What is one means of slowing the rate of ozone hole creation? 

A)  by increasing the production of ozone-depleting chemicals 
B)  by finding substitutes for CFCs 
C)  by not burning fossil fuels in the Antarctic 
D)  by recovering and reusing ozone-depleting chemicals

Finding substitutes for CFCs is the most effective means of slowing the rate of ozone hole creation. CFCs are one of the major contributors to the depletion of the ozone layer, and substitutes such as hydrofluorocarbons (HFCs) have been developed to reduce CFC use. Option A is incorrect because increasing the production of ozone-depleting chemicals will obviously exacerbate the problem. Option C is not practical because it is not only limited to just the Antarctic region, and it is not feasible to completely stop using fossil fuels. Option D could help reduce the depletion of the ozone layer, but it is not as effective as finding substitutes for CFCs.
