Communication is typically understood in terms of what is communicated. However, the importance of what is intentionally or unintentionally left out from the communication process is high in many fields, notably in communication about environmental and health risks. The question is not only about the absolute lack of information. The rapidly increasing amount and variability of available data require actors to identify, collect, and interpret relevant information and screen out irrelevant or misleading messages that may lead to unjustified scares or hopes and other unwanted consequences. The ideal of balanced, integrative, and careful risk communication can only rarely be seen in real-life risk communication, shaped by competition and interaction between actors emphasizing some risks, downplaying others, and leaving many kinds of information aside, as well as by personal factors such as emotions and values, prompting different types of responses. Consequently, risk communication is strongly influenced by the characteristics of the risks themselves, the kinds of knowledge on them and related uncertainties, and the psychological and sociocultural factors shaping the cognitive and emotive responses of those engaged in communication. The physical, economic, and cultural contexts also play a large role. The various roles and factors of absent information in integrative environmental and health risk communication are illustrated by two examples. First, health and environmental risks from chemicals represent an intensively studied and widely debated field that involves many types of absent information, ranging from purposeful nondisclosure aimed to guarantee public safety or commercial interests to genuinely unknown risks caused by long-term and cumulative effects of multiple chemicals. Second, light pollution represents an emerging environmental and health issue that has gained only limited public attention even though it is associated with a radical global environmental change that is very easy to observe. In both cases, integrative communication essentially involves a multidimensional comparison of risks, including the uncertainties and benefits associated with them, and the options available to reduce or avoid them. Public debate and reflection on the adequacy of risk information and on the needs and opportunities to gain and apply relevant information is a key issue of risk management. The notion of absent information underlines that even the most widely debated risk issues may fall into oblivion and re-emerge in an altered form or under different framings. A typology of types of absent information based on frameworks of risk communication can help one recognize its reasons, implications, and remediation.

The environment influences health and risk outcomes, and communication campaigns often strive to reduce risk and promote positive health outcomes by raising awareness, increasing knowledge, influencing attitudes, and impacting intentions and behavior. Communication campaigns should be based on good formative research and theory, and they should be implemented with fidelity and a clear evaluation plan. Communication campaigns that address environmental influences are typically focused on promoting human, animal, or environmental outcomes despite the fact that all three are interconnected and would benefit from being considered in a larger ecological framework. The One Health approach reconceptualizes environmental influences by focusing not just on the environmental but also connections with human and animal health. One Health can be applied to communication campaigns to support efforts that acknowledge and promote the complexity of these relationships. Campaigns about environmental influences on health and risk range from a longstanding campaign built on individual activities to reduce environmental and personal risk to a sun smart campaign to reduce sun exposure risk to a lead-free campaign and an asthma-control campaign concerned about air quality. Other environmental campaigns focus on tobacco prevention, obesity prevention by addressing environmental influences as part of their strategy, climate control, and ocean species preservation—and that is only a sampling of popular campaign topics. These communication campaigns face similar challenges like lack of formative research and evaluation plans as well as atheoretical approaches to influence outcomes.

Hope has been defined in primarily two ways, and both have implications for message design within health and risk communication. First, hope has been defined as a way of thinking, or disposition, that affects how people pursue goals. Dispositional hope manifests in beliefs about one’s capacity to initiate and sustain action toward goals (agency) and one’s ability to generate ways to reach those goals. Dispositional hope has been associated with positive physical and mental health outcomes. For example, high-hope women have greater intentions to engage in cancer prevention behaviors than do low-hope women. Numerous studies have associated higher hope with better pain management, and people who are higher in hope have a greater pain tolerance than people lower in hope. Hope is also related to better psychological adjustment. Much of the research on dispositional hope focuses on correlating hope with a variety of positive health and non-health outcomes; however, psychotherapeutic interventions have also been designed to increase dispositional hope. These interventions have shown improvements in health-related outcomes. Although their potential is not yet realized, interventions for developing dispositional hope could improve compliance with medical recommendations, increase adoption of health behaviors, and decrease risk behaviors. The second way that hope has been defined is as a discrete emotion. Discrete emotions are brief, intense, psychological, and evaluative reactions directed at external stimuli (e.g., people, events, or objects). In response to these external stimuli, emotions help individuals adapt to their environment by activating a unique pattern of thoughts (cognitions), physiological changes, subjective feelings, motor expressions, and action (or behavioral) tendencies. Lazarus’s cognitive-mediational theory has been one of the most influential theories of discrete emotions that includes a definition of hope. Lazarus identifies the core relational theme of hope as “fearing the worst but yearning for better.” Lazarus deems hope to be a problematic emotion because he believes hope contains both positive and negative elements. Despite uncertainty about the exact nature of hope, Lazarus believes that hope is vital to coping with stress. Hope enables people to believe in the possibility of better circumstances and therefore is critical as a coping mechanism against despair. Lazarus does not provide guidance for what a message might need to include to evoke hope. Drawing on Lazarus and appraisal theories in general, MacInnis and de Mello suggest tactics that consumer marketing advertisements could use to induce hope. Specifically, the authors focus on turning “impossibility into possibility” and enhancing “yearning.” De Mello and MacInnis also theorize that hope can lead to motivated processing of information resulting in both positive (e.g., coping, well-being, and goal achievement) and negative (e.g., risky behavior, self-deception) outcomes. Unfortunately, the theorizing of de Mello and MacInnis was never empirically tested. To further explore how feelings of hope are created, Prestin examined underdog narratives in entertainment media. Underdog narratives show characters who are attempting to meet a goal despite unfavorable circumstances and odds. These narratives evoke hope and make people more motivated to meet their own personal goals. Although their potential has not been fully explored, underdog narratives may assist individuals in overcoming challenging circumstances, such as battling addiction or developing new health habits. There are numerous mechanisms still to be examined that may explain the effects of underdog narratives beyond their ability to evoke hope. Recently, Chadwick defined hope as a future-oriented, discrete emotion that focuses on an opportunity to achieve a desired future outcome. Her definition builds on the work of Lazarus and Roseman and has implications for the design of messages that evoke hope. According to Chadwick, hope is evoked by appraisals of a future outcome as (a) consistent with goals (goal congruence), (b) possible but not certain (possibility), (c) important (importance), and (d) leading to a better future (future expectation). All four of these appraisals combine to create a perception of opportunity and the discrete emotion hope. Hope motivates behavior by focusing one’s thoughts on capitalizing on an opportunity. Chadwick states that hope also involves (a) an approach action tendency that motivates individuals to take, or continue, action to achieve the desired outcome, (b) increased heart rate and skin conductance, (c) an open facial expression, heightened focus, and alert body posture, and (d) a feeling of eager attention. Chadwick’s definition has clear implications for developing messages that evoke hope. Messages designed to create appraisals of the importance, goal congruence, positive future expectation, and possibility of a future event evoke hope and are called hope appeals. Like other theoretical explications of emotional appeals, a hope appeal has two components: (a) the inducement of hope through the presentation of an opportunity and (b) the presentation of recommended actions to achieve the desired outcome. The recommended actions component includes information designed to (a) increase the receiver’s perception of his or her ability to perform the recommended action (i.e., self-efficacy) and (b) demonstrate the ability of the recommended actions to achieve the desired outcome (i.e., response efficacy). Empirically, scholars have tested the effects of hope and messages that evoke hope. Hope appeals increase attention to messages about climate change and increase mitigation behavioral intention and mitigation behavior. In addition, feelings of hope increase interest in climate change protection and are positively correlated with pro-environmental behaviors and support for climate change policies. Feelings of hope significantly predict interest in climate protection, self-efficacy, interpersonal communication intention, information seeking intention, and behavioral intention. Hope and hopeful narratives have also been associated with greater perceived message effectiveness and more agreement with the message content. After a stressful experience that accelerates heart rate, evoking hope decelerates heart rate and decreases state anxiety. This research provides evidence that messages that evoke hope can counter the psychological and physiological effects of stressful events. In addition, researchers have examined the effects of hope on a variety of health, persuasion, political communication, and marketing outcomes. Preliminary evidence indicates that hope appeals are equally as or more effective than guilt and fear appeals at increasing interpersonal communication intention, self-efficacy, information seeking intention, and behavioral intention. In addition, hope appeals create less reactance (anger) than fear appeals. Together these results indicate that hope and hope appeals have substantial potential to influence health and risk behavior.

Central to the study of communication and cultural studies is the relationship between nature and culture, not as a rigid dichotomy, but as elements that are coconstituted by each other materially and symbolically. With the rise of ecological awareness, the past three decades has fostered an increase in scholarship addressing environmental matters explicitly, as well as professional organizations mobilizing around the ways this perspective has shaped research, teaching, and praxis. Communication scholars from a range of perspectives have contributed to ongoing conversations about “environment” as a keyword, including at least these seven general approaches: (1) environmental personal identity and interpersonal relationships; (2) environmental organizational communication studies; (3) science, technology, and health communication; (4) public participation in environmental decision-making; (5) green applied media and arts; (6) environmental mass media studies; and (7) environmental rhetoric and cultural studies. Given this rich and expanding disciplinary terrain, identifying the heart of this research is a complicated task. Environmental communication is the study and practice of pragmatic and constitutive modes of expression that define and trouble our ecological relationships within the world. It has been founded as a crisis discipline, one dedicated to addressing some of the greatest challenges of our times and to foregrounding the ethical implications of this orientation. In this article, environmental communication also is characterized fundamentally as a care discipline, one devoted to unearthing human and nonhuman interconnections, interdependence, biodiversity, and system limits. In the United States, environmental discourse has articulated dominant, residual, and emergent attitudes, values, and practices related to—though not limited to—wilderness, preservation, conservation, public health, environmental justice, sustainability, climate science, and resilience. Despite historical reluctance, future possibilities for scholarship on the environment are exigent and expanding, including communication-based research on climate justice, as well as digital environmental communication and archives.

Climate change, which includes global warming, is a serious and pervasive challenge for local and global communities. Communication theorists, researchers, and practitioners are well positioned to describe, predict, and affect how we communicate about climate change. Our theories, research methods, and practices have many potential roles in reducing climate change and its effects. Climate change communication is a growing field that examines a range of factors that affect and are affected by how we communicate about climate change. Climate change communication covers a broad range of philosophical and research traditions, including humanistic-rhetorical analyses, interpretive qualitative studies, and social-scientific quantitative surveys and experiments. Climate change communication examines a range of factors that affect and are affected by how we communicate about climate change. Much of the research in climate change communication focuses on public understanding of climate change, factors that affect public understanding, media coverage and framing, media effects, and risk perceptions. Less prevalent, growing areas of research include civic engagement and public participation, organizational communication, and persuasive strategies to affect attitudes, beliefs, and behaviors related to the climate. In all of these areas, most of the research on climate change communication has been conducted in the United States, United Kingdom, Australia, Canada, and Western European countries. There is a need to expand the climate change communication research into other regions, particularly developing countries. In addition, climate change communication has natural links to environmental and health communication; therefore, communication scholars should also examine research from these areas to develop insights into climate change communication.

When it comes to health and risk, “place” matters. People who live in lower-income neighborhoods are disproportionately affected by obesity and obesity-related diseases like heart disease, hypertension, and diabetes; asthma; cancers; mental health issues; etc., compared to those that live in higher-income communities. Contributing to these disparities are individual-level factors (e.g., education level, health literacy, healthcare access) and neighborhood-level factors such as the socioeconomic characteristics of the neighborhood; crime, violence, and social disorder; the built environment; and the presence or absence of health-enhancing and health-compromising resources. Social determinants of health—for example, social support, social networks, and social capital—may improve or further complicate health outcomes in low-income neighborhoods. Social support is a type of transaction between two or more people intended to help the recipient in some fashion. For instance, a person can help provide someone who is grieving or dealing with a newly diagnosed health issue by providing emotional support. Informational support may be provided to someone trying to diagnose, manage, and/or treat a health problem. Instrumental support may come in the help of making meals for someone who is ill, running errands for them, or taking them to a doctor’s appointment. Unfortunately, those who may have chronic diseases and require a lot of support or who otherwise do not feel able to provide support may not seek it due to the expectation of reciprocity. Neighborhood features can enable or constrain people from developing social networks that can help provide social support when needed. There are different types of social networks: some can enhance health outcomes, while others may have a more limiting or even a detrimental effect on health. Social capital results in the creation of resources that may or may not improve health outcomes. Communication infrastructure theory offers an opportunity to create theoretically grounded health interventions that consider the social and neighborhood characteristics that influence health outcomes. The theory states that every neighborhood has a communication infrastructure that consists of a neighborhood storytelling network—which includes elements similar to the social determinants of health—embedded in a communication action context that enables or constrains neighborhood storytelling. People who are more engaged in their neighborhood storytelling networks are in a better position to reduce health disparities—for example, to fight to keep clinics open or to clean up environmental waste. The communication action context features are similar to the neighborhood characteristics that influence health outcomes. Communication infrastructure theory may be useful in interventions to address neighborhood health and risk.

A study of social movements advances a people’s history of the United States, providing a window into the ways ordinary people often took extraordinary measures to make laws, workplace conditions, the educational system, the quality of home life, and public spaces more open and responsive to the needs and concerns of marginalized groups. With the rise of industrial capitalism in the early 1800s came a host of social ills that prompted individuals to form organizations that enabled them to operate as a force for social change. As the Native American Chief Sitting Bull is purported to have said, “As individual fingers we can easily be broken, but together we form a mighty fist.” The 1800s through the early 21st century provides numerous examples of people acting together as a mighty fist. As early as 1824, workers in textile mills in the Northeast United States enacted work stoppages and strikes in reaction to wage cuts and deplorable working conditions. The movement to abolish slavery in the mid-1800s provided a way for disenfranchised black men and women, such as the eloquent Frederick Douglass and Maria Stewart, as well as white women, to speak and organize publically. In the area of labor, female and black workers, excluded from the more formal organizing of trade unions through the American Federation of Labor, organized their own labor meetings (e.g., the National Labor Convention of the Colored Men of the United States), unions (e.g., the Women’s Trade Union League), and strikes (e.g., the Uprising of 20,000). By the late1800s through the 1930s, American socialism and the Communist Party, USA, influenced the philosophy and tactics employed by labor activists, many of whom were factory girls who played a formidable role in mass walk-outs in the Progressive Era. Struggles for workplace and civil rights continued throughout the 20th century to undo Jim Crow and segregation, to advocate for civil rights, to advance the rights of women in the workplace, and more recently, to fight for the rights of the lesbian/gay/bisexual/transgender communities, undocumented workers, and immigrants, and to fight against the police repression of black and brown communities and against imperialism and globalization. Activists’ tools for resistance have been as diverse as their causes and include petitioning formal legislative bodies, picketing and rallying, engaging in work stoppages, occupation of public spaces (e.g., sit-downs, walk-outs, occupying squares and parks), and most recently, using social media platforms, blogs, and other forms of Internet activism to facilitate empowerment of marginalized groups and progressive social change. The Internet has provided an important tool for facilitating international connections of solidarity in struggle. Although what follows focuses specifically on movements in the United States from roughly the 1800s to the present, efforts should continue to focus on the ways movements join forces across and around the globe.
