Ozone depleting quickly
Year Published: 1992Resource Type: Article Cx Number: CX4459 Abstract: The Earth's ozone layer is thinning about twice as rapidly as scientists previously believed, according to the U.S. Environmental Protection Agency. A study done by the EPA indicates that the layer above the United States has been depleted about four or five per cent a year since 1978, about double what had been shown for previous studies. According to EPA Administrator William Reilly, the new estimates suggest that there could be an additional 200,000 deaths from skin cancer in the U.S. over the next fifty years, which would represent a doubling of the current rate of about 5,000 skin-cancer deaths a year. |
