Access to Clean Water
Water is an necessity to all life. Without water, people and animals would die within days and plants would not be able to survive.
Some people in the world, around 780 Million, still lack access to clean water. This means that either their water supply is contaminated or that they do not have a source of water at all.
Two types of water borne illnesses include cholera and typhoid fever.
Water borne illnesses can be in the water and can negatively affect the human body. Drinking contaminated water can lead to things such as being sick to death. Pollution comes from industrial waste and also fecal matter. Some symptoms of people carrying these types of illnesses includes excessive diarrhea and vomiting.
There are certain ways to prevent these illnesses and purify the water. Few are effective and both cost friendly, and that is the main issue with fixing this grand challenge. One way that people can clean water is through a water treatment plant, however which is very expensive and hard to find people willing to donate for in third world countries. Basic ways of purifying water include boiling water and using purification tablets, both of which either take some time or require resources. Salt water can also be transformed into fresh water, which can be used when people are in natural disasters and such.
