Question

clarice and her family change their use of transportation. they use their private automobile less often, and instead rely more on public transportation, bicycles, and walking. how does their change in behavior affect their ecological footprint?
a the footprint decreases, because the family uses fewer energy resources and reduces their emissions of greenhouse gasses.
b the footprint decreases, because the family travels across a smaller area of land.
c the footprint increases, because vehicles such as buses and subways use more energy than a private automobile.
d the footprint is not affected, because the familys use of resources is approximately the same as before.

Explanation:

El huella ecológica se refiere a la cantidad de recursos naturales que una persona, grupo o actividad consume y las emisiones de gases de efecto invernadero que produce. El uso de transporte público, bicicletas y caminar en lugar de un automóvil privado reduce el consumo de combustible fósil y las emisiones de dióxido de carbono y otros gases de efecto invernadero. Además, el transporte público es más eficiente en términos de energía al transportar a múltiples personas a la vez.

Answer:

A. The footprint decreases, because the family uses fewer energy resources and reduces their emissions of greenhouse gases.
