Antibiotics are the first line of defense in protecting humans and animals against bacteria and other microbes. Microbes, like humans, want to survive. They can do that by mutating to adapt to their changing environment, unfavorable conditions and any threats they encounter — threats such as antibiotics.

Antimicrobial resistance occurs when an antibiotic no longer works against a microbe because the microbe has mutated, and its genes help it to combat or resist the antibiotic. When microbes do this, they become even more dangerous to humans and animals, who rely on antibiotics to cure infections.

Scientists have warned about the consequences of antimicrobial resistance for decades. Now, worsening climate change is making antimicrobial resistance more persistent and widespread.
