Some male fish in the river mysteriously have eggs.” (Fears, 2012) Based on this comments, I think the two main environmental problems are the threat to species and water pollution with water born viruses such as pathogen being the serious threat. “nearly a billion people around the world are exposed to waterborne pathogen pollution daily and around 1.5 million children mainly in underdeveloped countries die every year of waterborne diseases from pathogens. Pathogens enter water primarily from human and animal fecal waste due to inadequate sewage treatment.” (Dorsner, 2017) That in mind, the possibility of decrease
