In this lesson, we will discover the reality and limitations of privacy and surveillance. We will learn the laws that protect us directly, and others that enable the security services to protect us from harm. We will then think about the tension that exists between these two sets of laws. In addition, we will consider the different technology that we encounter in our daily lives and the privacy implications of these. Finally, we will learn about how intrusive social media is in its harvesting of data, and become more informed about the data that they are making available through our engagement with technology, as well as the, environmental impacts of social media.
