Reduce pollution by bringing the outdoors into the home
把戶外帶進家裡來降低污染
Almost everyone agrees that outdoor air pollution is a substantial problem. But few know that indoor air pollution can also be unhealthy. The EPA claims that indoor air can be more seriously polluted than the outdoor air of even the largest cities. Most people spend over 90 percent of their time indoors where glues, paints, cleaners and other chemicals surround them. So, people are turning to nature’s air pollution solution: plants.
Besides producing valuable oxygen, there are some indications that houseplants can improve air quality by removing nasty chemicals from the air. NASA partnered with another organization to test how well 15 kinds of houseplants absorbed three specific chemicals found in homes and offices. In the test, large numbers of certain kinds of plants removed as much as 87 percent of the polluting chemicals in a 24-hour period. Results like these make it easy to see how having more houseplants equals cleaner air. But what about life in cities where space is scarce? What about people who just don’t have room for many plants?
