Carbon dots (CDs) are emerging zero-dimensional fluorescent carbon nanomaterials that have attracted immense research interest due to their excellent biocompatibility, water solubility, tunable photoluminescence, low toxicity, and chemical stability. In this review, we summarize the green synthesis of carbon dots using oatmeal as a sustainable natural carbon precursor via a simple eco-friendly reflux method. Oatmeal, rich in carbohydrates, proteins, and phenolic compounds, provides an excellent renewable source for carbonization and surface functionalization. The synthesized CDs were characterized by UV-Visible spectroscopy, photoluminescence (PL), Fourier Transform Infrared Spectroscopy (FTIR), and Transmission Electron Microscopy (TEM). The CDs exhibited strong blue fluorescence, nanoscale particle size, and abundant surface functional groups such as -OH, -COOH, and -NH?. These features make them highly suitable for dermatological and cosmetic applications. Additionally, antioxidant and antimicrobial activities suggest promising applications in skincare and aesthetic formulations. This review highlights recent advancements, characterization strategies, and future prospects of biomass-derived CDs in biomedical and cosmeceutical fields. Climate change is one of the greatest challenges of the 21st century, and youth are emerging as critical agents of climate action. This review examines youth involvement in climate change mitigation and adaptation, tracing historical roles and current trends, with implications for Thane District in Maharashtra, India. Drawing on global and local assessments, the review highlights how youth participation -- through advocacy, education, community programs, and policy engagement -- has evolved. We also identify future pathways for enhancing youth contributions to climate resilience, including capacity building and institutional support. The findings underscore the urgency of empowering youth as partners in regional climate strategies.
