Who pays?
Article Abstract:
The Montreal Protocol on Substances that Deplete the Ozone Layer was signed mainly by industrial countries. Most Third World countries did not sign because they could not finance the technological changes required to stop the production and use of chlorofluorocarbons (CFCs). Moreover, in their attempt to keep pace with industrial countries, developing nations are producing and using more CFC-using technology such as air conditioners and refrigerators. Industrial nations responded in Jul 1990 by setting up a $240 million fund for Third World technology that does not use CFCs and other ozone-depleting chemicals. United Nations agencies have also set up similar funds.

Has the National Aeronautics and Space Administration (NASA) exaggerated the threat of ozone layer depletion?
Article Abstract:
It is believed that there is not enough evidence regarding chlorine monoxide and its destruction of the ozone layer. The National Aeronautics and Space Administration (NASA) has also been accused of sensationalism in releasing news about how fast the ozone layer is being depleted. However, the head scientist for NASA's second Airborne Arctic Stratosphere Expedition (AASE II) points out that evidence has been collected and studied over a six-year period. Moreover, while 0.5 parts of chlorine monoxide are found per billion by volume in the stratosphere, this translates to an alarming 20% depletion of the ozone layer in less than one year.

Ozone hole discovered
Article Abstract:
British scientists discovered a hole in the ozone layer over Antarctica in 1985. Because the theory of ozone depletion was generally unaccepted, the team was funded by the US Chemical Manufacturers Assn, which wanted to solve the problem of chlorofluorocarbons (CFCs) in the atmosphere, rather than the British government. It was discovered that CFCs were drawn to the South Pole by the polar vortex and broke down into chlorine monoxide which depleted the ozone layer with sunlight as a catalyst. Since then, the US and other nations have taken steps to stop the production of CFCs and other chemicals harmful to the atmosphere.
