Letter to Editor by Louise Shawkat, Medford Mail Tribune, November 24, 2017; also in Ashland Daily Tidings, November 27, 2017
Recent Mail Tribune articles have addressed health issues and climate change. Despite the effect of transportation exhaust on human health, we still give vehicles a pass. Petroleum hogs-like motorbikes, cars, trucks, buses, and trains spew fine particulates that reach tiny hidden spaces in our lungs, nesting and causing heart and lung problems. Adding further complication, toxic ground level ozone forms when sunlight hits air containing nitrogen oxides and volatile organic compounds in automobile exhaust.
