As a Seattle resident, I am a full supporter of our already amazing bus system. We have readily available, cheap, reliable and safe busses that run off of electronic systems and hybrid fuel technology. here's more: Walking & Biking When you travel on your own two feet, or by riding a bicycle, you reduce global warming pollution to zero. Nada. Nothing. Simple as that. But when you drive, you release 20 lbs. of carbon dioxide pollution per gallon of gas. Let’s put that into perspective. Let’s say twice a week, you rent a DVD from a store a mile from your home, and you always drive there in a car that gets about 21 miles per gallon, the Illinois average. In one year, this trivial amount of driving releases almost 400 lbs of global warming pollution. And that’s what you’ll save by walking or biking. Plus 60 bucks worth of gas, too. Carpooling Almost as simple as walking and biking. One car carrying four people to and from work every day releases just 25% of the carbon dioxide pollution that four separate cars would. Plus, if you rotate drivers every week, three of you can work or nap! Using Mass Transit The key to mass transit is the word "mass". The more of us who use it, the more global warming pollution it saves. That's because a bus or train releases more CO2 into the air than a car, but a bus or train holds many, many more people and thus keeps all those cars off the road. A bus with just 7 passengers is more fuel efficient than the average car. A full bus? Six times more efficient. And a full train? A whopping 15 times more efficient. But just how much carbon dioxide pollution does riding the bus save? Well, imagine that you and 49 of your neighbors all drive your own cars 20 miles round-trip every day between home and work. Together, you’re releasing 118 tons of CO2 into the atmosphere every year. If all of you took the bus? 92 tons. If all of you took the train? 61 tons.
