By 2025, two-thirds of the world’s population may face water shortages.

Two-thirds of the worlds population may face water shortages by 2025. Water covers 70% of our planet. However, freshwater that we use to drink in incredibly rare. We also use freshwater to bathe in and irrigate our farm fields. Only 3% of the world's water is freshwater and two-thirds of that is stuck in frozen glaciers or otherwise unavailable for our use. As a result, some 1.1 billion people worldwide lack access to water. A total of 2.7 billion find water scarce for at least one month of the year. With the existing climate change scenario, almost half the world's population will be living in areas of high water stress by 2030 including between 75 million and 250 million people in Africa. 

Sub-Saharan Africa has the latest number of water-stressed countries of any region. Inadequate sanitation is also a problem for 2.4 billion people. These are populations are exposed to diseases such as cholera and typhoid fever, and other water-borne illnesses. Two million people, mostly children die each year from diarrheal diseases alone. At the current consumption rate, this situation will only get worse. 

By 2025, two-thirds of the world's population may face water shortages. And ecosystems around the world will suffer even more. Many of the water systems have become under great pressure. These keep ecosystems thriving and feed a growing human population. Rivers, lakes and aquifers are drying up or becoming too polluted to use. More than half the world's wetlands have disappeared. Agriculture consumes more water than any other source ans water much of that through inefficiencies. Climate change is altering patterns of weather and water around the world casing shortages and droughts in some area and floods in others.
