Many now believe as many as 50% of cancers are attributable to environmental pollutants. The air in our own homes is tens or hundreds of times more polluted than outside air, due to the use of dangerous chemicals in cleaning products. According to the EPA, the most polluting thing most people do daily is the operation of a personal automobile. If you want to make a difference, cut back on your auto use or find transportation alternatives.
