Article Abstract:

National Aeronautics and Space Administration (NASA) scientists discovered that the earth's ozone layer was being depleted due to high concentrations of chlorine monoxide and bromine monoxide. These two gases are byproducts of chlorofluorocarbons and halons, chemicals commonly used in refrigerators, air conditioners, aerosol spray cans, plastic and rubber foam manufacture, and fire extinguishers. While scientists are trying to find means to stop ozone layer depletion, several countries have ratified the Montreal Protocol in 1987 to stop the use of destructive chemicals.

Article Abstract:

Some nine million Americans are unemployed due to the recession. Job losses during this recession are due to fundamental changes in the American economy and not simply a result of business cycles. Some jobs will eventually be eliminated, so laid-off workers will have to undergo training if they wish to work in occupations in expanding industries. Living standards are expected to fall as higher-paying manufacturing jobs decrease in number. A college education will prevent an erosion in living standards for most workers.

Article Abstract:

The biggest oil spill in US history was the Exxon Valdez accident in which 11 million gallons of oil were discharged into Alaska's Prince William Sound. Relative to the total volume of oil spilled in the US, it was comparatively small. However, the substantial environmental damage which was shown on TV elicited strong public reaction and spurred Congress to pass the Oil Pollution Act of 1990. Subsequent oil spills have raised questions as to the adequacy of oil-spill containment and clean-up technology.
