Water is essential for life on earth. Water is needed for growing food, keeping ourselves clean, generating power, controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it.
Water conservation: Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning, manufacturing, and agricultural irrigation.
Fresh Water Availability:
* Two thirds of the surface of the Earth covered with water, so you might be thinking why it is a problem. It is because most human uses require fresh water with about 97.5% of the water on the Earth, salt water it leaves only 2.5% to be fresh water. Furthermore, two thirds of it is made up of ice frozen in glaciers and polar ice caps. The remaining majority is groundwater with a very small fraction present above ground or in the air. * Access to safe drinking water has improved over the last decades in almost every part of the world, but approximately one billion people still lack access to safe water and over 2.5 billion lack accesses to adequate sanitation. There is a clear correlation between access to safe water and GDP per capita. * A recent report of 2009 suggests that by 2030, in some developing regions of the world, water demand will exceed supply by 50%. * Water plays an important role in the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation.
* 97 % of the Earth's water is salt water?
* The percentage of the world's total water is available to drink is less than 1 %. * Water conservation refers to reducing the usage of water and recycling of waste water for different purposes like domestic usage, industries, agriculture etc. * Over the years rising populations, growing industrialization, and expanding agriculture have pushed up the demand for water. * Efforts have been made to collect water by building dams, reservoirs and digging wells; some countries have also tried to recycle and desalinate sea water. * Water conservation has become the need of the day.
* The method of recharging ground water by harvesting rainwater is gaining importance in many cities. * Water conservation can be done through what you do, not by what you know. * In the forests, water seeps gently into the ground due to vegetation cover. This groundwater in turn feeds wells, lakes, and rivers. Protecting forests means protecting water 'catchments'. In ancient India, people worshipped Nature and one of them was Water. AT A STAKE:
The importance of protecting our water resource cannot be overstated. Regrettably, in countries like Canada that are blessed with an abundance of fresh water, there is continuous misuse and abuse of the resource: household toilets that use 20 liters per flush when 6 liters would do, and to industrial plants and municipalities that use water bodies as convenient sewers. About 70 percent of the earth’s surface is covered with water. Of that, only 0.3 percent is usable by humans. The remaining 99.7 percent is either unusable salt water or unavailable fresh water. And, most of the 0.3 percent is out of reach, locked up in icecaps and glaciers. Water is a commodity that is essential to life on this planet. Plants and animals need clean water to survive. Humans rely on finite supplies of freshwater to stay alive, without it people cannot live more than a few days. Almost everything we do uses water in some way. Unfortunately, all of earth inhabitants share 1 percent of all the water on earth. And with exploding human population growth, especially in poor countries, these finite supplies get quickly used up. The water we have now is all there will ever be. We cannot quickly produce more water. It can...
