It can be hard to remember in a country where fresh, safe tap water flows in everyone's home, but clean water is very precious almost everywhere else on this planet.
More than 663 million people around the world don't have access to clean water, and every day over 800 children die from drinking contaminated water.
To remind people how lucky they are, and to raise money for clean water in developing countries, water bottle company One Water will be selling a limited number of bottles with special sleeves that make the water look "dirty."
The bottles, which were unveiled on World Water Day, will be on sale soon.
Duncan Goose, the company's founder, realizes that customers may not want to buy "dirty" water, but he says it's important to raise awareness.
"I wanted to turn this into a force for good," he said in a statement, "a source of funds that benefits the billions of people worldwide who don't have a reliable clean source of water."
To make sure everyone has access to clean water like their customers, One Water uses their profits to fund charities in the developing world, including their own One Foundation.
Grossing people out with dirty water may not solve the world's problems, but it's definitely creative.
Last year, Americans drank 12.8 billion gallons of bottled water, which works out to 30.8 gallons per person. If everyone thought about that water differently, it could make a huge difference in the world.
What do you think of these gross bottles? Are they a good idea?
