  • Earth would be quieter without people. The energy-driven motors would cease to work and make noise.
  • Things would not be at all like they are now. The built world humans have created would slowly disintegrate. Today, the attention humans give to man-made systems and natural enviornments allows for preservation.
  • Things would not be at all like the way they were before Europeans arrived.
  • A new normal would appear with a new set of ecosystems and natural ways to deal with pollution, or avoid it.
