Now a new study shows a new disturbing side effect of human consumption of drugs in wildlife. A new study by scientists at the University of Wisconsin-Milwaukee found that male fathead minnows became altered behaviorally after exposure to Zoloft and Prozac. In some cases the minnows became super aggressive and killed female minnows.
Studying human-environment interaction is incredibly difficult. There are just so many interrelationships we have no clue about. In the case of medicine and negative side effects in wildlife we need to reevaluate the types of drugs and the amount consumption of said drugs at societal and individual levels if we desire to be better stewards of the environment.
