CFCs were banned because they were causing ozone depletion,allowing hazardous UV rays to penetrate earth's atmosphere.
Examples of chlorofluorocarbons (CFCs) include CFC-11 (trichlorofluoromethane), CFC-12 (dichlorodifluoromethane), and CFC-113 (trichlorotrifluoroethane). These chemicals were commonly used as refrigerants, propellants in aerosol sprays, and solvents, but their production has been phased out due to their harmful effects on the ozone layer.
CFC Freon.
ChloroFluoroCarbon is the full form of CFC.
The chemical formula for chlorofluorocarbons (CFCs) typically follow the pattern CClxFyHz, where x, y, and z can vary depending on the specific CFC compound. For example, one common CFC is CCl2F2, known as dichlorodifluoromethane.
Yes! Once cfc's are released into the atmosphere the travel into the statosphere where they linger for hundreds of years & under the influance of sun light a chlorine atom is released from the cfc molecule.

the years of 1975 and 1987
They happened because of ozone depleting substances. CFC's are one of them.
The ozone hole happened when CFC's introduced. It caused due to depleting property of CFC's.
Nothing really!
Earlier CFC emissions were less because they were mostly released through industrial processes like refrigeration and aerosol production before regulations limited their use. As awareness of their harmful effects on the ozone layer grew, international agreements such as the Montreal Protocol were put in place to phase out CFC production and use. This has significantly reduced CFC emissions over time.
The international agreement to limit CFC production is the Montreal Protocol. This treaty was designed to phase out the production and consumption of ozone-depleting substances, including CFCs, in order to protect the Earth's ozone layer. The Montreal Protocol has been successful in reducing CFC levels in the atmosphere and has been hailed as an example of effective global cooperation.
CFC-11 and CFC-12 are chlorofluorocarbons, which are synthetic compounds that were once commonly used as refrigerants and propellants. These chemicals are now known to significantly deplete the ozone layer in the Earth's stratosphere, leading to the development of the Montreal Protocol to phase out their production and use.
It is mainly due to the impact of westerlies. Westerly winds carry the CFC's to the poles where they cause depletion.
Ozone layer is getting depleted. It is due to CFC's used.

The Production Budget for What Just Happened was $27,000,000.
