One of my favorite tops is this
blue t-shirt that I picked up this past spring. It's quite amazing and frightening if you think about it: "All the water that ever has been or ever will be is here..."
Most of the water on this planet is salt water, in the form of oceans, seas, etc. A good portion of the world's rivers, lakes, and springs aren't safe to drink without cleaning, filtering, processing, and even boiling. People in developed nations use a ton more fresh, potable water than those in developing or "third world" nations. Wars have been fought and are still being fought over water rights and access to clean water.
Now, all I'm asking you to do is think about it. And, if you can, look at your own water consumption. How long is your shower each day? Do you turn the water off when you brush your teeth or wash your hands? How often do you water your lawn? Do you buy bottled water, when you could be filling your Nalgene or Camelbak with the same stuff from your tap?
Until next time, ride long and keep the rubber-side down.
