Going to the store for every little thing is lame. I’m willing to bet you already have what you need, in your kitchen or junk drawer. And MTV SWITCH is all about repurposing.

For instance, you can…

• Stop cars from hitting your bike with a foldable ruler
• Remove hair dye with Diet Coke.
• Tone muscles by filling empty detergent bottles with water for weightlifting. Inexpensive and hardcore.

It’ll save you a trip as well as some cash.

We missed Christmas, our bad. But you probably still have plenty of birthdays coming up, and you're going to have buy something other than a card or another whoopee cushion. The Green Daily has a list of 2007's Best Green Gadgets, and many of them are a lot cooler than you may think. Solar-Powered chargers, and even a solar-powered messenger bag that charges your electronics inside. Maybe you think that's lame, but so is another year of whoopee cushions.

We're not going to tell you to stop drinking orange juice, mostly because we're not nutjobs. But it's pretty cool to look at the environmental workings of the orange juice industry, to see what separates frozen concentrated orange juice from its unfrozen ilk.

As Slate's Green Lantern points out, a little knowledge can feel as  sweet as tangy orange juice pouring down the gullet. Drink up.

Where in the world are eco-loving city dwellers? Grist, a great site for environmental news and humor, has put together a list of the world’s fifteen greenest cities and we took notice.

So visit and take a deep breath, because you can.

How cool can you look while throwing out trash? The answer is pretty cool. In fact, downright awesome. Watch this YouTube video to see some serious can-chucking skills. These guys make tossing empties a new pastime.

It’s a far cry better than littering, but I just have to ask; were all of those cans thrown in recycling bins?

As temperatures dip, it’s time to bundle up. For playing in the snow or braving the cold to get to school or work, there’s eco-friendly winter wear. Try a fleece hat created with recycled materials, nettle scarf, and eco wool gloves.

And, once at your destination, a cozy sweater can help keep you warm and the heater on low. Winter has never been so green.
