Miles O’Brien:

Well, this is something we all really need to pay attention to, Lisa.

The projections are, by 2030, our use of antibiotics, if nothing changes, will be triple what it is today. And what that means is, there are going to be many more antibiotics which become really just basically useless, more so-called superbugs out there.

And we are facing the prospect of a post-antibiotic world. We take for granted these miracle drugs, which really since World War II have just dramatically changed medicine in ways that it would take too long to enumerate right now.

But we could get back to a world, Lisa, if nothing is done, where something as simple as a cut or a blister could kill you, which is what the world was like before we had antibiotics.

So it's time — this is like a slow-motion train wreck. Researchers have been warning us all about it. And it kind of reminds me a little bit of climate change. But it's time to get a handle on this, because, right now, more than a half-million a year people globally are dying for lack of antibiotics.
