Earth is composed mostly of water; water surface covers more than 70% of Earth’s territory, which gives its name: The Blue Planet. It’s true that water is substantial and every living thing needs it in order to survive. Water is finite and we have to take care for it, because if we don’t use it correctly, in a near future, pure water will be impossible to find. And atthe time we make pollution we try to take care of it by cleaning it but it doesn’t depend on water plants it depends on us and how do we use it. In this project I’ll explain the uses for water, how we, humans, waste it, how to stop the pollution, and at the same time I’ll explain the types of matter of water, what is composed of, it characteristics, and essentially, why does water is so important inour daily lives.
Although water covers 70% of the Earth, only 0.007% of the fresh water in the Earth, can be directly consumed, and this means that only 0.007% of fresh water can be used for human needs for the body. Human body is mostly of water, we have almost 80% of water. So, it’s important to take care of water, because almost 4 billion of kids all around the world die annually because ofdiarrhea from drinking dirty water.
Water is an incredibly important aspect of our daily lives. Every day we brush our teethes with it, cook with water, drink water, and participate in many other activities involving water. However, even with all of the importance water holds in our lives, many of us know very little about the water, in this era of information, with so many resources immediatelyavailable, there is no reason why anyone should remain so ill informed about water.
Water is a compound chemical substance where his formula is H2O, which contains one oxygen and two hydrogen atoms which are connected by covalent bonds. At ambient conditions, water is a liquid, but it co-exists on Earth with its solid state, ice and gaseous state, water vapor, or steam. As I said inthe introduction, water covers 70.9% of Earth’s surface, and is vital for ALL known forms of life. Water is found mostly in oceans, aquifers, in the air as vapor or clouds, and precipitation. Oceans hold 97% of surface water, glaciers holds 2.4%, rivers, lakes and ponds holds 0.6% of Water. Water is constantly in a cycle of evaporation or transpiration, precipitation and runoff. Over land,evaporation contributes to the precipitation over land, which is indispensable to organisms and plants to survive. Water is a natural resource vital for the survival of humanity and all species on earth, water is destined for all human beings and their communities, people cannot do without water since it corresponds to our primary needs and constitutes a basic condition of our existence. Water is muchmore than a basic human need, is essential, an irreplaceable element to ensuring the continuance of life. All depend upon the fate of water. No water, no life. As simple as this affirmation. Because no other planets contain water, it’s impossible to find life or to live there, that’s why Earth is special, because the “Blue Planet” is the only one, as far as we know, which can hold life inside. Butaccess to safe drinking water has improved steadily and substantially over the last years in every part of the world, or almost. Observers estimate that by 2025, more than half of the population will be facing water-based vulnerability, that water demands will exceed supply by 50%! This means that in some years, water will be so necessary that harsh decisions will take over; however, we stillhave time to change the future. With small decisions in daily life, such as closing the tap while brushing your teeth in the morning can change the world. But besides our own acts, governments are making projects of purification the water in some cities, water purification is a process of removing undesirable chemicals, materials and biological contaminants from dirty water to produce water fit for...
