      400M Indians Endangered By Ozone Depletion

      Scientists studying satellite data have discovered an immense
      wintertime pool of pollution over the northern Indian state of Bihar.
      The discovery was made by researchers analyzing data collected by the
      Multi-angle Imaging SpectroRadiometer aboard NASA's Terra satellite.

      Indian and U.S. scientists have reported that a dangerously declining
      ozone layer over northern India threatens the lives of 400 million people.
      A joint study by scientists of the Indian Institute of Technology at
      Kanpur and George Mason University in Virginia assessed the trend of
      ozone depletion over the Indian subcontinent using satellite and
      limited ground observations, the Press Trust of India reported Tuesday.

      The rate of ozone decline was found to be higher in recent years in
      the valley of the Ganges River than in other parts of India, said
      Ramesh Singh, one of the authors of the study.

      "This declining trend is a serious threat, especially to 400 million
      people who live in the basin," the authors reported in a paper soon to
      appear in the international Journal of Remote Sensing. Further
      investigation is needed to determine the reasons for the depletion, th
      e report states.

      Ozone is an important atmospheric trace gas that blocks harmful
      ultraviolet radiation from the sun. Manmade chemicals like chlorine
      destroy it. Decreased ozone has been linked to increases in skin
      cancer rates.

      Ground-Level Ozone Linked To Increased Mortality
      Baltimore MD (SPX) Nov 17, 2004
      Changes in ground-level ozone were significantly associated with an
      increase in deaths in many U.S. cities, according to a nationwide
      study conducted by researchers at the Johns Hopkins Bloomberg School
      of Public Health and the Yale University School of Forestry and
      Environmental Studies.
