Water Conservation
WATER Conservation
INTRODUCTION: 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.
THE CRISIS: * 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,
