  20. 20. Conclusion
  21. 21. Water pollution is a growing concern in society today. As water is a vital resource to sustain humanity, it needs to be conserved. Agricultural practices that cause water pollution should be reduced or eliminated and other alternatives should be utilized in order to combat this growing problem in society today. It is the eleventh hour and we need to take action before it is too late.
