This study aims to verify the impact of environmental volunteer awareness in marine leisure, sports, or tourism on coastal ecology, economy, and youth leisure satisfaction. Firstly, questionnaires and interview tools were designed. SPSS 27.0 statistical software was used to conduct descriptive tests, t-tests, regression analysis, and Pearson correlation analysis tests on 500 valid questionnaires, and then the interview results were collected. Then, the data was sorted, classified, and compared, and finally, the discussion was conducted using multivariate test analysis. Research shows that although most teenagers agree on the necessity of volunteer literacy in marine leisure environments, there are differences in the views of teenagers of different genders. In addition, it has been confirmed that marine environment volunteer literacy has a significant positive development effect on marine ecology, rural economy, society, and environmental development (p < 0.01). Factors such as people's environmental literacy, policy cooperation, consumption convenience, risks of marine activities, professional knowledge, and technology will all have interference effects.
