“Governor Signs Texting Law Inspired by Teen’s Death,” the headline said. In June 2010, the governor of Georgia signed the Caleb Sorohan Act, named for an 18-year-old student who died in a car accident caused by his texting while driving. The bill made it illegal for any drivers in Georgia to text unless they were parked. After Caleb died, his family started a campaign, along with dozens of his high school classmates, to enact a texting while driving ban. They signed petitions, started a Facebook page, and used phone banks to lobby members of their state legislature. Vermont enacted a similar ban about the same time. The new laws in Georgia and Vermont increased the number of states banning texting while driving to 28. (Downey, 2010)Downey, M. (2010, June 4). Governor signs texting law inspired by teen’s death.

“Amherst Sleeps Out to Protest Climate Change,” another headline said. It was February 2010, and a student at the University of Massachusetts, Amherst, had been living in a tent for 121 days. His goal was to call attention to the importance of clean energy. The student was a member of a Massachusetts group, Students for a Just and Stable Future (SJSF), composed of college students across the state. To dramatize the problem of climate change, the group had engaged in sleep-outs in various parts of the state, including one on the Boston Common, a famed public park in that city, over a series of weekends in late 2009. About 200 students were arrested on trespassing charges for staying in the park after it was closed at 11:00 p.m. The UMass student in the tent thought he was making a difference; as he put it, “Hopefully people see me and realize that there are people out there who care about the Earth’s future and civilization’s stability enough to do something about it.” Yet he knew that improvements to the environment would take some time: “It’s not going to happen overnight.” (Vincent, 2010, p.

Societies change just as people do. The change we see in people is often very obvious, as when they have a growth spurt during adolescence, lose weight on a diet, buy new clothes, or get a new hairstyle. The change we see in society is usually more gradual. Unless it is from a natural disaster like an earthquake or from a political revolution, social change is usually noticeable only months or years after it began. This sort of social change arises from many sources, including changes in a society’s technology, as the news story on texting and driving illustrates; in the size and composition of its population, as Chapter 19 "Population and Urbanization" discussed; and in its culture. But some social change stems from the concerted efforts of people acting in social movements to alter social policy, as the news story on the student in the tent illustrates, or even the very structure of their government.
This chapter continues this book’s examination of social change that began with the discussion of population and urbanization in Chapter 19 "Population and Urbanization". The chapter begins with a conceptual look at social change and modernization before turning to sociological perspectives on social change and the sources of social change. It then presents a sociological understanding of the natural and physical environment. This focus on the environment is certainly timely in today’s world but also appropriate for a chapter beginning with social change, as environmental changes have enormous implications for changes in societies around the globe.
