Read the passage:

Beep! Beep! Have you ever looked outside your car window and noticed the amount of traffic on the road? There are many reasons that people jump in their cars and drive. They could be going to work, school, the library, the coffee shop, the grocery store, sporting events, or even just out for a drive. The reasons are endless. However, driving a car is a major source of air pollution that is contributing to our changing climate. One way that you can reduce air pollution is by riding a bike. Every time someone chooses his or her bicycle over a vehicle, it cuts down the pollution in your community and the environment. The main reason is that bikes don't use any fuel, which means they don't emit toxins into the air. Also, it takes less energy to assemble a bike than a car. To assemble a car, it needs to be completed in a large factory. These factories emit harmful toxins into the air. For example, did you know painting cars adds about 40 million pounds of pollutants into the air? Pollution not only impacts the environment but also our bodies when we breathe it in. Ultimately, you have a choice. Next time you need to get somewhere close to home, choose a bike instead of a car. Although a vehicle is convenient to get to places that are farther away, you can still make a difference. Choose the well-being of yourself and your environment!
