Chemistry, Technology, Society, and the Environment
Today we benefit in many ways from chemical understanding and technologies. Each benefit, however, has risks associated with it. The risks and benefits of chemical processes and technologies affect us either directly or indirectly. Many people either on their own, in groups, or through their elected government officials assess these risks and benefits. They ask questions such as the following:
• Is it dangerous to use natural gas to heat my home?
• Why is the cost of gasoline so high?
• Is my water really clean enough to drink and use safely?
• How does rust degrade machinery over time?
During your chemistry course this year, you will study the interactions among science, technology, society, and the environment. These interactions are abbreviated as STSE. Throughout the textbook in examples, practice problems, activities, investigations, and features STSE interactions are discussed. The issues that appear at the end of some units are especially rich sources for considering STSE interactions. In these simulations, you are encouraged to assess and make decisions about important issues that affect society and the environment.
