It already affects every continent and around 2.8 billion people around the world at least one month out of every year. More than 1.2 billion people lack access to clean drinking water.[1] Water scarcity involves water stress‚ water shortage or deficits

The importance of water: Water is the most wanted or used resource in the entire world‚ due to its demand. It is wanted and needed by everyone for various reasons‚ some of these reasons are for everyday things like drinking in order to suvive‚ cooking cleaning‚ technology and even basic things like gardning. It also helps with poverty ‚ health‚ hunger and education. Water is a blessing. If we did not have water neither of us will be here‚ so why are we thanking it by missusing or wasting it for

Water Conservation Water is essential to Earth. We need it to cook‚ bathe‚ provide power‚ control fire‚ and last but not least‚ we need it to live! Therefore‚ it is very important to human survival. When 70% of Earth is made up of water‚ you would think that we have plenty of water for our needs. But really‚ about 97% of that water is made up of ocean. We cannot use this water because it is too saline for our needs. Only 3% of Earth’s water is fresh‚ and 2% of that supply is frozen

Water is continuously being recycled in a process called the water cycle. All living things on earth need water to survive. The water cycle has no starting point and no end point. Earth’s water is always in movement and always changing forms‚ it can go from a liquid to a solid to a gas and back to a liquid. The water cycle is how we track movement of water above‚ in and on the earth. The water cycle consists of three major processes‚ condensation‚ evaporation and precipitation. Condensation is the

Access to water is an essential human need therefore; it is a basic human right. An adequate amount of safe water is necessary to prevent death from dehydration‚ and it is also used for personal hygienic requirements‚ and to simply keep sanitized. For most people across the world‚ this is very effortless and common; however for some of the unfortunates‚ access to water is a very difficult task for them. The water crisis is possibly the most severe human threat of our time‚ and the first and most

The earth has a limited amount of water.That water keeps going around and around and around in what we call the "Water cycle".It is the only way that Earth can be continually supplied with fresh water.The sun is the most important part of renewing our water supply.It can be solid (ice)‚a liquid (water)‚ or gas (water vapor). Water on earth is always changing. How do these changes happen? It is made up of a few main parts:evaporation (and transpiration)‚condensation and precipitation. Evaporation

Water scarcity and global warming Global warming is expected to account for about 20 percent of the global increase in water scarcity this century. It is predicted that global warming will alter precipitation patterns around the world‚ melt mountain glaciers‚ and worsen the extremes of droughts and floods. Global water consumption increased sixfold in the last century - more than twice the rate of population growth - and will continue growing rapidly in coming decades. Yet readily available freshwater

Water scarcity Water scarcity involves water stress‚ water shortage or deficits‚ and water crisis. The concept of water stress is relatively new. Water stress is the difficulty of obtaining sources of fresh water for use‚ because of depleting resources. A water crisis is a situation where the available potable‚ unpolluted water within a region is less than that region’s demand. Water scarcity is difficulty of obtaining water for use because of depleting resources. It occurs due to both Natural

organisms would not exist without water. Within the human body the majority of biological reactions require water to take place. Although it is possible for human survival without nutrients for up to several weeks‚ without water humans would die in a matter of days. In the human body‚ water makes up 60-70% of adult body weight. At cellular level water makes up between 70-95% of the mass of a cell. The amount of water in the human body is balanced. This balance is between water obtained from liquids consumed
