If the earth had a diameter of 1.27 cm, the sun would be 15,000 cm away. In between would be: Nothing! The next solar system with a planet would be about 270 times as far away. Maybe we can travel that far in the future. But would we protect this planet better? Until further notice this earth is our only life support system.
We have to be smarter than a mildew that only survives until the breeding ground is depleted!
