Saving the planet doesn't have to be boring. It's possible to have fun and make a positive impact at the same time. Here are two examples:
A dance club in Rotterdam, Netherlands called Watt has a special dance floor requiring dancers to keep moving if they want the lights to stay on. The more people dance, the more electricity is generated which is just one of the many sustainable features of "the very first Sustainable Dance Club in the world" with a "focus on sustainability in a creative and attractive way." Of course, you'll have to know Dutch if you want to read about it on their website, but you could also read about it here. Either way, it's a dance party 1998.
An organization called PlayPumps International has been installing water pumps in Africa for villages that otherwise have little or no access to fresh, clean water. The great thing about these pumps is that they double as a playground for kids. As the kids spin around a merry-go-round, water gets pumped from deep in the ground into a storage tank. The water can then be accessed from a nearby tap. Easy access to fresh water means that less people die of horrible, water-borne diseases and the women who usually spend their time fetching water from miles away can instead spend their time in school or participating in other worthwhile activites. Also, the kids get a safe and attractive place to play, which is in itself a major benefit.
Surely there are many other ways to enact positve change and have fun while you're at it. These are just a couple examples. Let me know if you can think of others.
