Two-thirds of our earth’s surface covered with water. It plays a vital role in cooling the land and sustaining life. It provides habitat for multiple ecosystems as well as allows people to grow food, carry waste, generate power, as well as many other functions of daily living.
The world’s total water supply is enormous, only a tiny fraction of it is available and usable by the human population. Scientists believe that water consumption over the next 25 years will be six times what it is today.
Around the world, roughly 1.2 billion people lack even marginally adequate access to drinking water.
Nearly 80 percent of all diseases in developing nations are associated with water shortages. Every year, poor sanitary conditions cost the lives of twelve million people.
The lack of water causes severe food shortages.
The United Nations estimates that this number could increase six-fold by the year 2025.
Because water is an indispensable basic human requirement, shortages of this resource affect all areas of development work.
Without adequate access to water, farmers in many regions cannot harvest a sufficient amount of food.
Yet, people waste water in their homes without even realizing it.
We have become so accustomed to have a 24-hour supply of water to meet all of our needs from cooking, to cleaning, to drinking, that we sometimes forget that we do not have an infinite supply of water.
Demands are increasing every year for water while resources are becoming more and more limited.
In the next two decades a 40% increase expected in water demand.
This increase in water demand trigger by various factors including growing population, increased agricultural needs, industrial use of water and water needed for electricity production.
One of the factors for the depleting water resources is water pollution.
Water pollution affects us directly through the contaminants that may enter our drinking water.
Contaminated groundwater may carry bacteria and other metals that can cause health problems.
It also affects us indirectly through the contaminated ecosystems that then become contaminated food sources for us.
We can prevent further water pollution by conserve water by turning off the tap when running water is not necessary. This helps prevent water shortages and reduces the amount of contaminated water that needs treatment.
We must be careful about what we throw down our sink or toilet. Avoid throw paints, oils or other forms of litter down the drain.
It is advisable to use environmentally household products, such as washing powder, household cleaning agents and toiletries.
Be very careful and try not to overuse pesticides and fertilisers. This will prevent runoffs of the material into nearby water sources.
Plant more plants in our garden because this can help preventing fertiliser, pesticides and contaminated water from running off into nearby water sources.
In addition, one of the most import thing that all of us must do is do not throw litter into our rivers, lakes or oceans.
Take initiative by clean up any litter that we see on beaches or in rivers and lakes.
Do our part effectively and help our planet for a better life.
