One of the biggest errors that we as a society are committing: creating antibiotic-resistant superbugs by overusing antibiotics. It's overused in humans. But even more shocking is the indiscriminate use of antibiotics in livestock. 80% of antibiotics sold in the U.S. is not for human use, but for livestock. Farmers and ranchers routinely feed antibiotics to their animals to promote faster growth. We are creating strains of antibiotic resistant superbugs that can kill us so we can have cheaper meat. It doesn't make sense.
