Give the huge amount of pollution on sea and land, landfills, waste all around..no its not too clean. As for abacteria..if the earth was too clean ( had less bacteria) things would not rot..rubbish would never degrade, neither would we..so i think..if we stop polluting so much the earth is just clean enough for us to get by,

so does that mean that if there was less bacteria we would live longer?
