Two Seattle tour companies have launched Travelers Against Plastic to motivate travelers and tour operators to say "no" to disposable plastic water bottles and choose other methods of ensuring their water is safe to drink.
Crooked Trails and Wildland Adventures launched the website, which allows travelers to make a no-plastic-bottle pledge, on March 22. By last week, 136 people and 10 tour operators had signed the pledge.
Eight of 10 single-serving plastic water bottles wind up in landfills, according to the Recycling Institute. About 34.6 billion bottles are emptied annually in the U.S.
Chris Mackay, co-founder of TAP and executive director of Crooked Trails, says her guests are told to be prepared to clean their own water on their travels. In 2008, a guide to Machu Picchu in Peru watched in disbelief, Mackay says, as her group filled their water bottles from a waterfall, then cleaned the water.
