How has the atmosphere changed over the last 4.5 billion years?

Why did the earth's atmosphere change after it was first formed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
How long will the air last?
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.
