Importance Of Water In Our Life

What is water? Why is water vital to life? What makes water unique? Water is the most abundant compound on Earth and the universal solvent in which the chemistry of the life processes has developed over billions of years. Water has unique chemical and physical properties that make life on Earth possible; it plays a key role in the cycling nutrients on our planet and it is the only common substance that you can find as a solid, a liquid, and a gas. Water exists in every living being, it provides a base for vital metabolic reactions to occur in. Water is used in photosynthesis by plants, which produce oxygen – this reaction is vital for the Earth as the oxygen produced in used by living being to breathe. Water is a simple inorganic compound that accounts approximately 55-60% of the body mass of …show more content…
Chemicals can be described in term of two types of properties; physical properties and chemical properties. Water is an excellent solvent. That means that many varieties of substances can dissolve in water – forming aqueous solutions. Water is the solvent that transports many essential molecules and other particles around the body, the water on our planet also comes in contact with air. When it does, it dissolves tiny amounts of the gases in the air – some air pollutants are very soluble in water. So when it rains, the water cleans some of the pollutants out of the air including SO2 and NO2. The water crisis is the number one global risk base on impact to society (World). Water may contain toxic metals or it may be contaminated with bacteria. The world health organization and UNICEF states that more than 750 million people around the world lack access to safe water; one in nine people, 82% of those who lack access to safe water live in rural areas, while just 18% live in urban areas. More than 840,000 people die each year from a water related disease
