Background: Climate change, a pressing global health issue, impacts ecosystems, environments, and human health, leading to disrupted food systems, reduced crop nutritional value, and increased hunger. Objective: This review covers the food insecurity and mental health challenges that are among the complex impacts of climate change. Method: In this review, we bring together the data from existing research from various reliable databases, such as PubMed, Web of Science, and Google Scholar. Our intent is to unravel the complex links between climate change-induced food insecurity and mental health challenges. Results: The review discussed the direct and indirect influence of climate change on mental health, such as the causes of increased stress, anxiety, and depression arising from climate-induced disasters and their socioeconomic effects. The study drives home the crucial requirement for mitigation and adaptation strategies, including going green and transitioning to renewable energy, enhancing agricultural resilience, and providing mental health support to those affected. Thus, this review highlights effective interventions for tackling these interrelated problems. Conclusion: The future vividly demonstrates the necessity of interdisciplinary cooperation, policy alignment, and universal partnership to create a sturdier and environmentally friendly future. Taken together, this review suggests that a strong effort is necessary to address the multifaceted crisis of climate change and food insecurity, including mental health-related issues. Fostering resilience and adaptability will build healthier and more secure communities, mitigating the worst consequences of global warming.
