select the correct answer.
how does conservation help to reduce air pollution?
a. saving water means that less runoff water will carry pesticides into waterways and into the air through evaporation.
b. using fewer fossil fuels, such as gasoline for a car, reduces the emission of burned pollutants into the air.
c. reusing, reducing, and recycling reduces the number of landfills needed.

Explanation:

To determine how conservation reduces air pollution, analyze each option:

• Option A: Saving water relates to water pollution (runoff carrying pesticides to waterways/air via evaporation), not directly air pollution reduction.
• Option B: Using fewer fossil fuels (e.g., gasoline) means less combustion, which reduces emissions of pollutants (like CO, NOₓ, particulate matter) into the air. This directly addresses air pollution from fossil fuel use.
• Option C: Reusing/reducing/recycling reduces landfills, which impacts land pollution (and maybe air pollution from landfills, but less directly than fossil fuel use reduction for air pollution).

So Option B is correct as it directly links conservation (fewer fossil fuels) to reduced air pollutant emissions.

Answer:

B. Using fewer fossil fuels, such as gasoline for a car, reduces the emission of burned pollutants into the air.
