Cars are used by almost everyone in cities across the US; most families own more than one car. Due to this a lot of our greenhouse gasses are going up in our atmosphere. There are simple solutions, such as carpooling, driving fuel-efficient cars, or using public transport. Recently, many places locally in the bay area have been setting up bike-sharing stations all around their cities. Companies basically purchase bikes and make them available to individuals anywhere in the city. All people have to do is pay a small fee to rent the bike to get from point A to point B. In urban areas like the bay area, this is great for people to get around the city and create fewer greenhouse gasses in our atmosphere.
