text: Although cars make everyday life easier, lessening the use of them could potentially "save the world." Polution is at an all time high and car emissions are largely to blame. In paragraph five it states that, "Passenger cars are responsible for 12 percent of greenhouse gas emissions in Euope... and up to 50 percent in some car-intensive areas in the United States." This is saying that the emissions from cars are destroying the earth. Though going to the grocery store that is two miles away may seem easier by just hoping in the car and arriving in less than five minutes, walking or biking would be better for you and the environment. Many cities are even focusing on becoming more "pedestrian friendly" to help boost the enthusiasm of cutting the use of cars. Walking is not the only option either, using hybrid cars, carpooling, or public transportation is also an option. Though still involving the use of cars, emissions would be reduced greatly. Also, emissions can cause sickness. In large cities where cars are depended on there is Smog. Smog is a thick black cloud of pollution that hangs in the air over large ciies. Smog can make you very sick if you injest it. Many people in cities that do have smog have to wear face masks when walking outside. I do not think that face masks are a new trend that everyone would like to start wearing. Lessening the use of cars around us would be a healthy step towards restoring our environment and could start a trend for others to do so aswell.
