That is already happening, as more microbes are learning to live within our bodies and resist our efforts to eradicate them. Eventually we can expect to see a deadly virus that decimates our population with virtually no way to stop it, leaving behind a more resistant breed of humans and a much smaller population. This could happen, literally, at any time.
Of course, a decimated population that hasn't learned from its past mistakes will only re-breed itself into dangerous numbers again, and possibly kickstart another cycle of die-offs by disease in the future. Assuming enough of a decimated population survives to bring the numbers back up.
