what is one way that humans have contributed to the increase in antibiotic resistance? by giving antibiotics to livestock by using antibiotics properly by following a doctors prescription

Explanation:

When antibiotics are given to livestock, it can create an environment where bacteria are exposed to these drugs. This exposure can lead to the selection of antibiotic - resistant bacteria. Using antibiotics properly (as in following a doctor's prescription) is actually a way to prevent the increase in antibiotic resistance. Proper use ensures that the full course of treatment is given, which helps to kill all the bacteria (including those that might be on the verge of developing resistance).
