Pick Safe Paints
According to the Environmental Protection Agency, architectural coatings such as paints and varnishes are the second-largest source of fumes from volatile organic compounds, substances that evaporate at room temperature and react in sunlight to form photochemical smog. Look for cans with "No VOC." We'll all breathe easier. (If you don't use the whole can, you can find out how to recycle the rest.)
