Which human action would help reduce global warming
Reducing carbon emissions by using public transportation, carpooling, biking, or walking instead of driving alone.
A. Ride a bicycle rather than walk to school
B. Eat less red meat so fewer cattle need to be raised.
C. Clear more forests to produce more farmland
D. Use more fertilizers to increase crop production
B. Eat less red meat so fewer cattle need to be raised.
This action would help reduce global warming as the livestock industry is a significant contributor to greenhouse gas emissions, particularly methane. Eating less red meat would decrease the demand for cattle and reduce the production of methane, ultimately helping to combat global warming.
Which compares the effectiveness of methane and nitrous oxide as a greenhouse gas with that of carbon dioxide
Methane and nitrous oxide are both more potent greenhouse gases than carbon dioxide. Methane is around 25 times more effective at trapping heat in the atmosphere than carbon dioxide over a 100-year period, while nitrous oxide is around 298 times more effective than carbon dioxide. This means that even though carbon dioxide is the most abundant greenhouse gas, methane and nitrous oxide have a greater warming potential on a per-molecule basis.
A. Only methane is a more effective greenhouse gas than carbon dioxide
B. Only nitrous oxide is a more effective greenhouse gas than carbon dioxide
C. Both methane and nitrous oxide are more effective greenhouse gases than carbon dioxide.
D. Neither methane nor oxide is a more effective greenhouse gas than carbon dioxide
C. Both methane and nitrous oxide are more effective greenhouse gases than carbon dioxide.
This means that both methane and nitrous oxide have a higher warming potential than carbon dioxide on a per-molecule basis.
Which human agricltural practice leads to the breaking down of chemicals and nitrous oxide production
A. The use of synthetic ferilizers
B. cutting down trees to plant crops
C. the use of community landfills
D. raising cattle on natural grasslands
A. The use of synthetic fertilizers
The use of synthetic fertilizers in agriculture can lead to the breakdown of chemicals in the soil, resulting in nitrous oxide production. Nitrous oxide is a potent greenhouse gas that contributes to global warming.
