This guy in Panama is building a village of houses whose walls are insulated with empty plastic beverage bottles!  Click through to watch the video.  This is a really great idea for making use of garbage, reducing construction costs, and building well-insulated homes that will require less energy to cool or heat.

BUT!  This is not a reason to drink bottled water!  Don’t think that because somebody’s found a use for the empty bottles, it’s perfectly okay to buy and discard them.  Bottled water has a huge environmental impact and on average is not as clean and safe as tap water.  Drink from the sink, refill a reusable bottle when you need to carry water, and if your local tap water is not safe, keep fighting until it is!  Bottled water should be for emergencies only, not an everyday thing.
