The best thing you can do is keep informed, and keep others around you informed. Many people don't realize this is such a rapidly progressing issue. In fact, many people may not even know that they are improperly taking their Antibiotics and what the side effects are to doing so.
If more informed I feel like the public could do a bit better at turning down Antibiotics when they aren't necessary, and using them properly when they are. Just that action would go a long way.
Edit- I would also like to add that a lot of people don't realize just how easy it is to get an infection, and education could go a long way in keeping it from happening in the first place. It reminds me of that guy on reddit with the horrible case of necrotizing fasciitis that he ended up with after retrieving a football from a koi pond. His day by day imgur chronicle was both interesting and horrifying.
It doesn't have to be that way, and waiting around for "someone else to handle it" will likely lead to a Tragedy of the Commons.
Call your representatives [US: 0,1] or regional government representative (I just called my senator, and on hold for house rep now), tell them we need an emergency crash program to develop new, tightly-regulated antibiotics so that infection doesn't become the leading cause of deaths in 2025. Because it takes years and billions to develop new antibiotics, this is something companies will not pursue on their own initiative. If not, it'll be a return to the 19th century. Good luck with that.
You're not going to have new antibiotics without biotech or pharmaceutical companies helping.
The government needs to provide incentive for antibiotic research, right now regulatory and reimbursement issues are making the therapeutic area very unattractive.
