Planning to take a road trip this summer? While it may seem kinder to the planet to roll down the windows when driving at fast speeds on the highway, it's actually a fuel-efficiency nightmare. Opening windows or the sunroof reduces the car's aerodynamic design, creating drag and lowering your average miles per gallon. Instead, stay cool by taking advantage of your car's air conditioner, which is designed to work with your car and keep you comfortable and your car as fuel-efficient as possible.

It seems any household with children has the inevitable box of worn-out, broken and unwanted crayons. Instead of throwing them out, why not put them to good use by sending them to the company Crazy Crayons? The company, which you can find at CrazyCrayons.com, employs people with developmental disabilities and gives them a job taking old crayons and making them into fun new coloring products. Over 100,000 pounds of old crayons have been made into new shapes, like stars, puzzles and more. All you have to do is box up your old crayons and send them in, and the company does the rest to turn your trash into treasure.

When kids see trash and recyclables put on the curb to be picked up, it's hard for them to understand where the stuff actually goes. The website IWantToBeRecycled.org has an educational and interactive tool to show your kids exactly where your recyclables go and what happens to them. Each recyclable tells the story of how it's collected, sorted, processed, converted and manufactured into a new product. There's even a game where your kids can become the ultimate "super sorter" and run their own interactive recycling plant.
