Which of the following is an approach to minimizing global warming? 

A)  reduce the phosphorous and nitrogen in soaps 
B)  stopping the production of CFCs 
C)  dispersing methane from landfills to prevent explosions 
D)  taxing gasoline and carbon dioxide emissions

Taxing gasoline and carbon dioxide emissions is a widely accepted approach to minimizing global warming as it incentivizes individuals and corporations to reduce their use of fossil fuels which emit large amounts of carbon dioxide, a major contributor to global warming. The revenue generated from these taxes can also be used towards funding renewable energy research and infrastructure. Options A and C are specific solutions to other environmental problems but not effective in minimizing global warming. Option B refers to a past problem (depletion of the ozone layer) that has largely been addressed through the Montreal Protocol, but is not as pertinent to global warming as the continued use of fossil fuels.
