If you mean our atmosphere, then it depends. If the population of animals does not increase dramatically and us humans "go greener", then the toxic chemicals in our atmosphere will lower and the atmosphere will stay healthy for millions of years. If we stay like we are now, polluting the atmosphere, then the air will get ruined within a few hundred years.
