The Cycles of Matter: What Describes the Negative Impact of Human Water Use?

According to the Water Cycle definition, water is continually evaporating, condensing, freezing, and melting.

  • Evaporation: **Water is a natural resource that covers 70% of the earth, and is fundamental for all living things. In this process, heat causes water in lakes, ponds, and other bodies of water to evaporate. The water vapor rises into the atmosphere. Once in the atmosphere, water can exist in the form of clouds. In this state, water can be removed from the earth's surface by precipitation, after having been in the water cycle.
  • Condensation: **Water vapor condenses to form clouds and rain. If condensation occurs below the clouds, precipitation falls as snow or freezing rain.
  • Freezing: **Liquid water cools into ice without outside help. For freezing to occur, the temperature needs to fall below the freezing point of water.
  • Melting: **Snow and ice melt because warmer temperatures cause the freezing point to be exceeded.

Use of Fertilizer

Fertilizer is a type of planted chemical, often containing fertilizers, inorganic fertilizer, organic fertilizer, and pesticides. The three most commonly used fertilizers are nitrogen, phosphorous, and potash.

It is important to note that fertilizers are very important for plant growth. However, certain fertilizers can cause damage to human health and can pollute the environment if not used correctly.

Exposure to fertilizers can cause damage to the eyes, skin, and brain. In some situations, pesticides can also make people sick or kill them.

Consequences of Human Water Use

Polluted water is considered one the major public health concerns of the 21st century. The world is facing the challenge of providing drinking water to its ever-growing population. We are quickly depleting our ground water resources. Western nations are over-exploiting their supplies and our use of water worldwide has tripled, since the 1900's. As our population continues to advance, so does our water consumption. In order to meet this global demand for water, many people are using the ground water sources. This over-consumption is causing the land to subside and the water within this aquifer to be released. This is the process known as a “drowning river”. When the water is being pulled into the ground at one end of river, it's being released from the aquifer at the other. The ground can start to subside until the soil collapses. The state of Florida has already experienced a few of these “subsidence events”. Other negative impacts of over-pumping include salt water intrusion, water supply reductions, earthquakes and pollution.

You don’t have to be a scientist to understand the negative consequences of human water use. Water is considered a finite resource, and this finite resource is reducing at an alarming rate. If we do not work together as a community and reduce the water we use a serious problem will happen.

How to Stop Water Pollution?

Water pollution is a serious issue. Water bodies are being polluted by human activities in several folds. One of the biggest threats to our water body habitats is water pollution. Water pollution does not only include water conversion but also may include the dumping of harmful chemicals.

One of the largest contributors to water pollution is the discharge of sewage, industrial waste, and oil by many industries. The impact of water pollution is very significant when it comes to marine creatures. Marine creatures have a high level of sensitivity towards acidic waters.

The release of chemicals like oil and solid waste from industries have a direct impact on our water bodies.

Oil spills in the sea and river lead to oil and solid debris.

In many cases, after the release of these substances; the flow of water is altered by the creatures.

Fish and marine animal's leading cause of death in India, in most cases, leads to its natural predator.

The havoc that is created by the discharge of industrial waste has a very huge impact on the marine life. The release of heavy metals from these plants lead to the buildup of pollutants in the water.

In many cases, fish and other species of marine animals that are not pollution-tolerant are starting to die.

Even people have been found to drink such contaminated water on a larger level. People that consume contaminated water have actually died or have had severe health issues.


Water pollution is a serious issue and affects humanity in many ways. While there's no cure to this water-borne illness, the prevention of it can be kept low, by simple steps that everyone should take, such as having good water filters installed in your home. We do this when we buy water bottles in the shops and we should also do this with our home water supply. Filters can be purchased online and you can make sure that you are drinking clean, fresh and healthy water.

Water pollution can be kept under control and you can enjoy the benefits of it, such as drinking the clean, fresh and healthy water in your home and avoid liver and kidney ailments. Water treatment in this way benefits society in the long term.

Human Wastewater

It is hard to believe that the waste generated from a single flush of a toilet contains the same amount of nutrients as a full meal for an adult.

Animal Wastewater

  • Unfortunately, runoff from animal farms and other facilities also contains animal waste.
  • For more information on manure management visit EPA.gov

Nutrient Pollution

The runoff from agricultural lands contain a higher concentration of nutrients. This runoff will move into nearby waterbodies and produce eutrophic water conditions. This results in an increase in algae, weeds, bacteria, and other organisms that deplete the quality and quantity of the water. This is harmful not only to the ecosystem, but may also be fatal to humans depending on the levels consumed. Animal effluent poses the same threat.

Nonpoint Source runoff is the most challenging pollutant. NOx downstream.

Since its source is often unknown, there is no end in sight for its destruction of water quality.

Municipal Water Use

Municipal water use is the largest source of water pollution in the US.

Many cities are realizing the importance of conserving their water systems.
