One of the most underrated global issues nowadays involves the looming scarcity and eventual shortage of our water resources. The lack of such supply is dangerous as it can lead to drought and, worst, the extinction of humanity.
Water may be abundant in nature, but it is limited in supply. Lots of people are not aware of this because of the continuous flow of water to their homes. It’s important that we, as humans who use such natural resource, should know why and (most especially) how we should conserve it.
Below are some of the scariest facts about water that will push you to conserve it genuinely.
Climate Change Significantly Affects The Water Cycle
We have all learned this from our Earth Science classes. Water goes through a complicated process called the water cycle. As we all know by now, man did not create water. It is stored on the planet and is just being used and reused by every living thing.
The water cycle involves three processes, namely, evaporation, condensation, and precipitation. The sun is the main reason why there is such. It heats the water from the bodies of water especially from the oceans causing it to evaporate. The vapor then rises into the air and condenses into clouds.
As air currents move around the globe, cloud particles collide with each other causing precipitation in the forms of rain, snow, or even glaciers. Most of these will fall back to the bodies of water (oceans, rivers, and lakes, among others). These surface runoffs are usually what we call freshwater.
Climate change affects the first part of the cycle which is the evaporation stage. Put simply, the now warmer air temperature causes more water to evaporate. With more vapor in the air, there will be more intense rainstorms. What comes next is great flooding in the cities and the whole country.
The Water Treatment Process Is Not As Easy As It Seems
We all obtain even our drinking water needs from the nearby oceans, rivers, and other available bodies of water. Generally, when raw and fresh, these are not safe for drinking. Our flowing water, before reaching our homes, undergoes another process called the water treatment.
The first step of the water treatment process involves coagulation and flocculation. In this stage, positively charged chemicals added to the water neutralizes the negative charge brought about by dirt and other impurities in the water.
The next stages are called the sedimentation and the filtration. After the neutralizing, the resulting clear water will now pass through varying filters (sand, gravel, and charcoal) to further remove unwanted particles, bacteria, and viruses. After this, the water will undergo disinfection where another a disinfectant is added to kill remaining parasites and bacteria.
Small Rivers And Lakes Are Disappearing Entirely Due To Increased Water Demand
Smaller lakes and rivers are also disappearing slowly because of climate change. Warmer air temperature turns them all into water vapor. Uneven distribution of air currents brought about by climate change, however, turns it into excessive precipitation in other places.
Excessive water withdrawal is also a cited reason why our small bodies of water are “drying up.” Lack of proper management of water and control will lead to this. The authorities may already be taking steps against its causes, but decreasing unnecessary water use at home is still our major responsibility.
The demand for water is getting higher now that the population is also rising, amidst all these facts. Extensive research in hydrology may seem to be the answer, but each one of us has a significant contribution. That is evident through water conservation.
