Without clean water, many people (especially the young) had suffered from diarrhoeal diseases (especially in developing countries); contributing to approximately 1.5 million deaths every year, or 4000-6000 deaths per day due to dehydration. In addition, the contaminated water resulted in health defects such as reduced personal productive time, nausea, stomach pains and more. To make it worse, many developing countries have little health care to aid these people.
The Lifestraw is a straw that’s capable of filtering dirty water to be drank immediately through a straw. INGENIOUS! Put into numbers: The Lifestraw is capable of filtering a maximum of 1000 litres of water, whilst removing 99.99% of bacteria, parasites, viruses and other things harmful. Lifestraw Family (a similar product) can filter out 18000 litres of water. With the use of the Lifestraw, people around the world can have access to clean drinking water; therefore causing fewer sicknesses and diminishing the deaths associated with diarrhoeal diseases.
Although the target market of the Lifestraw was to be people in developing countries, the cost of manufacturing the Lifestraw is expensive (to buy it in Canada is about $5.50. I’m unsure of how much it takes to manufacture it though). The Lifestraw is a tube of about 10 inches made from a durable plastic with a string around it for people to wear. Within the life straw contains a mesh that would filter out larger impurities, and then a polyester filter to filter out bacteria. Afterwards, the water goes though iodine-coated resin beads which kill bacteria, parasites and viruses. A carbon filter removes any taste from the iodine and absorbs the impurities of the water to be drank (refer to http://science.howstuffworks.com/environmental/green-tech/remediation/lifestraw.htm for more information on how it works).
In the end, I would say that the Lifestraw is possibly one of the greatest inventions ever made, as it helps people in need in developing countries while also temporarily helping in the issue of the Earth’s diminishing clean water supply. I only hope in the future that the Lifestraw can be manufactured more cheaply to be distributed all across countries with little amounts of clean water.
