7) As scientists, politicians, and concerned citizens recognize the threat of global warming to the ongoing climate change, reductions
in greenhouse gas emissions become the forefront of the discussions. To reduce the presence and persistence of greenhouse gases
in the atmosphere, their sources must be fully understood. Natural and anthropogenic sources for greenhouse gases can impact
their presence in the atmosphere. Which of the options best matches the anthropogenic sources and the greenhouse gas
accurately?
A)
Methane- rice cultivation
CFCs- livestock farming
Carbon dioxide- landfill decompogition
Eliminate
B)
Methane- corn and wheat agriculture
CFCs-fossil fuel combustion
Carbon dioxide-deforestation
Methane- fossil fuel combustion
CFCs- agricultural fertilizers
Carbon dioxide- volcanic activity
D
Methane- livestock farming and landfill decomposition
CFCs- refrigerants and propellants
Carbon dioxide- combustion of fossil fuels
