What are the main sources of antibiotic resistant diseases and how does antibiotic overuse play into that? In terms of overuse, who or what industries are the largest users of antibiotics?
Antibiotic resistance is the ability of bacteria to resist the effects of antibiotics that were once effective in treating infections. The main sources of antibiotic-resistant diseases include:

- Overuse and misuse of antibiotics: The overuse and misuse of antibiotics can lead to the development of antibiotic-resistant bacteria. When antibiotics are used too often or for non-bacterial infections, they can kill off beneficial bacteria, allowing resistant bacteria to thrive.

- Agricultural use of antibiotics: Antibiotics are often used in agriculture to prevent and treat infections in livestock, which can contribute to the development of antibiotic-resistant bacteria that can be transmitted to humans through food.

- Poor infection control practices: Poor infection control practices in healthcare settings can contribute to the spread of antibiotic-resistant bacteria between patients.

- International travel and trade: International travel and trade can contribute to the spread of antibiotic-resistant bacteria across borders.

Antibiotic overuse is a major contributor to the development of antibiotic-resistant bacteria. When antibiotics are overused, bacteria are exposed to the drugs more frequently, increasing the likelihood that they will develop resistance. In addition, overuse of antibiotics can lead to the killing off of beneficial bacteria in the gut, which can create an environment that is more conducive to the growth of antibiotic-resistant bacteria.

In terms of overuse, the largest users of antibiotics are the agriculture industry and the healthcare industry. In agriculture, antibiotics are used to prevent and treat infections in livestock, which can lead to the development of antibiotic-resistant bacteria that can be transmitted to humans through food. In healthcare, antibiotics are often overprescribed, leading to the development of antibiotic-resistant bacteria in hospitals and other healthcare settings. However, overuse of antibiotics by individuals can also contribute to the development of antibiotic-resistant bacteria.
Why can't we just make better antibiotics?
