Three years ago, I published Save The Environment for Free, a post detailing some of the novel ways that you can help save our environment without having to spend a dime. Today, I’d like to talk about water.

Many of us are used to simply going to the kitchen for a cool and refreshing drink of fresh clean water, but over 800 million people worldwide lack access to clean water, and over 3 million people die from water-related disease each year.

Various charities are collecting donations to provide wells and water filtration to communities in need, but Children’s Safe Drinking Water is taking a new approach by providing two ways for you to provide clean water for free.

If you’re on Facebook, visit PUR’s Daily Drop to donate 10 liters of clean water for the cost of nothing more than a few clicks. If you aren’t already on Facebook, this may be the perfect reason to join.

If you have an iPhone or Android-powered phone, get the CauseWorld app. You’ll gain an average 5 karmas for every store you log visiting. Once you’ve gained 100 karmas, you can cash them in to provide 50 days worth of clean water for a child. 50 days worth of clean water for every 20 stores that you visit is not a bad deal at all, and you aren’t obligated to spend anything more than the effort (and perhaps gas) that it takes to visit the stores.

Want to provide more than just a few liters of clean water per day? Please consider making donations to Children’s Safe Drinking Water, Water.org, and Charity: Water.
