RESEARCH PAPER: How much does water mean to you? Is drinking water becoming increasingly scarce these days? What chemicals in water affect so many organisms? Water is undeniably the most abundant resource we have on Earth, and yet it is becoming the most polluted thing there is. Water is affected not only by humans but also by animals. These causes could be avoided. Water pollution comes from litter, chemical leaks into the water, ships and oil spills. Water pollution has a significant effect on organisms that live in water. Excessive amounts of nitrogen are found in water, from runoff from chemicals applied to fields. Some prescription medications are also found in water and harm organisms such as frogs. The chemicals cause mutations in organisms, such as frogs, which develop both male and female parts. Water pollution negatively impacts our drinking water and the water we and other organisms need every day..
