    Aerosol Cans, if sprayed directly into the air, will not contribute to global warming. In 1974, a chemical called chlorofluorocarbons was discovered by Nobel Prize winning scientists Dr. F. Sherwood Rowland and Dr. Mario Molina to be theoretically harmful to the Earth’s Stratospheric Zone which is a layer of the ozone that protects from ultraviolet radiation. The possible thinning of the ozone layer could potentially have increased cases of Skin Cancer and Cataracts among other environmentally noxious effects. Since chlorofluorocarbons were used in air conditioners, refrigerators, and aerosol cans, the chemical was officially banned by the US EPA (Environmental Protection Agency) in 1978; however, because the Doctors proposed the theory about it’s damaging properties, companies had already begun to discontinue use of the chemical. Since the 1980s, other countries have adopted the same bans, thus creating a safer and healthier atmosphere throughout the globe. Additionally, aerosol cans are manufactured with 25% recyclable material and can be recycled after their use.
