A 2-mile-long ice core sample taken from Antarctica has shown that the levels of heat-trapping greenhouse gases are higher now than at any time in the last 420,000 years. The heat that these gases trap will cause sea levels to rise by about 3 feet, among other things. The agents responsible include coolant gases such as Freon (a trade name of the infamous CFCs, or chlorofluorocarbons), which are contained in the cooling circuits of old refrigerators, freezers, and air-conditioners. The formidable greenhouse gases are released into the atmosphere when those appliances leak or are dumped.
More than 8 million refrigerators are disposed of every year in the United States. Take your old refrigerator to a facility where it will be dealt with properly, or ask your public works department how to dispose of it correctly.
