Only 3% of the world’s water is fresh water, and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use.As a result, 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year.Inadequate sanitation causes people to be expose to disease such as cholera and typhoid fever, and other water-borne illnesses.Rivers, lakes and aquifers are drying up or becoming too polluted to use. More than half the world’s wetlands have disappeared.By 2025, two-thirds of the world’s population may face water shortages. Ecosystems around the world will suffer even more.water pollution has cause water shortage as pesticides and fertilizers that wash away from farms, untreated human wastewater, and industrial waste flow into the rivers sea causes it to be unsuitable for drinking.Many countries that produce large amounts of food—including India, China .They need a large amount of water to produce a large amount of food to feed the large population.However ,they are close to reaching their water resource limits.The rapid population growth in the world has led to additional pressure on freshwater.
in my opinion, i think that to reduce water shortage one of the method is to create an awareness in school.To allow the students to know the consequences of water shortage and learn how to conserve the water supply by organising an activity such as a camp allowing the student to feel how is it without any water supply .If they learn now how to conserve water supply now it is more likely it will turn into a habit.Thus, their generation will conserve water supply and thus water shortage would not occur.
