Access to clean water is considered to be a universal human right, “a human right that is essential for the full enjoyment of the right to life” as stated by the United Nations.
However, we often take drinking water for granted. 780 million people still lack access to clean water, more than 2.5 times the population of the United States. While the demand for clean water only grows as our population increases, one of the leading international companies in global health has developed a product to provide clean water in almost any situation. The Lifestraw, created by Vestergaard.

The Lifestraw, winner of the best invention of 2005, and 2008 winner of ‘World Changing Ideas’ is a simple straw that filters water from any source. Whether it is drinking out of a puddle on the side of the road, or a parasite invested river in Africa, The Lifestraw filters water right as you drink it.
By using a microfiltration system, Lifestraw technology uses small hollow fibres with 0.2 micron pores to filter water. As you suck in water, any parasites, bacteria, and dirt get trapped inside the fibres, removing 99.99999% bacteria, and 99.9% of protozoan cysts. The Lifestraw filters 1000 liters in its lifetime, without the use of any batteries, with a filter that is five times stronger than EPA standards. Once the Lifestraw has surpassed its lifetime, water cannot filter through the straw, rendering it useless.

For the cost of only 20 dollars, Lifestraw can provide 2.7 liters of water for a year. Whether you are thirsty on a hike and need a quick source of water, or are in need of water in emergency situations, Lifestraw provides a cheap way to obtain clean drinking water.
Even if you found yourself trapped in a bathroom stall, you could drink out of the toilet like the guy in this video:
