What we lose if we lose antibiotics

Question - I have heard for years about the misuse of antibiotics in livestock farming. How it is going to end our ability to use antibiotics etc etc. Is there some scientific stuff out there that supports this? If so, by how much?

Instinctively I am inclined to believe it, but human instincts are notoriously unreliable predictors of scientific accuracy (it seems obvious that the sun rotates around the Earth, it’s the one moving isn’t it?)
