In brief: Antibiotic pressure

When bacteria are exposed to antibiotics the strongest bacteria survive.
Strength is gained by genetic mutations & by acquiring resistance genes from other bacteria. This selection for resistant bacteria is called antibiotic pressure. Since the 1st antibiotic was introduced in 1935 bacteria continue to gain resistance in 'snow-balling' fashion. Some bacteria today are resistant to all antibiotics.

In brief: Multiple factors

As mentioned by dr. W- indiscriminate use of antibiotics (abx) creating an environment only resistant bugs can grow.
This can be prevented in several ways -1. Use abx for the appropriate indication, 2. Achieve source control, 3. Use abx for as short of a period needed to treat a disease. Other factors contributing to resistance is its use in poultry and cattle, and a false sense of security.
