People Around the World Are Using Far More Antibiotics. Here's Why

The use of antibiotics in humans has increased 39% from 2000 to 2015, according to a new report. The finding raises concerns about the growing threat of antibiotic resistance — where infections no longer respond to the drugs used to treat them, in part because antibiotics are overused in both humans and animals.

Economists estimate that if nothing changes, up to 10 million deaths globally could be attributed to antibiotic resistance by 2050.
