text: My grandfather who live in Cali, Colombia for example, dislikes relying on his car so much to travel places. Many times, he walks to certin locations beacuse he explained to people who lives on his street the damage car oil and gas can effect the communtiy harmfully. To many people, driving cars is the normal way to get to places, but to others, walking is their best option.    In the passage "Unmasking the Face on Mars" the Face was not created by aliens, it is just a natural landform. For one, the Face resembles land forms on Earth. Two, NASA is a professional agency, why would they not tell the truth. Three, the images themself prove that the Face is just a natural landform.
