Commuter Bus runs on Human Waste

Read this article with Mrs. Gattermaier http://www.tweentribune.com/tween56/commuter-bus-runs-human-waste and answer the following question:

1. How would you feel riding this bus? Do you think that we will eventually have fuel made from sewage and food waste? Remember, 5 people make enough sewage and food waste each year to run a bus for about 300 km. (That is about the distance from here to Toronto and BACK!).
