8. Lack of clean water is killing more people too date than war. 1 out of 6 people living doing not have a source to clean water. Almost 5,000 children die daily because they do not have clean drinking water and sanitation. This is why the search for clean water has become an epidemic throughout the world.

9. Engineers have become a top provider in ways to attain clean water; whether it be through digging wells or building dams. With the current crisis,engineers are challenged for new innovative and more sophisticated ways to reach this goal. One way bigger nations are solving this is by redirecting areas with large amount of water flow to areas where it is scarce. This is not an ideal solution for most countries and agriculture.

10. Desalination is the ability to remove the salt from salt water in order to make it drinkable. Though this is not a new idea it is hard to achieve. This idea is mainly used in the middle east. Desalination plants are expensive and require a lot of energy. Other less expensive ideas include recycling waste water, and overall trying to decrease the world's dependence on water.

5. It is a tube about 9.25 inches long and about an inch around. The outer shell of the unit is made of a durable plastic, with a string attached so someone can wear it around their necks. To use it, a person sticks the LifeStraw directly into the water source and drinks like they were using a regular straw.

6.The first prototype of LifeStraw used iodine to kill bacteria, but the 2012 version contains no chemicals. Instead, the straw uses mechanical filtration. When you suck on the LifeStraw, water is forced through hollow fibers, which have micro sized pores, which give it is nickname of micro-filtration device.. Any dirt, bacteria or parasites are trapped in the fibers, while the clean water passes through. When you finish drinking, all you do is blow air out the straw to clear the filter. This makes for quick and easy cleaning.

7. Vestergaard Frandsen says a personal LifeStraw should be able to purify about 264 gallons of water 0.7 gallons a day. This means that it will last a year before it needs to be replaced. There are no replacement parts; so a person would need a new one in roughly a year.

2. Vision is to work with the people in Haiti through communities and government. They work and maintain projects in Haiti. Projects include: water, education, and economic development.

4. 90% of the organization is dedicated to building water systems in rural communities. These water systems are used in place of river and streams for water, and they do not require electricity to use. Helps around 150,000 people.

3. Water projects include digging wells. They also try to build water systems in rural communities. Their goal is to attain clean water in the cheapest way possible.
