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 o grupo consume y las emisiones de gases de efecto invernadero que generan. Al usar menos automóviles privados y más transporte público, bicicletas y caminar, la familia consume menos energía fósil y reduce sus emisiones de gases de efecto invernadero. Esto lleva a una disminución de su huella ecológica.

Answer:

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