As projections of climate change effects in the media persist, current research suggests that threatening climate change content circulating social media and knowledge of threats to the Earth system and human health may lead to the development of eco-anxiety. If social media exposure to climate change content influences eco-anxiety, there is a need for psychological interventions to help manage climate change-related negative affect. A systematic review was conducted 1) to investigate the relationship between the use of social media and eco-anxiety in young adults and 2) to explore methodological factors involved in eco-anxiety research, including measurements and potential moderating factors. The review included seventeen articles that studied the measurements of eco-anxiety, the relationship between social media and eco-anxiety, or negative affect related to climate change and potentially moderating risk factors. A thematic analysis of the included articles yielded four central themes: (1) The Operationalization of Eco-anxiety, (2) Climate Change Perceptions and their Effects on Impairments, (3) The Relationship between Social Media Usage and Eco-anxiety, and (4) Potential Factors Influencing Climate Change Perceptions. The results suggest that eco-anxiety is real and common, especially amongst young people, and that it may be reliably measured using the Climate Change Anxiety Scale. Due to the limited and heterogeneous literature on the problem, no definitive conclusions can be drawn about how potential factors influence eco-anxiety. Future research should further explore the relationship between social media and eco-anxiety. In addition, the problem of eco-anxiety should be studied in underrepresented, vulnerable populations at higher risk for weather-related events.

While people are scrolling through their various social media apps, they encounter messaging that does not necessarily promote good mental health. Rather, images, posts, and videos often make a mockery of those with mental health problems, leaving the viewers to believe that mental health problems often lead to dangerousness, criminality, and unpredictability. It then is essential that social media messaging about mental health, and its stigmas are analyzed and solutions to promote better mental health messages on these platforms are implemented because they affect everyone. Anti-stigma campaigns may be useful in bringing awareness to mental health and its stigmas, so two anti-stigma campaigns, Stamp Out Stigma and StigmaFree, were analyzed in this study. To understand the types of messages people are receiving about mental health and its stigmas from anti-stigma organizations on social media platforms, three research questions were developed. A thematic analysis was conducted that included 205 posts from 2021 that came from the campaigns' Facebook and Twitter accounts. Several themes emerged for each research question as well as multiple limitations for this study. Ultimately, social media messaging about mental health and its stigmas must continue to be researched.

COVID-19 has shocked the bedrock of society, impacting both human life and the economy. Accompanying this shock has been the psychological distress inflicted onto the general population as a result of the emotion strain stemming from isolation/quarantine policies, being sick with COVID-19, dealing with COVID-19 losses, and post-COVID syndrome and its effect on quality of life. The psychological distress has been experienced by the general population, but compared to middle age (30-50) and older adults (>50 years of age), it has been young adults (18-30 years old) who have been more psychologically affected (Glowacz & Schmits, 2020). Psychological distress, specifically anxiety and depression, has been exacerbated by feelings of uncertainty, fear of illness, losing loved ones, and fear of post-COVID syndrome. Post-COVID syndrome, as with other post-viral syndromes such as post viral SARS involve lingering symptoms such as myalgic encephalomyelitis or Chronic Fatigue Syndrome (CFS), and loss of motivation (Underhill, 2015). In addition to these symptoms, patients suffering from post-COVID syndrome have also presented brain inflammation and damaged brain blood vessels (Meinhardt et al., 2021), Endotheliitis (Varga et al., 2020), CV abnormalities and changes in glucose metabolism (Williams et al., 2020). CV abnormalities and changes in glucose metabolism are connected to chronic illnesses like diabetes and heart disease respectively. These chronic illnesses are then associated with higher risk for depression as a result of the stress induced by the symptoms and their impact on quality of life (NIMH, 2021). Further monitoring, and research will be important to gauge ultimate physiological and psychological impact of COVID-19.

Collective human attitudes influenced by macro-forces that impact environmental issues are partially correlated to our behaviors for the good and the harm of the planet. In this thesis, I will explore how collective human attitudes contribute to pro-environmental behaviors, common and pre-existing frames of mind on major conservation dilemmas, and finally suggest future directions on how humans could be inclined to take on more environmental responsibility through an increase in human-environmental connectivity. It is found that humans are largely driven by institution structures, education, and social influence. In conclusion, more efforts should be placed to further analyze these structural incentives for pro-environmental behaviors and use them to make environmental stewardship more accessible for all people and diverse circumstances. This can be done by evaluating the human dimensions of what influences human attitudes and behaviors, how to use these forces to systematically influence pro-environmental choices, applying these structural forces to main conservation issues, and further incorporating moral discourse into the environmental research in order to appeal correctly to all aspects and perspectives. Only when human connectivity is understood in relation to the natural sciences will we be able to make positive change in the direction of a healthier Earth.
