Why should we try to improve the use of today's antibiotics?

Because as of right now the over use of antibiotics will lead to the bacteria developing a resistance and eventually an immunity which is bad for obvious reasons

We should try and improve the use of antibiotics because so many people are in need of many medications but are unable to get access to the things they need. Antibiotics can prevent many sicknesses, people just need to know how to use them and learn about the positive affects.
