Debate on life of human beings without fresh water
- Generally speaking, a human can live without water for roughly three days. But some things, like how much water a specific body needs and how it uses water, can have an impact on this.
- Freshwater supports ecosystems and human civilizations, making it essential for life. Many areas of daily life, such as food production, electricity generation, manufacturing, and sanitation, depend on freshwater.
- Because every living thing on earth, from plants to animals to people, depends on water for survival, there would be no way for life to exist. Earth will become lifeless without water. We should only turn on the faucet when necessary to preserve water.
- Water quality is harmed by runoff from both urban and agricultural areas. Habitats are diminished when wetlands are drained for construction. The availability of groundwater is threatened by contamination and overuse. Exotic species invasion can affect local wildlife and vegetation.
- Water. The majority of chemical reactions, which make up the majority of processes that make up life on Earth, require a liquid to break down the components so that they may move around and interact freely. Because it serves as a solvent, liquid water is a necessity for life on Earth.
- Estuaries are areas where fresh and salt water mix, and they are home to a wide variety of plant and animal species. Freshwater biomes support a variety of adapted and frequently unique plants and animals. Most of the drinking water for human populations and water for agriculture are provided by freshwater biomes.

Answer:
"Human existence without access to fresh water"
Explanation:
Life on earth formed some billions of years ago when the single organism first evolved from the Cyanobacteria that generated oxygen necessary for the existence of life. Since then, life has, as we know, flourished close to the Indus Valleys, which was the source of fresh water for the humans at that time, to which they adapted.
Without dissolved oxygen in the water, life would not have been conceivable, and it is because of this that the freshness of the water is still regarded as a vital role in the continued existence of man on the face of the world.
Oceans have given man resources, and if those resources hadn't been contaminated or unfit for use by humans or other creatures, they wouldn't have been regarded as resources, and life would have undoubtedly begun in a different setting.
The glaciers and freshwater lakes left over from the ancient ice ages make up only 3% of the world's freshwater reserves. If those supplies run out, mankind will be forced to utilize desalinated water, which is produced artificially from the oceans, increasing costs and global warming.
