Vegetarians need not worry yet—plants will be on Earth for a long time to come. But not forever. The sun will ultimately determine the long-term existence of life on Earth. Its total energy output, called luminosity, has been increasing over epochs and eons by about 10% every billion years—determining much of Earth's surface temperature. This will continue for billions of years in the future.
