Storyboard Text

  • Hi, my name is April, and my job is to keep the freshwater of my community clean. Human life has a huge impact on the environment and its resources, and I want to make sure those resources are around for a long, long time.
  • This is a pretty tough job, as industrial pollution from urban development leaks into major bodies of water on a regular basis. When toxic waste is not disposed of properly, it can wind up in lakes or rivers that we get our drinking water from.

  • Litter from humans also ends up in water ecosystems, where animals mistake it for food and get very sick before suffering a tragic death. I lead cleanup efforts regularly in order to try and limit the risks to animals.
  • Agricultural runoff is yet another huge danger to freshwater ecosystems. The pesticides used to kill weeds are washed away during storms, only to end up damaging the water quality of whatever body of water they end up in.
  • Dams are one of the lesser known threats to freshwater. They make it easier for humans to utilize the water; however, their construction interrupts the migration of many species of fish, causing populations to decrease.
  • Uh oh....
  • The water cycle itself magnifies all of the man-made problems concerning freshwater quality, for my job is made that much harder when the water is constantly picking up new pollutants and depositing them in other locations.
  • Evaporation
  • Runoff
  • Condensation
  • Precipitation
