For some, water scarcity is an abstract concept, but for others, it is a harsh reality. It is the outcome of a complex interplay of environmental, political, economic, and social factors.
Freshwater makes up a tiny percentage of the total amount of water on the earth. Only 2.5 percent of the world's water is fresh, despite the fact that water covers approximately 70% of the planet. The rest is saline and based in the ocean. Even then, only 1% of our freshwater is readily available, with the majority of it trapped in glaciers and snowfields. In other words, only 0.007% of the world's water is accessible to fuel and feed the planet's 6.8 billion inhabitants.
Some locations appear to be relatively flush with freshwater because to geography, climate, engineering, regulation, and resource competitiveness, while others experience drought and debilitating pollution. Clean water is either scarce or a commodity that needs arduous labor or large sums of money to get in much of the developing countries.
WHAT WILL HAPPEN IF THERE IS NO FRESH WATER ON EARTH?
It goes without saying that the human species would perish quickly in the absence of fresh water!
The same can be stated for all animals and plants, as H2O is one of the essential building components for life to thrive. Without fresh water, all flora would quickly perish, turning the world into a brownish dot rather than a green and blue one. Because clouds would cease to develop and precipitation would end as a result, the weather would be dominated nearly completely by wind patterns.
WHAT CAN WE DO FOR SAVING OUR FRESH WATER?
RAINWATER TREATMENT: Rainwater harvesting (RWH) is the process of collecting and storing rainwater instead of letting it flow off. Rainwater is gathered from a roof-like surface and guided to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or reservoir through percolation, where it seeps down and replenishes the groundwater supply. This can help us with 70%-80% of our daily water requirements.
Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for families, as well as residential and household-scale enterprises, which are typically self-financed. Larger systems for schools, hospitals, and other buildings, on the other hand, can incur costs that can only be covered by owners, companies, and government entities.
SEAWAGE TREATMENT:Sewage treatment (also known as domestic wastewater treatment or municipal wastewater treatment) is a type of wastewater treatment that removes contaminants from sewage to produce an effluent that is suitable for discharge to the environment or reuse, preventing water pollution from raw sewage discharges. This aids in the re-establishment of groundwater levels.
It will safeguard water bodies from contamination, ensuring a more consistent supply of safe drinking water. Sewage treatment usually consists of two stages: primary and secondary treatment, with a tertiary treatment stage that includes polishing operations and nutrient removal included in advanced treatment. Using aerobic or anaerobic biological processes, secondary treatment can reduce organic matter (measured as biological oxygen demand) in sewage.
AWARENESS: Awareness should be spread among the people for saving the fresh water. With the help of campaigns, people will come to know how much each waste drop is costing us. Once the people are aware about this scarcity, they will stop wasting water and start conserving fresh water.
