The Sun about 4.5 billion years old and in about another billion years will have used up the hydrogen particles in its core and will have to use the ones closer to its surface which will make the sun's surface hotter and possibly make Earth impossible to sustain life. When the sun reaches its next phase, a Red Giant, life on Earth should be extinct, for the sun will have completely engulfed the Earth. I think using gravity from big bodies in space, such as passing meteoroids, to launch us further away from the sun every few million years or so to avoid the effects of its growth and increased combustion is a good idea. Any other ideas?
