Final answer:
Teddy's organization aims to decrease CFCs in the atmosphere in support of the Montreal Protocol's mission to restore the ozone layer, with signs of recovery noted despite challenges.
Step-by-step explanation:
Teddy's organization is working to reduce the concentration of CFCs in the atmosphere. The initiative aligns with the goals of the Montreal Protocol, which is a global effort established in 1987 to phase out the use of CFCs that deplete the ozone layer.
Despite challenges, like the need for developing-country participation and the management of CFC "banks", there have been indicators of success such as observable signs of ozone recovery. Replacements for CFCs include hydrofluorcarbons (HFCs) and hydrochlorofluorocarbons (HCFCs), which are more benign to the ozone layer.
