Schwartz
““the planet’s current vegetative cover captures around 3000 EJ of the sun’s energy. This photosynthetic capacity would appear to be sufficient to feed only 3.3 billion people. The other 3.7 billion people, then, are being supported by photosynthetic energy captured in past eras, embodied in fossil fuel.””
