Water is important because it is one of the best solvents in nature. Living systems require solvents in order to mix various chemicals with one another, and water is the best substance for the job. According to Public Broadcasting Systems, living organisms need water because the biochemical processes of life must take place in a fluid.Know More
Water is a good solvent in part because it is a polar molecule. According to WorldofMolecules.com, this means that polar and ionic substances, such as salt, readily dissolve in water. Water's properties as a solvent allow it to promote life because rather than having to transport solid materials, organisms can dissolve metabolites and nutrients in water, allowing them to move more easily through the body. Many organisms use water to flush toxins and poisonous by-products from their bodies as well. Water also facilitates the bending of enzymes, allowing them to produce necessary chemical reactions within the body quickly.
Water is also an important component of temperature control for animals and it is useful for transporting dissolved substances, according to HowStuffWorks.com. Moreover, water is necessary to sustain life on a larger scale as well. It allows humans to grow crops, raise livestock, travel and power factories. Because it exists in solid and gaseous forms as well as liquid, the environment is able to store water as ice and water vapor, making it readily available.Learn more in Bodies of Water
Rivers are important because they transport water, provide habitat, support economic activities and enable transportation. Rivers provide life-sustaining supplies of water and important nutrients for living organisms around the world, including humans, plants and fish. Large rivers provide power for hydroelectricity and facilitate the movement of people and goods within nations and across borders.Full Answer >
The Amazon River and its tributaries are important for local agriculture, for transportation and as a source of hydroelectric power. Unfortunately, the Amazon's economic value is also a leading cause of environmental degradation in the area.Full Answer >
The Great Lakes are important because they contain 20 percent of the world's fresh water and exhibit tremendous biodiversity. They are also a vital water source and play an important role in transportation and the U.S. and Canadian economies.Full Answer >
The Nile River is important because it provides Egypt with irrigation, hydroelectric power, a steady water supply and rich soil. It was the lifeblood of ancient Egyptian transport, commerce and agriculture, and remains crucial for sustaining life in the barren deserts of Egypt today. At over 4,000 miles long, it is the longest river in the world.Full Answer >
