...Space Administration, along with scientists from several institutions, announced startling findings from atmospheric studies done by a modified spyplane and an orbiting satellite. As the two craft crossed the northern skies last month, they discovered record-high concentrations of chlorine monoxide (ClO), a chemical by-product of the chlorofluorocarbons (CFCs) known to be the chief agents of ozone destruction...
...easy to fix because CFCs are ubiquitous in almost every society. They are used in refrigeration and air conditioning, as cleaning solvents in factories and as blowing agents to create certain kinds of plastic foam. In many countries CFCs are still spewed into the air as part of aerosol sprays...
...rapid consensus that action had to be taken. In 1987 they crafted the landmark Montreal Protocol, which called for a 50% reduction in CFC production by 1999. Three years later, as signs of ozone loss mounted, international delegates met again in London and agreed to a total phaseout of CFCs by the year 2000. That much time was considered necessary to give CFC manufacturers a chance to develop substitute chemicals that do not wipe out ozone...

The most important goal is to measure how badly this fragile band, which protects the earth from the harmful ultraviolet rays in sunlight, is being depleted by the industrial chemicals known as CFCs...
