People have changed. The world has changed. If we got to a point where we need to drink water in plastic bottles, we surely have changed! Humans have now reached an increasing volume of 7.3 billion people on the planet. If each one of us drink only one bottle a day, we are looking at 2.6 trillion bottles a year. Where are they? Where do they go? We can reuse plastic bottles in many other applications such as: Home insulation, temporary shelters after disasters, Agriculture land drainage.
