I think the World Health Organization has said that antibiotic resistance could be one of the major health challenges we face, as common infections once again become common killers if we don't get this right and there are fewer new drugs coming on board. One thing we could do is to encourage people, instead of going to the doctor in search of an antibiotic for a common cold or a sore throat or something, to first go and see their pharmacist, because that, probably, will lead to better treatment and will avoid the use of antibiotics when they're not appropriate.
