The Global Water Crisis
Posted November 19th,2007 by admin
Water is vital to the survival of all known life forms.Water crisis is the state of the world’s water resources in relation to human demand.Global scarcity of usable water and water pollution are the major aspects of water crisis.A lot of people around the world do not have access to clean potable water,and the numbers are growing.
Around the world,1.1 billion people are living without clean drinking water; another 2.6 billion people do not have proper sanitation,this results to death all over due to water borne diseases.
We see water all around us,yes 71% of the Earth’s surface is covered with water,but we have to understand that only a percentage of that is fit for consumption.The large water composition of our planet doesn’t mean that we have an infinite supply of useable water.By simple observation,a huge portion of the Earth’s water is salty,or locked up in ice and glaciers.
The Earth although abundant with water has a limited supply of fresh water.Oceans may be deemed as available water but the energy needed to convert salt water to fresh water is restrictive,only a fraction of fresh water can be derived from desalination,although newer technology is helping reverse the ratio.Water which is fit for consumption constitutes only a small percentage of all the water resources,and the sad thing is that it is diminishing because of contamination and pollution.
Inadequate supply of safe water and lack of sanitation accounts for the rising number of child deaths because of diarrhea.Poor supply of water for sanitation results to deaths affecting children most especially in underdeveloped countries,such deaths are considered preventable if only we can find a way how to distribute clean water properly.
Vegetation and livestock are all dependent on freshwater resources.This is our major food source and if it is threatened,it will challenge our survival as well.Overdrafting of groundwater causes decrease in agricultural yields.Low agricultural yields and deaths in livestock are direct results of water pollution.Water pollution and overuse of underground water resources truly harms biodiversity causing imbalance in nature
Armed conflicts arise over meager water resources resulting in displaced community due to this conflict.Regional conflicts arise in roughly 260 different river systems around the world.Existing international rules grants water rights among countries but still conflicts due to regional tensions on water supply are becoming a fight for survival,and warfare is inevitable.It is not just the scarcity of water that is causing death but the conflict that goes with it.
The demand for fresh,safe water increases over the course of time.Everybody must take their part in conserving water.The global water crisis will never go away if we don’t take an active part in providing our very own share.Each of us must think twice every time we turn that faucet.

global water crisis
It is generally believed that there is a good supply of fresh water. But to our disappointment, the fact is just the opposite.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. What’s more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So it’s high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.
With fresh water, the world will be prosperous
