Why is it important to conserve water?

Aug 19, 2019

Conserving water means using our water supply wisely and responsibly. Water is the most essential source of life on earth. We need water in every activity like drinking, cooking, bathing, washing, agriculture etc.

About 71 percent of the Earth’s surface is water, therefore many people are under the illusion that it is an endless resource. Unfortunately, only 2.5 percent of the earths water is fresh water, the Remainer of the earths water is saltwater that we cannot consume. Saltwater can be distilled but the problem with the desalination of saltwater is it requires a lot of energy. Salt dissolves easily in water forming a strong chemical bond that is difficult to break or reverse.

Reasons we need to protect water.

Growing global population

The current average population is estimated to increase by 82 million people per year, with this continues population growth the demand for water will also increase.

Climate Change is affecting water supply

The worlds temperature has increase by 1.9 °F since 1980, and we have seen 18 of the hottest years ever recorded since 2001. The warmer temperatures will have a negative effect on the worlds already depleted water supply. The heat is increasing the rate of evaporation of water into the atmosphere, in effect increasing the atmosphere’s capacity to “hold” water. Increased evaporation will dry out some areas and fall as excess precipitation on other areas. Therefore, leading to either droughts, floods or forest fires.

Effects on agriculture

Everything including plants and animals need fresh water to grow. If there is a shortage of fresh water for agriculture there will be a shortage of fruits, vedg and livestock for humans to consume. Globally, 70% of freshwater is used for agriculture, and this is set to increase with a growing population.

Less water means sewage does not flow

When you flush your toilet, you do not think about the water that is removing the sewage away from your home, with a shortage of water this process cannot happen. This could pose a risk to human health and the environment.

Reducing water has a positive effect on global warming.

The biological process of water treatment plants results in direct emissions being generated, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as indirect emissions from energy generation. By saving fresh water we reduce the need to treat and pump excess water. This in turn leads to less chemicals, energy and greenhouse gases being generated.

These are only five out of the many reasons why water is so important for us and future generations, and how conservation is necessary going forward.
