Yesterday I came upon a bus, idling away as it was waiting to pick up passengers at a community center suburban Chicago.
I walked past the bus, and as I did I felt its large exhaust pipe, spewing warm fumes into the air. I asked myself why the bus was left running, as nobody had gotten on board yet, or was even in sight at that moment. But the engine kept on running, and whatever the combustive process was, it kept on spitting out its results.
This week, a report was issued by the government, confirming what most of us already know: this planet is in trouble. Emissions, in the way of greenhouse gases, are threatening our long-term survival. And yet the bus keeps on idling, and we keep on doing what we’ve always done.
The bus began loading maybe four or five minutes later, and within ten minutes it was on its way. The fumes were still escaping from the bus, but it felt less wasteful because at least people were going from one place to another.
One bus won’t spell the difference between saving the planet and seeing 125 degree temperatures on a regular basis. But the symbolic meaning of an idling bus might be significant. All of us can make decisions to reduce emissions and/or waste. We can’t do anything more than that, but we can do something. And if we want to continue living here, we must.
