Water is found in an abundant amount, everywhere on earth, from polar ice caps to geysers. Two-thirds of the earth’s surface are covered by water and the human body is made up of 75% water. On average, an adult body contains 42 liters of water and only 2.7 percent of water loss can result in dehydration, fatigue, nervousness and irritability. Wherever there is water on earth, there is life. Whether it be frozen or in a liquid form, whether it be deep sea hydrothermal vents or in deserts, you can be sure to find life there, like microbes or other organisms.
This is evident enough that water is the most important substances found on the earth. All living things need water in order to survive. If there was no water, then there would be no life on earth. Without water, there would be no plants or vegetables or foods, no oxygen for humans and animals to breathe and the planet would look completely different than it is today. Besides drinking water to quench our thirst, water also has a bunch of other several uses. Water is important for bodily functions like transporting foods and nutrients, replenish nutrient, carry waste materials, lubricate our joints etc.
4 Major Importance, Benefits, Advantages of Water
1 Oxygen production
Plants produce oxygen or breathable air for humans and animals. Plants have the ability to convert two water molecules into oxygen through a series of biochemical reactions. On land, this process is prevented by a process called decomposition in which the microorganisms in the soil consume oxygen from dead animals or organisms and produce organic matter called carbon dioxide. This process also occurs in water, like oceans or rivers by algae. But when they die and they sink to the ocean floor, their biomass are not decomposed through a man oxygen-consuming process. This process is believed to have led to being the original cause for oxygenation of the earth’s atmosphere.
2 Existence of life
Life cannot exist without water. Water, like oxygen, is a primary necessity to sustain life on earth. One theory called ‘Panspermia’ states that life on earth was created when icy comets crashed into the earth and formed the precursors of life. The tiny organic molecules or precursors would not have survived if there was any water. The solidified water on the comets protected the molecules from harsh radiation. “One possibility is that because the building blocks are frozen within the water, it has this protective mantle around it that could be delivered,” says Ralf Kaiser, a physical experimental chemist at the University of Hawaii at Manoa.
