We depend on water for survival.More than 40% of the worlds population is deprived of household safe piped water. Thanks to population growth, global warming and pollution clean water is becoming less and less. The demand for water is doubling every 20 years and before 2030 this demand will exceed the world’s supply by over 50 percent. All this is where lifestraw comes in.
What is lifestraw? In simple words its a straw which literally purifies water killing 99.99% of waterborne bacteria and 99.9% of parasites. What makes this product unique is the way and time span it purifies it in. You literally put one end of the straw in the water and drink from the other, just like you would with a normal straw. Its that simple. Its available for around $20 from eartheasy.com which is a bargin considering it filters up to a 1000 liters. You can get more information about lifestraw from Vestergaard
