which action would help reduce global warming?
a. Use more plastic products.
b. Use more electricity.
c. Use more fuel-efficient cars.
d. Use more paper products.
c. Use more fuel-efficient cars.
The action that would help reduce global warming is c. Use more fuel-efficient cars.
Using more fuel-efficient cars can significantly reduce greenhouse gas emissions and decrease the amount of carbon dioxide released into the atmosphere. Fuel-efficient cars consume less fuel or use alternative energy sources such as electric or hybrid engines, which results in lower carbon emissions and less contribution to global warming.
The action that would help reduce global warming is option c: Use more fuel-efficient cars.
To understand why this option is the correct choice, let's analyze the other options:
Option a: Using more plastic products is not a suitable action for reducing global warming. The production and disposal of plastic products contribute to the emission of greenhouse gases, exacerbating global warming.
Option b: Using more electricity alone cannot reduce global warming. The generation of electricity from fossil fuels, such as coal and natural gas, releases greenhouse gases. However, if the electricity comes from renewable energy sources like solar, wind, or hydroelectric power, it can contribute to reducing global warming.
Option d: Using more paper products is not an effective action for reducing global warming. The production of paper requires cutting down trees, which act as carbon sinks, absorbing carbon dioxide, a greenhouse gas. Additionally, the manufacturing process of paper emits greenhouse gases and contributes to deforestation.
Now, let's look at why option c is the correct choice:
Option c: Using more fuel-efficient cars helps reduce global warming. Fuel-efficient cars consume less fossil fuels, resulting in lower greenhouse gas emissions. These vehicles are designed to achieve higher gas mileage by incorporating technologies like hybrid engines, electric motors, and lightweight materials. By reducing the amount of greenhouse gas emissions from transportation, fuel-efficient cars play a vital role in combating global warming by minimizing the carbon footprint associated with transportation.
Therefore, option c, using more fuel-efficient cars, is the action that would help reduce global warming.
