@glynmoody and the outflow from sewage goes into ... Which is used by animals that get infected so need treatment by antibiotics so yes farmering is a problem but is it a consequence of our profligate use, rather than the source of the problem.
I'm also unimpressed by the mass incarceration of animals as the most profitable way to rear them. And act as incubators for infectious diseases....again the fault is the human end.....
