According to Livescience, 70% of the world’s freshwater supply is used for agricultural purposes, such as farms and lawns. This poses a problem for the environment because when fields are watered, the excess water flows into nearby streams or rivers. This can pollute bodies of water because the runoff is filled with fertilizers and other toxins that may be harmful to marine life. Also, some crops require more water than others. For example, cotton needs a lot more water to survive than potatoes do.
As we discussed in class, another source that requires a lot of water is the toilet. Everytime you flush, you are using between 1.6 gallons and 4 gallons of water. After this water is used, it may be treated and sanitized so it can be used in other ways, such as for watering plants.
Another common way that people waste water is through leaking and malfunctioning equipment. According to the Washington Post, Americans waste 1 trillion gallons of water each year, or 40 million swimming pools, due to leaky faucets and broken sprinkler systems. Not only is this wasteful and harmful to the environment, but it is extremely expensive for homeowners.
One way to reduce the amount of water waste in the world is to replace older toilets with more efficient ones. Also, landowners and farmers should replace their irrigation systems with sprinklers, which produce less runoff. Additionally, people should be wary of potential leaks in their faucets in order to avoid wasting any water.
