I don’t think antibiotics are likely to cause human extinction. Or at least I hope not!
I suppose in theory if we continue to overprescribe antibiotics and bugs mutate to fight all treatments we have then they could become unstoppable.
There’s research going on at the moment to find other ways to kill bacteria. One example is scientists are trying to make ‘predatory bacteria’ which actually attack bad bacteria. Fingers crossed someone sorts this out before we’re extinct!
I don’t think antibiotics themselves could be a cause for human extinction. If bacteria do become resistant to all antibiotics, it’s possible that there would be a large effect on human populations, but like Jonny said I don’t think humans would go extinct entirely.
