Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized. These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage. We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.” 64．What is the main idea of the first paragraph?
