The purpose of the Montreal Protocol was to protect the ozone layer by phasing out the use and production of various ozone depleting chemicals that were causing the layer to thin and dissipate. Industry objected at first, but scientists and environmentalists prevailed.
Ozone Layer Depletion. 1  The word ozone means smelly in Greek because the gas has a strong odor. 2  CFC molecules are highly stable and can last for up to 100 years. Unfortunately, this gives them plenty of time to find their way to the ozone layer. 3  One chlorine molecule from a CFC can destroy up to 100,000 ozone molecules. Ultraviolet rays can also have bad effects on nature. They can kill plankton, which is a major source of food in the ocean's food chain.
