Sustain without invention!

I recently have noticed a poster for a unique movement in Winnipeg. It especially stood out to me since I am a person living on my own, without a vehicle. On top of that, since signing my life over to the Faculty of Architecture, affording a vehicle is not possible. The poster was advertising a car sharing community, so to speak. It's catch heading is "Need a car? But only sometimes?". This is exactly how I feel... I think I might have actually said "yes" out loud. I think that this type of initiative is exactly the type of thinking that must accompany new design, new product, and new invention. It is true that there are thousands of brilliant solutions out there to help people lessen their impact on the earth. From low-flush toilets and low-flow shower heads to electric cars, our everyday habits are leaving a much shallower footprint on the environment. However, truly the best solution is to CHANGE the way that we do things. If we all still own a vehicle, electric or not, they must still be produced, they must still take up space, and eventually they will need to be disposed of somewhere. By sharing a car, we will take public transit more, save money, and lighten the landfill load by lowering the quantity of vehicles being produced, and thus disposed of. Just as we do not have to flush every time, and I'm very sure we all could take shorter showers, sharing a car is a step into a greener evolutionary society, without any technology at all!
